Quantum speed limits—primer, perspectives, and potential future directions

MR Frey - Quantum Information Processing, 2016 - Springer
Fundamental physical limits on the speed of state evolution in quantum systems exist in the
form of the Mandelstam–Tamm and the Margolus–Levitin inequalities. We give an …

Quantum speed limit for physical processes

MM Taddei, BM Escher, L Davidovich… - Physical review …, 2013 - APS
The evaluation of the minimal evolution time between two distinguishable states of a system

Quantum speed limits for information and coherence

B Mohan, S Das, AK Pati - New Journal of Physics, 2022 - iopscience.iop.org
The quantum speed limit indicates the maximal evolution speed of the quantum system. In
this work, we determine speed limits on the informational measures, namely the von …

[HTML][HTML] Quantum coherence sets the quantum speed limit for mixed states

D Mondal, C Datta, S Sazim - Physics Letters A, 2016 - Elsevier
We cast observable measure of quantum coherence as a resource to control the quantum
speed limit (QSL) for unitary evolutions. For non-unitary evolutions, QSL depends on that of …

Quantum speed limits for observables

B Mohan, AK Pati - Physical Review A, 2022 - APS
In the Schrödinger picture, the state of a quantum system evolves in time and the quantum
speed limit describes how fast the state of a quantum system evolves from an initial state to a …

Multiqubit systems: highly entangled states and entanglement distribution

A Borras, AR Plastino, J Batle, C Zander… - Journal of Physics A …, 2007 - iopscience.iop.org
A comparison is made of various searching procedures, based upon different entanglement
measures or entanglement indicators, for highly entangled multiqubits states. In particular …

Quantum dynamical speedup in a nonequilibrium environment

X Cai, Y Zheng - Physical Review A, 2017 - APS
We theoretically study the dynamical speedup of a quantum system in a nonequilibrium
environment. Based on the trace distance, we derive the generalized Margolus-Levitin and …

Speed limits on correlations in bipartite quantum systems

V Pandey, D Shrimali, B Mohan, S Das, AK Pati - Physical Review A, 2023 - APS
Quantum speed limit is bound on the minimum time a quantum system requires to evolve
from an initial state to final state under a given dynamical process. It sheds light on how fast …

Quantum-speed-limit time for multiqubit open systems

C Liu, ZY Xu, S Zhu - Physical Review A, 2015 - APS
Quantum-speed-limit (QSL) time captures the intrinsic minimal time interval for a quantum
system evolving from an initial state to a target state. In single qubit open systems, it was …

Generalised quantum speed limit for arbitrary time-continuous evolution

D Thakuria, A Srivastav, B Mohan… - Journal of Physics A …, 2023 - iopscience.iop.org
The quantum speed limit describes how quickly a quantum system can evolve in time from
an initial state to a final state under a given dynamics. Here, we derive a generalised …
