754. WE-Heraeus-Seminar 26 Sep - 29 Sep 2021 Where: Physikzentrum Bad Honnef Scientific organizers: Dr. Sven Ramelow, HU Berlin - PD Dr. Frank K hnemann, Fraunhofer IPM, Freiburg In the last two decades, the ability to prepare and manipulate quantum states at the individual level has led to a wide range of scientific activities. It is expected that the laws of quantum mechanics with phenomena such as quantum entanglement and quantum superposition will revolutionize a wide range of fields, now frequently coined the so-called 'second generation' quantum technologies. The area of quantum sensing is considered to be one which most likely is going to deliver real-world applications and products soon. Sensing with light in the form of imaging, microscopy, spectroscopy or other interferometric methods has always played an enormous role. As an example, quantum imaging aims at utilizing the properties of quantum optical states to overcome the limits of classical imaging. This seminar will cover theoretical and experimental aspects of sensing with quantum light. Topics will include modalities like sensing with undetected photons via nonlinear interferometers, sensing with squeezed light, induced, spectroscopy with entangled light, the generation of highly non-degenerate photon, high-dimensionally entangled light and their application potential for sensing tasks. By bringing together established scientists from leading research groups in the field, junior scientists and graduate students, participants from fundamental and applied physics and industry the seminar aims at providing a vibrant forum for the exchange of ideas and discussion. The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.

Title: Optimization of Reversible Circuits Using Toffoli Decompositions with Negative Controls Abstract: ? The synthesis and optimization of quantum circuits are essential for the construction of quantum computers. This paper proposes two methods to reduce the quantum cost of 3-bit reversible circuits. The first method utilizes basic building blocks of gate pairs using different Toffoli decompositions. These gate pairs are used to reconstruct the quantum circuits where further optimization rules will be applied to synthesize the optimized circuit. The second method suggests using a new universal library, which provides better quantum cost when compared with previous work in both cost015 and cost115 metrics; this proposed new universal library 'Negative NCT' uses gates that operate on the target qubit only when the control qubit's state is zero. A combination of the proposed basic building blocks of pairs of gates and the proposed Negative NCT library is used in this work for synthesis and optimization, where the Negative NCT library showed better quantum cost after optimization compared with the NCT library despite having the same circuit size. The reversible circuits over three bits form a permutation group of size 40,320 (23!), which is a subset of the symmetric group, where the NCT library is considered as the generators of the permutation group.

Dr. Naomi Nickerson from PsiQuantum will present at 6pm on October 4, 2021. NOTE : This talk will be both in-person and virtual. The virtual link will be posted in an update. Abstract Fusion based quantum computing with silicon photonics A linear optical approach to quantum computing offers highly coherent qubits, high fidelity single qubit gates, and probabilistic entangling operations that can be implemented using well-known quantum optical methods. The key advantage of photonic quantum computing is the fact that the required photonic chips can be produced in conventional fabrication facilities used for commercial silicon photonics, allowing scaling to achieve large-scale error correction. In this talk I will introduce fusion-based quantum computing (FBQC) - a model of universal quantum computation which is ideally suited to a linear optical quantum computing platform. FBQC offers performance improvements compared to previous schemes, and significant architectural simplifications, enabling hardware made up of many identical modules, requiring an extremely low depth of operations on each physical qubit and reducing classical processing requirements. Bio: Dr. Naomi Nickerson leads the quantum architecture team at PsiQuantum, a Palo Alto-based startup building a fault-tolerant, silicon-photonic quantum computer. After earning her PhD in the theory of quantum error correction between Imperial College London and Oxford University, she worked as a software engineer in San Francisco before joining PsiQuantum to design quantum error correction for photonic quantum computing.

We will explore U(1) lattice gauge theories with topological terms in D=1,2 and 3 spatial dimensions. For D=1, we scrutinize mass perturbation theory at small positive and negative fermion masses, with the latter case being inaccessible for MCMC. In D=2 we provide a resource efficient formulation of the Hamiltonian which can be used for both, tensor networks and quantum computations, and which works for all values of the coupling. In addition, it can be generalized to non-abelian groups and higher dimensions in a straightforward fashion. In our practical example in D=2 we use this formulation to simulate negative fermions masses and find an indication of a phase transition. In D=3 we provide a Hamiltonian formulation of the topological term, including non-abelian theories and explore the phase diagram of the model. Our results suggest a second order topological phase transition at strong coupling.

Topic title: Quantum interference of light Abstract: Quantum physics has risen from an approach to understand the fundamentals of nature to a property to be harnessed by numerous technological applications that extend to our daily life. The discrete spectra of atoms and molecules is perhaps the most visible aspect of quantum physics, yet there are other aspects that are so subtle that have yet to be fully harnessed. Among them is quantum superposition, or the ability of a system to potentially adopt distinct properties simultaneously. Beyond its philosophical implications, such as negating realism, that any object should have well-defined intrinsic properties, superposition is rising to be at the core of the emerging technology of quantum information, which could potentially overcome us in the future with a new form of computing and other technologies. Superposition manifests most visibly via interference, and photons, quantized packets of light, can be used to show it vividly through interference. From photons interfering with themselves, to biphotons, or twin photons entangled in peculiar ways, experiments at the single-photon level help us understand the subtle aspects of superposition. They constitute a convenient platform for learning about superposition and for teaching it to a future workforce.

734. WE-Heraeus-Seminar 24 Oct - 28 Oct 2021 Where: Physikzentrum Bad Honnef Scientific organizers: Prof. Dr. Stefan Tautz, FZ J lich - Prof. Dr. Peter Puschnig, U Graz, Austria - Prof. Dr. Mathias Richter, PTB Berlin This seminar has been postponed from December 2020 to October 2021 due to the corona pandemic. Angle-resolved ultraviolet photoemission spectroscopy is arguably the most direct method of addressing the (filled) electronic structure critical for the electronic and optical properties of matter. The photoemission tomography technique, a combined experimental/theoretical approach based on interpretation of the photoelectron angular distribution in terms of a one-electron initial state, has been very useful in the characterizations of electronic properties of molecular films from sub-monolayers to multilayers. This includes the unambiguous assignment of emissions to particular molecular orbitals, their reconstruction to real space orbitals, the deconvolution of spectra into individual orbital contributions beyond the limits of energy resolution, the extraction of detailed geometric information, and the precise description of the charge balance and transfer at the interfaces. Despite these successes, the theoretical description of the angular distribution of photoelectrons remains challenging and is - at the current level of theory - presently crude. Moreover, there has been significant progress in momentum space imaging photoemission spectrometers with extensions to the spin- and time-resolved domains, which make present models inadequate. The seminar will bring together experts and young researchers interested in the application and the future developments of momentum space imaging of matter. The major aim of the seminar is to set photoemission tomography on firm grounds and to identify the directions for future theoretical and experimental investigations. The scope of the seminar includes but is not limited to Photoemission tomography and photoelectron diffraction Limitations of the plane wave final state approximation Real space orbital reconstruction and phase retrieval Theoretical advances: Time dependent DFT, multiple scattering theory Experimental advances: Imaging spin-and time-resolved detectors, high harmonics generation etc. Valence band electronic structure of organic molecular films and 2D materials The conference language will be English.

Particle physicists have developed numerous classical algorithms to process data from high-energy particle collisions. Computational efficiency is an important criteria for selecting collider data analysis strategies, which is often weighed more heavily than physics performance. Could quantum algorithms change the kinds of analysis tools we use for collider physics? Could quantum principles like superposition and unitary inspire new kinds of classical algorithms? Drawing on examples from the study of jets from quantum chromodynamics, I explain some of the conceptual challenges for developing quantum algorithms for collider physics and some of the quantum-inspired advances that have already found applications.

The talk will encompass applications across risk management, portfolio optimization and machine learning. Algorithms will be discussed at a high level of technical detailand there will be time for question and answers. The algorithms covered will include quantum amplitude estimation for risk analysis, quantum optimization and quantum kernel estimation methods for machine learning.

Game Changing science and technologies that will transform business and everyday lives In the UK, through strong collaboration between academia and industry, we are accelerating the development, industrialisation and adoption of quantum science and technologies in application areas such as sensing and metrology, computing and simulation, communication and imaging. There are some huge breakthroughs across automotive, healthcare, infrastructure, telecommunications, cybersecurity and defence. The UK alone counts for around half of the quantum businesses in Europe. Real-life projects are evolving such as miniature satellites being developed to provide ultra-secure communications using quantum technology, development of quantum-enabled gas sensors that detect industrial leaks and the creation of advanced receivers flagging to companies if the data they are transmitting has been accessed by others. More recently the newly launched National Quantum Computing Centre funded through UKRI has been established to work with business, government and the research community to accelerate the development of quantum computing by addressing the challenges of scalability.

Title: Quantum material characterization for streamlined qubit development Qubits are the main building blocks of quantum devices: improving their performance at every stage of development is thus crucial. A qubit's properties such as its coherence time are directly affected by their architecture and design as well as by the materials chosen. Building a qubit to test each possible variable adds an unnecessary overhead to the characterization effort: this is why it is desirable to develop fast and efficient benchmarks at earlier stages in the process. In this webinar, application scientists Ed, Clemens, Jim and Jelena will demonstrate how lock-in amplifiers operating at frequencies well below the qubits themselves offer a prime way to probe and understand material properties relevant for qubit coherence while keeping measurement times and complexity to a minimum. In this webinar you will learn: - What the basic working principles of semi- and superconducting qubits are, including hybrid approaches; - How material properties can influence a qubit's coherence; - How to characterize materials for qubits quickly and efficiently with a lock-in amplifier; and - How to characterize frequency and loss fluctuations in readout resonators.

28 Nov - 01 Dec 2021 Where: Physikzentrum Bad Honnef Scientific organizers: Prof. Marzena Szymanska, U College London, UK - Prof. Jacqueline Bloch, CNRS, France - Dr. Paulo Santos, PDI Berlin This seminar has been postponed from June 2020 to November 2021 due to the corona pandemic. Quantum simulation, the use of a controllable quantum system to mimic the operation of other, more complex quantum systems, provides a pathway for solving quantum problems with a complexity level not accessible by classical computers. This quantum technology is presently classified as a leading approach to solve complex many-body problems with potential applications in the design of new materials and drugs. The WE-Heraeus Seminar aims at bringing together experts in this emerging field to train students (at the MSc and PhD Levels) and young researchers interested in the area and discuss recent developments in a stimulating and informal atmosphere. The three-day seminar will consist of 17 tutorial-like lectures (50 min long) as well as 8 specialized talks (approx. 25 min long) covering topics such as (i) theoretical basis for quantum simulation, (ii) state-of-the-art of different platforms for quantum simulation (e.g., optical lattices of cold atoms, superconducting qubits, photonic simulators); (iii) novel concepts for scalable quantum processing and simulation exploring strongly coupled light-matter states, (iv) theoretical models for strongly correlated and dissipative systems, and (v) application of topological protection for robust quantum simulation. The scientific program will be complemented by poster sessions where the participants can present their results and discuss them with experts in the field. The exchange and cross-fertilization of ideas enabled by the seminar is expected to strengthen existing collaborations and foster new ones as well as enhance the visibility of the field. The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.

Theoretical predictions of the properties and dynamics of quantum many-body systems of importance to nuclear physics research, from field theories to dense and/or non-equlibrium matter to systems of neutrinos, require, in many instances, beyond classical computational resources. As highlighted by Feynman and others, such systems may be amenable to quantum simulations in the future. The very first steps are now being taken towards this objective. I will discuss the potential and status of this newly emerging area of quantum simulations for nuclear physics.
