Phase-diffusion dynamics in weakly coupled Bose-Einstein condensates
Erez Boukobza, Maya Chuchem, Doron Cohen +1
We study the phase-sensitivity of collisional phase-diffusion between weakly coupled Bose-Einstein condensates, using a semiclassical picture of the two-mode Bose-Hubbard model. Wh…
Efficient compilation of quantum circuits using multi-qubit gates
Jonathan Nemirovsky, Maya Chuchem, Yotam Shapira
As quantum processors grow in scale and reliability, the need for efficient quantum gate decomposition of circuits to a set of specific available gates, becomes ever more critical.…
Restricted quantum-classical correspondence and counting statistics for a coherent transition
Maya Chuchem, Doron Cohen
The conventional probabilistic point of view implies that if a particle has a probability to make a transition from one site to another site, then the average transport should…
Occupation Statistics of a BEC for a Driven Landau-Zener Crossing
Katrina Smith-Mannschott, Maya Chuchem, Moritz Hiller +2
We consider an atomic Bose-Einstein condensate (BEC) loaded in a biased double-well trap with tunneling rate and inter-atomic interaction . The BEC is prepared such that all…
Non-adiabatic pumping in an oscillating-piston model
Maya Chuchem, Thomas Dittrich, Doron Cohen
We consider the prototypical "piston pump" operating on a ring, where a circulating current is induced by means of an AC driving. This can be regarded as a generalized Fermi-Ulam m…
Quantum dynamics in the bosonic Josephson junction
Maya Chuchem, Katrina Smith-Mannschott, Moritz Hiller +3
We employ a semiclassical picture to study dynamics in a bosonic Josephson junction with various initial conditions. Phase-diffusion of coherent preparations in the Josephson regim…
Quantum transport and counting statistics in closed systems
Maya Chuchem, Doron Cohen
A current can be induced in a closed device by changing control parameters. The amount of particles that are transported via a path of motion, is characterized by its expectati…
Phase gadget compilation of quantum circuits using multiqubit gates
Jonathan Nemirovsky, Maya Chuchem, Lee Peleg +3
Quantum circuit synthesis and compilation are critical components in the quantum computing stack, both for contemporary quantum systems, where efficient use of limited resources is…
Counting statistics in multiple path geometries and the fluctuations of the integrated current in a quantum stirring device
Maya Chuchem, Doron Cohen
The amount of particles that are transported via a path of motion is characterized by its expectation value and by its variance . We analyze what happens if a par…
