Kinetic Spin Decoherence in a Gravitational Field
Yue Dai, Yu Shi
We consider a wave packet of a spin-1/2 particle in a gravitational field, the effect of which can be described in terms of a succession of local inertial frames. It is shown that…
Decoherence and disentanglement of qubits detecting scalar fields in an expanded universe
Yujie Li, Yue Dai, Yu Shi
We consider Unruh-Wald qubit detector model adopted for the far future region of an exactly solvable 1+1 dimensional scalar field theory in a Robertson-Walker expanding spacetime.…
Quantum entanglement in three accelerating qubits coupled to scalar field
Yue Dai, Zhejun Shen, Yu Shi
We consider quantum entanglement of three accelerating qubits, each of which is locally coupled with a real scalar field, without causal influence among the qubits or among the fie…
Killing quantum entanglement by acceleration or a black hole
Yue Dai, Zhejun Shen, Yu Shi
We consider two entangled accelerating qubits coupled with real scalar fields, each described by the Unruh-Wald model. It is demonstrated that because of the Unruh effect, the bipa…
