Quantized recurrence time in iterated open quantum dynamics
P. Sinkovicz, Z. Kurucz, T. Kiss +1
The expected return time to the original state is a key concept characterizing systems obeying both classical or quantum dynamics. We consider iterated open quantum dynamical syste…
Parametric amplification of the mechanical vibrations of a suspended nanowire by magnetic coupling to a Bose-Einstein condensate
Z. Darázs, Z. Kurucz, O. Kálmán +3
We consider the possibility of parametric amplification of a mechanical vibration mode of a nanowire due to its interaction with a Bose-Einstein condensate (BEC) of ultracold atoms…
Spectroscopic properties of inhomogeneously broadened spin ensembles in a cavity
Z. Kurucz, J. H. Wesenberg, K. Mølmer
In large ensembles of identical atoms or spins, the interaction with a mode of the electromagnetic radiation field concentrates in a single superradiant degree of freedom with a co…
Dynamics of the collective modes of an inhomogeneous spin ensemble in a cavity
Janus H. Wesenberg, Zoltan Kurucz, Klaus Mølmer
We study the excitation dynamics of an inhomogeneously broadened spin ensemble coupled to a single cavity mode. The collective excitations of the spin ensemble can be described in…
Multilevel Holstein-Primakoff approximation and its application to atomic spin squeezing and ensemble quantum memories
Z. Kurucz, K. Mølmer
We show that an ensemble of identical d-level atoms can be efficiently described by d-1 collective oscillator degrees of freedom in the vicinity of a product state with all atoms i…
Qubit protection in nuclear-spin quantum dot memories
Z. Kurucz, M. W. Sørensen, J. M. Taylor +2
We present a mechanism to protect quantum information stored in an ensemble of nuclear spins in a semiconductor quantum dot. When the dot is charged the nuclei interact with the sp…
