MQHOA algorithm with energy level stabilizing process

Tongxin xuebao, 2016
An improved multi-scale quantum harmonic oscillator algorithm (MQHOA) with energy level stabilizing process was proposed analogizing to quantum harmonic oscillator's wave function.

Non-classical correlations beyond Bell’s inequality violation in qubit-pairs with an intrinsic noise

Results in Physics, 2019
In this paper, we analytically explore two qubits interacting with a coherent harmonic oscillator field under intrinsic noise. The interaction of the uncorrelated two qubits with a harmonic oscillator initially in the superposition of coherent states ...

A New Two-Parameter Family of Potentials with a Tunable Ground State

, 2011
In a previous paper we solved a countably infinite family of one-dimensional Schr\"odinger equations by showing that they were supersymmetric partner potentials of the standard quantum harmonic oscillator. In this work we extend these results to find the

Quantum Kicked Dynamics and Classical Diffusion

, 1997
We consider the quantum counterpart of the kicked harmonic oscillator showing that it undergoes the effect of delocalization in momentum when the classical diffusional threshold is obeyed.

Controllability of Quantum Harmonic Oscillators [PDF]

IEEE Transactions on Automatic Control, 2004
It is proven in a previous paper that any modal approximation of the one-dimensional quantum harmonic oscillator is controllable. We prove here that, contrary to such finite-dimensional approximations, the original infinite-dimensional system is not controllable: Its controllable part is of dimension 2 and corresponds to the dynamics of the average ...

Harmonic Oscillator SUSY Partners and Evolution Loops

Symmetry, Integrability and Geometry: Methods and Applications, 2012
Supersymmetric quantum mechanics is a powerful tool for generating exactly solvable potentials departing from a given initial one. If applied to the harmonic oscillator, a family of Hamiltonians ruled by polynomial Heisenberg algebras is obtained.

d-Dimensional generalization of the point canonical transformation for a quantum particle with position-dependent mass

, 2006
The d-dimensional generalization of the point canonical transformation for a quantum particle endowed with a position-dependent mass in Schrodinger equation is described. Illustrative examples including; the harmonic oscillator, Coulomb, spiked harmonic,

Deterministic nonlinear phase gates induced by a single qubit

New Journal of Physics, 2018
We propose deterministic realizations of nonlinear phase gates by repeating a finite sequence of non-commuting Rabi interactions between a harmonic oscillator and only a single two-level ancillary qubit.

Multipartite Entanglement Generation in a Structured Environment

Entropy, 2020
In this paper, we investigate the entanglement generation of n-qubit states in a model consisting of n independent qubits, each coupled to a harmonic oscillator which is in turn coupled to a bath of N additional harmonic oscillators with nearest-neighbor

GENERALIZED HEISENBERG RELATION AND QUANTUM HARMONIC OSCILLATORS [PDF]

International Journal of Modern Physics A, 2006
We study the consequences of the generalized Heisenberg uncertainty relation which admits a minimal uncertainty in length such as the case in a theory of quantum gravity. In particular, the theory of quantum harmonic oscillators arising from such a generalized uncertainty relation is examined.
