Stochastic trajectories and excursions in a double quantum dot system
Guilherme Fiusa, Pedro E. Harunari, Alberto J. B. Rosal +2
We investigate the trajectory-level stochastic dynamics of a double quantum dot system using the formalism of stochastic excursions. An excursion is a sub-trajectory that begins wh…
Bosonic statistics enhance Maxwell's demon in photonic experiment
Malaquias Correa Anguita, Sara Marzban, William F. Braasch +4
Maxwell's demon elucidates the value of information in thermodynamics, using measurement and feedback: he evolves an equilibrated gas into a nonequilibrium state, from which one mi…
Analog quantum simulation of the Lipkin-Meshkov-Glick model in a transmon qudit
Elizabeth Champion, Annie Schwartz, Muhammad A. Ijaz +4
The simulation of large-scale quantum systems is one of the most sought-after applications of quantum computers. Of particular interest for near-term demonstrations of quantum comp…
Metrological approach to the emergence of classical objectivity
Anthony Kiely, Diana A. Chisholm, Akram Touil +3
We present a precise characterization of the onset of classicality that combines the formalism of quantum Darwinism with the tools from quantum metrology. We show that the quantum…
