Irreversible quantum evolution with quadratic generator

AE Teretenkov - … Analysis, Quantum Probability and Related Topics, 2019 - World Scientific
We review results on GKSL-type equations with multi-modal generators which are quadratic
in bosonic or fermionic creation and annihilation operators. General forms of such equations …

Classical simulation of non-Gaussian fermionic circuits

B Dias, R Koenig - Quantum, 2024 - quantum-journal.org
We propose efficient algorithms for classically simulating fermionic linear optics operations
applied to non-Gaussian initial states. By gadget constructions, this provides algorithms for …

Concept of orbital entanglement and correlation in quantum chemistry

L Ding, S Mardazad, S Das, S Szalay… - Journal of Chemical …, 2020 - ACS Publications
A recent development in quantum chemistry has established the quantum mutual
information between orbitals as a major descriptor of electronic structure. This has already …

Correlation paradox of the dissociation limit: A quantum information perspective

L Ding, C Schilling - Journal of Chemical Theory and Computation, 2020 - ACS Publications
The interplay between electron interaction and geometry in a molecular system can lead to
rather paradoxical situations. The prime example is the dissociation limit of the hydrogen …

Mode entanglement in fermionic and bosonic Harmonium

JO Ernst, F Tennie - New Journal of Physics, 2024 - iopscience.iop.org
Mode entanglement in many-body quantum systems is an active area of research. It
provides crucial insight into the suitability of many-body systems for quantum information …

Quantum correlations in molecules: from quantum resourcing to chemical bonding

The second quantum revolution is all about exploiting the quantum nature of atoms and
molecules to execute quantum information processing tasks. To boost this growing …

Single-electron entanglement and nonlocality

D Dasenbrook, J Bowles, JB Brask… - New Journal of …, 2016 - iopscience.iop.org
Motivated by recent progress in electron quantum optics, we revisit the question of single-
electron entanglement, specifically whether the state of a single electron in a superposition …

Non-markovian quantum mpemba effect

DJ Strachan, A Purkayastha, SR Clark - arXiv preprint arXiv:2402.05756, 2024 - arxiv.org
Since it's rediscovery in the twentieth century, the Mpemba effect, where a far-from-
equilibrium state may relax faster than a state closer to equilibrium, has been extensively …

Fermionic systems for quantum information people

S Szalay, Z Zimborás, M Máté, G Barcza… - Journal of Physics A …, 2021 - iopscience.iop.org
The operator algebra of fermionic modes is isomorphic to that of qubits, the difference
between them is twofold: the embedding of subalgebras corresponding to mode subsets …

Entanglement and correlation in two-nucleon systems

AT Kruppa, J Kovács, P Salamon… - Journal of Physics G …, 2021 - iopscience.iop.org
We examine mode entanglement and correlation of two fermionic particles analytically and
numerically. We study the one-and two-mode entropies and a global characteristic, the one …
