Sequential state discrimination with quantum correlation
The sequential unambiguous state discrimination (SSD) of two states prepared in arbitrary prior probabilities is studied and compared with three strategies that allow classical communication. The deviation fro...

Motion of Charged Particle in Electric and Magnetic Fields in 3D Noncommutative Spaces and Related Problems
In three-dimensional noncommutative phase space, the energy spectrum and wave functions for the motion of a charged particle in a magnetic field are derived. Due to the momentum–momentum noncommutativity, the ...

Quantum-classical correspondence of the Dirac equation with a scalar-like potential
Quantum matrix elements of the coordinate, momentum and the velocity operator for a spin-1/2 particle moving in a scalar-like potential are calculated. In the large quantum number limit, these matrix elements ...

Berry phases in the three-level atoms driven by quantized light fields
A theoretical analysis of Berry’s phases is given for the three-level atoms interacting with external one-mode and two-mode quantized light fields. Three main results are obtained: (i) There is a Berry phase w...

Electron–Phonon Interaction and Quantum Fluctuations in the Time-Dependent Damped Capacitance-Coupled Electric Circuit
Starting from the electron–phonon interaction, the time-dependent capacitance-coupled electric circuit is quantized. Quantum fluctuations derived by this method are different from former ones.

Quantum—classical correspondence of the time-dependent linear potential
Using the trial-function method, the general solution of the Schrödinger equation for the time-dependent linear potential is obtained. Based on the Heisenberg correspondence principle, the solution of the clas...

Forced Time-Dependent Harmonic Oscillator in a Static Magnetic Field: Exact Quantum and Classical Solutions
Exact wave functions of the forced time-dependent two-dimensional harmonic oscillator in a static magnetic field are derived by unitary transformation. The geometrical phase induced by the driving force is the...
