Quantum control of continuous systems via nonharmonic potential modulation
Piotr T. Grochowski, Hannes Pichler, Cindy A. Regal +1
We present a theoretical proposal for preparing and manipulating a state of a single continuous-variable degree of freedom confined to a nonharmonic potential. By utilizing optimal…
Wigner Analysis of Particle Dynamics and Decoherence in Wide Nonharmonic Potentials
Andreu Riera-Campeny, Marc Roda-Llordes, Piotr T. Grochowski +1
We derive an analytical expression of a Wigner function that approximately describes the time evolution of the one-dimensional motion of a particle in a nonharmonic potential. Our…
Numerical Simulation of Large-Scale Nonlinear Open Quantum Mechanics
Marc Roda-Llordes, Davide Candoli, Piotr T. Grochowski +5
We introduce a numerical method to simulate nonlinear open quantum dynamics of a particle in situations where its state undergoes significant expansion in phase space while generat…
Macroscopic Quantum Superpositions via Dynamics in a Wide Double-Well Potential
Marc Roda-Llordes, Andreu Riera-Campeny, Davide Candoli +2
We present an experimental proposal for the rapid preparation of the center of mass of a levitated particle in a macroscopic quantum state, that is a state delocalized over a lengt…
