We present an analytical and numerical analysis of the particle creation in a cavity ended with two SQUIDs, both subjected to time dependent magnetic fields. In the linear and lossless regime, the problem can be modeled by a free quantum field in $1+1$ dimensions, in the presence of boundary conditions that involve a time dependent linear combination of the field and its spatial and time derivatives. We consider a situation in which the boundary conditions at both ends are periodic functions of…

Asymmetric quantum correlations in the dynamical Casimir effect

TLDR
It is shown that steering from Bob to Alice is more difficult than steering from Alice to Bob and regions that represent states that, although entangled, cannot be used for teleporting coherent states; however, the steerable states are appropriate for quantum teleportation.

Decoherence of Einstein-Podolsky-Rosen steering and the teleportation fidelity in the dynamical Casimir effect

TLDR
It is observed that a high temperature of the environments results in a faster decoherence of steering and fidelity, and it shows that it is important to choose the suitable asymmetric noise channel to protect the directional Einstein–Podolsky–Rosen steering.
