High-efficiency entanglement of microwave fields in cavity opto-magnomechanical systems

K Di, S Tan, L Wang, A Cheng, X Wang, Y Liu, J Du - Optics Express, 2023 - opg.optica.org
We demonstrate a scheme to realize high-efficiency entanglement of two microwave fields in
a dual opto-magnomechanical system. The magnon mode simultaneously couples with the …

Scheme for realizing quantum dense coding via entanglement swapping

N Meher - Journal of Physics B: Atomic, Molecular and Optical …, 2020 - iopscience.iop.org
Quantum dense coding is a protocol for transmitting two classical bits of information from a
sender (Alice) to a remote receiver (Bob) by sending only one quantum bit (qubit). In this …

Non-Markovian entanglement transfer to distant atoms in a coupled superconducting resonator

Q Mu, P Lin - Chinese Physics B, 2020 - iopscience.iop.org
We investigate the non-Markovian effects on the entanglement transfer to the distant non-
interacting atom qubits, which are embedded in a coupled superconducting resonator. The …

The Rayleigh–Lorentz invariant for superconducting resonators and optimal adiabatic qubit-information detection

JR Choi - Scientific Reports, 2021 - nature.com
Dynamical properties of a resonator can be analyzed using the Rayleigh–Lorentz invariant
which is not an exact constant but varies more or less over time depending on variations of …
