An entanglement-aware quantum computer simulation algorithm
Maxime Oliva
The advent of quantum computers promises exponential speed ups in the execution of various computational tasks. While their capabilities are hindered by quantum decoherence, they c…
Quantum Kerr oscillators' evolution in phase space: Wigner current, symmetries, shear suppression and special states
Maxime Oliva, Ole Steuernagel
The creation of quantum coherences requires a system to be anharmonic. The simplest such continuous 1D quantum system is the Kerr oscillator. It has a number of interesting symmetr…
Dynamic shear suppression in quantum phase space
Maxime Oliva, Ole Steuernagel
Classical phase space flow is inviscid. Here we show that in quantum phase space Wigner's probability current J can be effectively viscous. This results in shear suppression in qua…
Structures far below sub-Planck scale in quantum phase-space through superoscillations
Maxime Oliva, Ole Steuernagel
In 2001, Zurek derived the generic minimum scale for the area of structures of Wigner's quantum phase distribution. Here we show by construction, using superoscillatory fun…
Comment on "Wigner phase space description of a Morse oscillator'' [J. Chem. Phys. 77, 4604 (1982)]
Dimitris Kakofengitis, Maxime Oliva, Ole Steuernagel
Comment on ``Wigner phase space description of a Morse oscillator''
Wigner's representation of quantum mechanics in integral form and its applications
Dimitris Kakofengitis, Maxime Oliva, Ole Steuernagel
We consider quantum phase-space dynamics using Wigner's representation of quantum mechanics. We stress the usefulness of the integral form for the description of Wigner's phase-spa…
Anharmonic quantum mechanical systems do not feature phase space trajectories
Maxime Oliva, Dimitris Kakofengitis, Ole Steuernagel
Phase space dynamics in classical mechanics is described by transport along trajectories. Anharmonic quantum mechanical systems do not allow for a trajectory-based description of t…
Superfluidity and collective oscillations of trapped Bose-Einstein condensates in a periodical potential
C. Trallero-Giner, V. Lopez-Richard, Y. Núñez-Fernández +2
Based on a unified theoretical treatment of the 1D Bogoliubov-de Genes equations, the superfluidity phenomenon of the Bose-Einstein condensates (BEC) loaded into trapped optical la…
