An operational definition of quantum information scrambling
Gabriele Lo Monaco, Luca Innocenti, Dario Cilluffo +3
Quantum information scrambling (QIS) is a characteristic feature of several quantum systems, ranging from black holes to quantum communication networks. While accurately quantifyin…
Dimensional Reduction in Quantum Optics
Jannik Ströhle, Richard Lopp
One-dimensional quantum optical models usually rest on the intuition of large scale separation or frozen dynamics associated with the different spatial dimensions, for example when…
Multicritical dissipative phase transitions in the anisotropic open quantum Rabi model
Guitao Lyu, Korbinian Kottmann, Martin B. Plenio +1
We investigate the nonequilibrium steady state of the anisotropic open quantum Rabi model, which exhibits first-order and second-order dissipative phase transitions upon varying th…
On the origin of force sensitivity in tests of quantum gravity with delocalised mechanical systems
Julen S. Pedernales, Martin B. Plenio
The detection of the quantum nature of gravity in the low-energy limit hinges on achieving an unprecedented degree of force sensitivity with mechanical systems. Against this backgr…
Simulating 2D lattice gauge theories on a qudit quantum computer
Michael Meth, Jan F. Haase, Jinglei Zhang +11
Particle physics underpins our understanding of the world at a fundamental level by describing the interplay of matter and forces through gauge theories. Yet, despite their unmatch…
Finite Pulse-Time Effects in Long-Baseline Quantum Clock Interferometry
Gregor Janson, Alexander Friedrich, Richard Lopp
Quantum-clock interferometry has been suggested as a quantum probe to test the universality of free fall (UFF) and the universality of gravitational redshift (UGR). In typical expe…
Optimal baseline exploitation in vertical dark-matter detectors based on atom interferometry
Fabio Di Pumpo, Alexander Friedrich, Enno Giese
Several terrestrial detectors for gravitational waves and dark matter based on long-baseline atom interferometry are currently in the final planning stages or already under constru…
Atomic diffraction from single-photon transitions in gravity and Standard-Model extensions
Alexander Bott, Fabio Di Pumpo, Enno Giese
Single-photon transitions are one of the key technologies for designing and operating very-long-baseline atom interferometers tailored for terrestrial gravitational-wave and dark-m…
Two-photon-transition superadiabatic passage in an nitrogen-vacancy center in diamond
Musang Gong, Min Yu, Yaoming Chu +6
Reaching a given target quantum state with high fidelity and fast operation speed close to the quantum limit represents an important goal in quantum information science. Here, we e…
Quantum field theory for multipolar composite bosons with mass defect and relativistic corrections
Tobias Asano, Enno Giese, Fabio Di Pumpo
Atomic high-precision measurements have become a competitive and essential technique for tests of fundamental physics, the Standard Model, and our theory of gravity. It is therefor…
Thermal cycle and polaron formation in structured bosonic environments
A. Riva, D. Tamascelli, A. J. Dunnett +1
Chain-mapping techniques combined with the time-dependent density matrix renormalization group are powerful tools for simulating the dynamics of open quantum systems interacting wi…
Quantum scrambling via accessible tripartite information
Gabriele Lo Monaco, Luca Innocenti, Dario Cilluffo +3
Quantum information scrambling (QIS), from the perspective of quantum information theory, is generally understood as local non-retrievability of information evolved through some dy…
Petz recovery maps for qudit quantum channels
Lea Lautenbacher, Vinayak Jagadish, Francesco Petruccione +1
This study delves into the efficacy of the Petz recovery map within the context of two paradigmatic quantum channels: dephasing and amplitude-damping. While prior investigations ha…
Time dependent Markovian master equation beyond the adiabatic limit
Giovanni Di Meglio, Martin B. Plenio, Susana F. Huelga
We derive a Markovian master equation that models the evolution of systems subject to driving and control fields. Our approach combines time rescaling and weak-coupling limits for…
