Noise Spectroscopy with a Quantum Gas
P. Federsel, C. Rogulj, T. Menold +4
We report on the spectral analysis and the local measurement of intensity correlations of microwave fields using ultra cold quantum gases. The fluctuations of the electromagnetic f…
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…
