Enhancement of Sudden Death of Entanglement for Driven Qubits [PDF]
Journal of Low Temperature Physics, 2008 We study the recently discovered phenomena of sudden death of entanglement for a system of two qubits, each of them independently longitudinally damped by a reservoir and subjected to a continuous driving.

Sudden death of entanglement with a Hamiltonian ensemble assisted by auxiliary qubits [PDF]
Physical Review A, 2023 In this paper, we theoretically propose a method to simulate the longitudinal relaxation of a single qubit by coupling it to an auxiliary qubit. In order to mimic the finite-temperature relaxation, we utilize the Hamiltonian-ensemble approach [Kropf ...

Decoherence-free subspace and entanglement sudden death of multi-photon polarization states in fiber channels [PDF]
Communications in Theoretical Physics, 2022 The construction of quantum networks requires long-distance teleportation of multi-qubit entangled states. Here, we investigate the entanglement dynamics of GHZ and W states in fiber channels.

Sudden death of entanglement in fermionic systems under collective decoherence [PDF]
Journal of Physics A: Mathematical and Theoretical, 2020 We analyze the dynamics of entanglement due to decoherence in a system of two identical fermions with spin 3/2 interacting with a global bosonic environment.

Universality of sudden death of entanglement [PDF]
Quantum Information and Computation, 2011 We present a constructive argument to demonstrate the universality of the sudden death of entanglement in the case of two non-interacting qubits, each of which generically coupled to independent Markovian environments at zero temperature. Conditions for the occurrence of the abrupt disappearance of entanglement are determined and, most importantly ...

Physical Review Research, 2023 Entanglement is known to decay even in isolated systems, an effect attributed to spontaneous emission. This fragility of entanglement can be exacerbated by entanglement sudden death (ESD), where entanglement drops to zero abruptly within a finite time ...

Entanglement in nonlinear two-qibit Tavis — Cummings model
Вестник Самарского университета: Естественнонаучная серия, 2023 In this work, we have studied the dynamics of entanglement of two identical superconducting qubits resonantly interacting with the one-mode field of a coplanar microwave cavity without loss through single-photon transitions in the presence of third- and ...

Observation of entanglement sudden death and rebirth by controlling a solid-state spin bath [PDF]
Physical review B, 2018 Quantum entanglement, the essential resource for quantum information processing, has rich dynamics under different environments. Probing different entanglement dynamics typically requires exquisite control of complicated system-environment coupling in ...
