Genuine entanglement under squeezed generalized amplitude damping ch.nnels with.memory

Ch.nese Ph.sics B 2024年第2期33卷 158-163页

作者： Mazh.r ali Department of Electrical Engineering Faculty of EngineeringIslamic University MadinahMadinah 107Saudi Arabia

We study genuine entanglement among th.ee qubits undergoing a noisy process th.t includes dissipation, squeezing,and decoh.rence. We obtain a general solution and analyze th. asymptotic quantum states. We find th.t most of th.se asymptotic states can be genuinely entangled depending upon th. parameters of th. ch.nnel, memory parameter, and th. parameters of th. initial states. We study Greenberger–h.rne–Zeilinger(Gh.) states and W states, mixed with.wh.te noise,and determine th. conditions for th.m to be genuinely entangled at infinity. We find th.t for th.se mixtures, it is possible to start with.a bi-separable state(with.a specific mixture of wh.te noise) and end with.genuine entangled states. h.wever, th. memory parameter μ must be very h.gh. We find th.t in contrast to th. two-qubit case, none of th. th.ee-qubit asymptotic states for n → ∞ are genuinely entangled.
