Quantum speed limit for states with a bounded energy spectrum

G Ness, A Alberti, Y Sagi - Physical review letters, 2022 - APS
Quantum speed limits set the maximal pace of state evolution. Two well-known limits exist
for a unitary time-independent Hamiltonian: the Mandelstam-Tamm and Margolus-Levitin …

Quantum speed limits across the quantum-to-classical transition

B Shanahan, A Chenu, N Margolus, A Del Campo - Physical review letters, 2018 - APS
Quantum speed limits set an upper bound to the rate at which a quantum system can evolve.
Adopting a phase-space approach, we explore quantum speed limits across the quantum-to …

Spectral filtering induced by non-hermitian evolution with balanced gain and loss: Enhancing quantum chaos

J Cornelius, Z Xu, A Saxena, A Chenu, A Del Campo - Physical Review Letters, 2022 - APS
The dynamical signatures of quantum chaos in an isolated system are captured by the
spectral form factor, which exhibits as a function of time a dip, a ramp, and a plateau, with the …

At the limits of criticality-based quantum metrology: apparent super-Heisenberg scaling revisited

MM Rams, P Sierant, O Dutta, P Horodecki… - Physical Review X, 2018 - APS
We address the question of whether the super-Heisenberg scaling for quantum estimation is
indeed realizable. We unify the results of two approaches. In the first one, the original system …
