Non-hermitian quantum systems and time-optimal quantum evolution
(2009)
Recently, Bender et al. have considered the quantum brachistochrone problem for the non-Hermitian PT -symmetric quantum system and have shown that the optimal time evolution required to transform a given initial state ?i? ...

Role of initial conditions in the dynamics of quantum glassy systems
(IOP Publishing, 2019-02-25)
We set the formalism to study the way in which the choice of canonical equilibrium initial conditions affect the real-time dynamics of quantum disordered models. We use a path integral formulation on a time contour with ...
Quantum-speed-limit bounds in an open quantum evolution
(American Physical Society, 2016-11)
ABSTRACTQuantum mechanics dictates bounds for the minimal evolution time between predetermined initial and final states. Several of these quantum-speed-limit (QSL) bounds were derived for nonunitary dynamics using different ...
Emergent dynamics from entangled mixed states
(American Physical Society, 2020-11-20)
Entanglement is at the core of quantum physics, playing a central role in quantum phenomena involving composite systems. According to the timeless picture of quantum dynamics, entanglement may also be essential for ...
Remanent quantum correlations in dissipative qubits
(Elsevier Science, 2013-08-02)
Starting from the exact evolution of a Markovian dissipative quantum walk, a non-Markovian decoherence of two qubits interacting with a phonon thermal bath has been investigated analytically using quantum information tools. ...
Quantum metrology in a non-Markovian quantum evolution
(American Physical Society, 2020-08)
The problem of quantum metrology in the context of a particular non-Markovian quantum evolution is explored. We study the dynamics of the quantum Fisher information (QFI) of a composite quantum probe coupled to a Lorentzian ...
