Schwinger effect of a relativistic boson entangled with a qubit
Yujie Li, Yu Shi
We use the concept of quantum entanglement to analyze the Schwinger effect on an entangled state of a qubit and a bosonic mode coupled with the electric field. As a consequence of…

Pairwise mode entanglement in Schwinger production of particle-antiparticle pairs in an electric field
Yujie Li, Yue Dai, Yu Shi
Quantum entanglement is the characteristic quantum correlation. Here we use this concept to analyze the quantum entanglement generated by Schwinger production of particle-antiparti…

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.…
