Magnetic noise spectrum measurement by an atom laser in gravity
O. Kálmán, Z. Darázs, F. Brennecke +1
Bose-Einstein condensates of ultracold atoms can be used to sense fluctuations of the magnetic field by means of transitions into untrapped hyperfine states. It has been shown rece…
Double self-Kerr scheme for optical Schrödinger-cat state preparation
P. Adam, Z. Darázs, T. Kiss +1
We propose a scheme to prepare optical Schrödinger-cat states in a traveling wave setting. Two states are similarly prepared via the self-Kerr effect and after mixing them, one mod…
Conditional generation of optical Schrödinger cat states
P. Adam, T. Kiss, Z. Darázs +1
Given a source of two coherent state superpositions with small separation in a traveling wave optical setting, we show that by interference and balanced homodyne measurement it is…
Time evolution of continuous-time quantum walks on dynamical percolation graphs
Zoltán Darázs, Tamás Kiss
We study the time evolution of continuous-time quantum walks on randomly changing graphs. At certain moments edges of the graph appear or disappear with a given probability. We foc…
Pólya number of continuous-time quantum walks
Z. Darázs, T. Kiss
We propose a definition for the Pólya number of continuous-time quantum walks to characterize their recurrence properties. The definition involves a series of measurements on the s…
