The processing of information and computation is undergoing a paradigmatic shift since the
realization of the enormous potential of quantum features to perform these tasks. Coupled …

The “Lewis-Riesenfeld phases” which play a crucial role in constructing shortcuts to
adiabaticity may be a resource for the implementation of quantum phase gates. By …

We propose a theoretical scheme for photon blockade in a cavity quantum electrodynamic
system consisting of an N-type atomic medium interacting with a single-mode Fabry-Pérot …

We present a way to realize an n-qubit controlled phase gate with superconducting quantum-
interference devices (SQUIDs) by coupling them to a superconducting resonator. In this …

A scheme is proposed to obtain three-qubit gates, such as quantum-phase gate and C 2-not
gate operations, in a cavity QED system where highly detuned cavity-field modes interact …

A scheme for implementing a three-qubit Toffoli gate with atoms sent through a microwave
cavity is proposed by choosing nonidentical coupling constants between the atoms and …

We study the entanglement properties of two three-level Rydberg atoms passing through a
single-mode cavity. The interaction of an atom with the cavity field allows the atom to make a …

Based on the quantum Zeno dynamics, we propose two approaches for directly
implementing a CNOT gate in a cavity QED system instead of constructing it from elementary …

Cavity-mediated two-qubit gates, for example between solid-state spins, are attractive for
quantum network applications. We propose three schemes to implement a controlled phase …

We investigate the dynamical evolution of the global quantum discord (GQD) and the von
Neumann entropy (VNE) of a moving two-, three-, and four two-level atomic system (TLS)(N …
