Elementary test for non-classicality based on measurements of position and momentum
Luca Fresta, Johannes Borregaard, Anders S. Sørensen
We generalise a non-classicality test described by Kot et al. [Phys. Rev. Lett. 108, 233601 (2010)], which can be used to rule out any classical description of a physical system. T…
Photonic Controlled-Phase Gates Through Rydberg Blockade in Optical Cavities
Sumanta Das, Andrey Grankin, Ivan Iakoupov +7
We propose a novel scheme for high fidelity photonic controlled phase gates using Rydberg blockade in an ensemble of atoms in an optical cavity. The gate operation is obtained by f…
Long-distance entanglement distribution using individual atoms in optical cavities
Johannes Borregaard, Peter Kómár, Eric M. Kessler +2
Individual atoms in optical cavities can provide an efficient interface between stationary qubits and flying qubits (photons), which is an essentiel building block for quantum comm…
Heralded quantum gates with integrated error detection in optical cavities
J. Borregaard, P. Kómár, E. M. Kessler +2
We propose and analyze heralded quantum gates between qubits in optical cavities. They employ an auxiliary qubit to report if a successful gate occurred. In this manner, the errors…
