Entangled state testing in the quantum Byzantine agreement
网络与信息安全学报, 2016 In distributed computing,Byzantine agreement is a practical method to solve its fault-tolerance problem.There is a variation of the Byzantine agreement which is called detectable Byzantine agreement.This kind of protocol is unsolvable by classical means ...

Shortcut to Equilibration of an Open Quantum System. [PDF]
Physical Review Letters, 2018 We present a procedure to accelerate the relaxation of an open quantum system towards its equilibrium state. The control protocol, termed the shortcut to equilibration, is obtained by reverse-engineering the nonadiabatic master equation.

Direct entropy measurement in a mesoscopic quantum system [PDF]
Nature Physics, 2018 The entropy of an electronic system offers important insights into the nature of its quantum mechanical ground state. This is particularly valuable in cases where the state is difficult to identify by conventional experimental probes, such as conductance.

Complexity in quantum systems [PDF]
Physical Review E, 1994 We discuss the behavior of a quantum 1/2 spin coupled to a time dependent magnetic field, which can be quasiperiodic or random. For a quasiperiodic field, the time evolution of the system on a coarse grained space has autocorrelation, which does not decay, and positive topological entropy. The information complexity diverges as a stretched exponential,

Robust control of quantum systems by quantum systems [PDF]
Physical Review A, 2021 Quantum systems can be controlled by other quantum systems in a reversible way, without any information leaking to the outside of the system-controller compound. Such coherent quantum control is deterministic, is less noisy than measurement-based feedback control, and has potential applications in a variety of quantum technologies, including quantum ...

Experimental test of exchange fluctuation relations in an open quantum system [PDF]
, 2019 Elucidating the energy transfer between a quantum system and a reservoir is a central issue in quantum non-equilibrium thermodynamics, which could provide novel tools to engineer quantum-enhanced heat engines.

Ergodic dynamics and thermalization in an isolated quantum system [PDF]
Nature Physics, 2016 The realization of a quantum kicked top provides evidence for ergodic dynamics and thermalization in a small quantum system consisting of three superconducting qubits.

Open fermionic quantum systems [PDF]
Physical Review B, 1993 A method to treat a quantum system in interaction with a fermionic reservoir is presented. Its most important feature is that the dynamics of the exchange of particles between the system and the reservoir is explicitly included via an effective interaction term in the Hamiltonian. This feature gives rise to fluctuations in the total number of particles
