Is Lindblad for me?
Martino Stefanini, Aleksandra A. Ziolkowska, Dmitry Budker +6
The Lindblad master equation is a foundational tool for modeling the dynamics of open quantum systems. As its use has extended far beyond its original domain, the boundaries of its…
Statistics of the Random Matrix Spectral Form Factor
Alex Altland, Francisco Divi, Tobias Micklitz +2
The spectral form factor of random matrix theory plays a key role in the description of disordered and chaotic quantum systems. While its moments are known to be approximately Gaus…
Oscillators with imaginary coupling: spectral functions in quantum mechanics and quantum field theory
Bruno W. Mintz, Itai Y. Pinheiro, Rui Aquino
The axioms of Quantum Mechanics require that the hamiltonian of any closed system is self-adjoint, so that energy levels are real and time evolution preserves probability. On the o…
Quantum-walk search in motion
Himanshu Sahu, Kallol Sen
In quantum computing, the quantum walk search algorithm is designed for locating fixed marked nodes within a graph. However, when multiple marked nodes exist, the conventional sear…
A simple coin for a entangled walk
Ahmadullah Zahed, Kallol Sen
We analyze the effect of a simple coin operator, built out of Bell pairs, in a Discrete Quantum Random Walk (DQRW) problem. The specific form of the coin enables us to find an…
Emergent Gauge Symmetries and Quantum Operations
A. P. Balachandran, I. M. Burbano, A. F. Reyes-Lega +1
The algebraic approach to quantum physics emphasizes the role played by the structure of the algebra of observables and its relation to the space of states. An important feature of…
Distributed sampling, quantum communication witnesses, and measurement incompatibility
Leonardo Guerini, Marco Túlio Quintino, Leandro Aolita
We study prepare-and-measure experiments where the sender (Alice) receives trusted quantum inputs but has an untrusted state-preparation device and the receiver (Bob) has a fully-u…
Reconstructing quantum states with generative models
Juan Carrasquilla, Giacomo Torlai, Roger G. Melko +1
A major bottleneck in the quest for scalable many-body quantum technologies is the difficulty in benchmarking their preparations, which suffer from an exponential `curse of dimensi…
Joint measurability meets Birkhoff-von Neumann's theorem
Leonardo Guerini, Alexandre Baraviera
Quantum measurements can be interpreted as a generalisation of probability vectors, in which non-negative real numbers are replaced by positive semi-definite operators. We extrapol…
Client-friendly continuous-variable blind and verifiable quantum computing
Nana Liu, Tommaso F. Demarie, Si-Hui Tan +2
We present a verifiable and blind protocol for assisted universal quantum computing on continuous-variable (CV) platforms. This protocol is highly experimentally-friendly to the cl…
Quantum steering beyond instrumental causal networks
R. V. Nery, M. M. Taddei, R. Chaves +1
We theoretically predict, and experimentally verify with entangled photons, that outcome communication is not enough for hidden-state models to reproduce quantum steering. Hidden-s…
A formalism for steering with local quantum measurements
A. B. Sainz, L. Aolita, M. Piani +2
We develop a unified approach to classical, quantum and post-quantum steering. The framework is based on uncharacterised (black-box) parties performing quantum measurements on thei…
Continuous-variable supraquantum nonlocality
Andreas Ketterer, Adrien Laversanne-Finot, Leandro Aolita
Supraquantum nonlocality refers to correlations that are more nonlocal than allowed by quantum theory but still physically conceivable in post-quantum theories, in the sense of res…
Noncontextual wirings
Barbara Amaral, Adán Cabello, Marcelo Terra Cunha +1
Contextuality is a fundamental feature of quantum theory and is necessary for quantum computation and communication. Serious steps have therefore been taken towards a formal framew…
Fidelity witnesses for fermionic quantum simulations
M. Gluza, M. Kliesch, J. Eisert +1
The experimental interest and developments in quantum spin-1/2-chains has increased uninterruptedly over the last decade. In many instances, the target quantum simulation belongs t…
