Linear maps as sufficient criteria for entanglement depth and compatibility in many-body systems
Maciej Lewenstein, Guillem Müller-Rigat, Jordi Tura +1
Physical transformations are described by linear maps that are completely positive and trace preserving (CPTP). However, maps that are positive (P) but not completely positive (CP)…
Entanglement and non-classical states of light in a strong-laser driven solid-state system
Javier Rivera-Dean, Philipp Stammer, Andrew S. Maxwell +6
The development of sources delivering non-classical states of light is one of the main needs for applications of optical quantum information science. Here, we demonstrate the gener…
Qubit-environment entanglement outside of pure decoherence: hyperfine interaction
Tymoteusz Salamon, Marcin Płodzień, Maciej Lewenstein +1
In spin-based architectures of quantum devices, the hyperfine interaction between the electron spin qubit and the nuclear spin environment remains one of the main sources of decohe…
Attosecond Physics and Quantum Information Science
M. Lewenstein, N. Baldelli, U. Bhattacharya +14
In this article, we will discuss a possibility of a symbiosis for attophysics (AP) and quantum information (QI) and quantum technologies (QT). We will argue that within few years A…
One-axis twisting as a method of generating many-body Bell correlations
Marcin Płodzień, Maciej Lewenstein, Emilia Witkowska +1
We demonstrate that the one-axis twisting (OAT), a versatile method of creating non-classical states of bosonic qubits, is a powerful source of many-body Bell correlations. We deve…
Quantum Random Number Generators : Benchmarking and Challenges
David Cirauqui, Miguel Ángel García-March, Guillem Guigó Corominas +5
We discuss the current state of the art of Quantum Random Number Generators (QRNG) and their possible applications in the search for quantum advantages. To this aim, we first discu…
Quantum electrodynamics of intense laser-matter interactions: A tool for quantum state engineering
Philipp Stammer, Javier Rivera-Dean, Andrew Maxwell +5
Intense laser-matter interactions are at the center of interest in research and technology since the development of high power lasers. They have been widely used for fundamental st…
The Coming Decades of Quantum Simulation
Joana Fraxanet, Tymoteusz Salamon, Maciej Lewenstein
Contemporary quantum technologies face major difficulties in fault tolerant quantum computing with error correction, and focus instead on various shades of quantum simulation (Nois…
Boundary-induced singularity in strongly-correlated quantum systems at finite temperature
Ding-Zu Wang, Guo-Feng Zhang, Maciej Lewenstein +1
Exploring the bulk-boundary correspondences and the boundary-induced phenomena in the strongly-correlated quantum systems belongs to the most fundamental topics of condensed matter…
Modern applications of machine learning in quantum sciences
Anna Dawid, Julian Arnold, Borja Requena +26
In this book, we provide a comprehensive introduction to the most recent advances in the application of machine learning methods in quantum sciences. We cover the use of deep learn…
Quantum approximate optimization algorithm for qudit systems
Yannick Deller, Sebastian Schmitt, Maciej Lewenstein +5
A frequent starting point of quantum computation platforms are two-state quantum systems, i.e., qubits. However, in the context of integer optimization problems, relevant to schedu…
Efficient Simulation of Quantum Many-body Thermodynamics by Tailoring Zero-temperature Tensor Network
Ding-Zu Wang, Guo-Feng Zhang, Maciej Lewenstein +1
Numerical annealing and renormalization group have conceived various successful approaches to study the thermodynamics of strongly-correlated systems where perturbation or expansio…
Scar States in Deconfined Lattice Gauge Theories
Adith Sai Aramthottil, Utso Bhattacharya, Daniel González-Cuadra +3
The weak ergodicity breaking induced by quantum many-body scars (QMBS) represents an intriguing concept that has received great attention in recent years due to its relation to unu…
Unsupervised detection of decoupled subspaces: many-body scars and beyond
Tomasz Szołdra, Piotr Sierant, Maciej Lewenstein +1
Highly excited eigenstates of quantum many-body systems are typically featureless thermal states. Some systems, however, possess a small number of special, low-entanglement eigenst…
