Entanglement witnesses from mutually unbiased measurements
Katarzyna Siudzińska, Dariusz Chruściński
A new family of positive, trace-preserving maps is introduced. It is defined using the mutually unbiased measurements, which generalize the notion of mutual unbiasedness of orthono…
How many mutually unbiased bases are needed to detect bound entangled states?
Joonwoo Bae, Anindita Bera, Dariusz Chruściński +2
From a practical perspective it is advantageous to develop methods that verify entanglement in quantum states with as few measurements as possible. In this paper we investigate the…
Thermodynamics and the quantum speed limit in the non-Markovian regime
Arpan Das, Anindita Bera, Sagnik Chakraborty +1
Quantum speed limit (QSL) for open quantum systems in the non-Markovian regime is analyzed. We provide a the lower bound for the time required to transform an initial state to a fi…
Eternally non-Markovian dynamics of a qubit interacting with a single-photon wavepacket
Anita Dąbrowska, Dariusz Chruściński, Sagnik Chakraborty +1
An evolution of a two-level system (qubit) interacting with a single-photon wave packet is analyzed. It is shown that a hierarchy of master equations gives rise to phase covariant…
How to design quantum-jump trajectories via distinct master equation representations
Dariusz Chruściński, Kimmo Luoma, Jyrki Piilo +1
Every open-system dynamics can be associated to infinitely many stochastic pictures, called unravelings, which have proved to be extremely useful in several contexts, both from the…
