The Jaynes–Cummings model plays an important role in quantum entanglement and state measurements.Here,we discuss how to realize it in a waveguide-mediated interaction system,which comprises a giant atom and a resonat...

Using the measure of interference defined in this paper, we investigate the quantum phase transition of one-dimensional Ising chains. We find that thermal fluctuations affect the interference more strongly at the crit...

We investigate the interference of a kicked harmonic oscillator in phase space.With the measure of interference defined in Lee and Jeong[Phys.Rev.Lett.106(2011)220401],we show that interference increases more rapidly ...
The interference has been measured by the visibility in two-level systems, which, however, does not work for multi-level systems. We generalize a measure of the interference based on decoherence process, consistent wi...

We describe a scheme for the generation of macroscopic quantum-interference states for a collection of trapped ions by a single geometric phase operation. In the scheme the vibrational mode is displaced along a circle...
We study the mass neutrino interference phase in Schwarzschild-de Sitter space time along the null trajectory and the geodesic line and obtain the effects of cosmological constant A on the neutrino oscillation. Firstl...

In this paper, a scheme is proposed to create the entanglement of two superconducting quantum-interference devices (SQUIDs) and implement a two-quhit quantum phase gate between two SQUIDs in cavity. The scheme only ...
