Non-classicality tests and entanglement witnesses for macroscopic mechanical superposition states
Oleg Gittsovich, Tobias Moroder, Ali Asadian +2
We describe a set of measurement protocols for performing non-classicality tests and the verification of entangled superposition states of macroscopic continuous variable systems,…
"Magic" radio-frequency dressing for trapped atomic microwave clocks
Georgy A. Kazakov, Thorsten Schumm
It has been proposed to use magnetically trapped atomic ensembles to enhance the interrogation time in microwave clocks. To mitigate the perturbing effects of the magnetic trap, ne…
Photon exchange and entanglement formation during the transmission through a rectangular quantum barrier
Georg Sulyok, Katharina Durstberger-Rennhofer, Johann Summhammer
When a quantum particle traverses a rectangular potential created by a quantum field both photon exchange and entanglement between particle and field take place. We present analyti…
Non-Markovian dynamics of a single-mode cavity strongly coupled to an inhomogeneously broadened spin ensemble
Dmitry O. Krimer, Stefan Putz, Johannes Majer +1
We study the dynamics of a spin ensemble strongly coupled to a single-mode resonator driven by external pulses. When the mean frequency of the spin ensemble is in resonance with th…
Two-dimensional Lattice Gauge Theories with Superconducting Quantum Circuits
D. Marcos, P. Widmer, E. Rico +4
A quantum simulator of U(1) lattice gauge theories can be implemented with superconducting circuits. This allows the investigation of confined and deconfined phases in quantum link…
Physical aspects of oracles for randomness, and Hadamard's conjecture
Karl Svozil
We analyze the physical aspects and origins of currently proposed oracles for (absolute) randomness.
