Topological quantum optics using atom-like emitter arrays coupled to photonic crystals
Janos Perczel, Johannes Borregaard, Darrick E. Chang +2
We propose a nanophotonic platform for topological quantum optics. Our system is composed of a two-dimensional lattice of non-linear quantum emitters with optical transitions embed…
Quantum-Assisted Telescope Arrays
Emil T. Khabiboulline, Johannes Borregaard, Kristiaan De Greve +1
Quantum networks provide a platform for astronomical interferometers capable of imaging faint stellar objects. In a recent work [arXiv:1809.01659], we presented a protocol that cir…
Optical Interferometry with Quantum Networks
Emil T. Khabiboulline, Johannes Borregaard, Kristiaan De Greve +1
We propose a method for optical interferometry in telescope arrays assisted by quantum networks. In our approach, the quantum state of incoming photons along with an arrival time i…
Photonic Band Structure of Two-dimensional Atomic Lattices
Janos Perczel, Johannes Borregaard, Darrick E. Chang +4
Two-dimensional atomic arrays exhibit a number of intriguing quantum optical phenomena, including subradiance, nearly perfect reflection of radiation and long-lived topological edg…
One- and two-axis squeezing of atomic ensembles in optical cavities
Johannes Borregaard, Emily D. Davis, Greg S. Bentsen +2
The strong light-matter coupling attainable in optical cavities enables the generation of highly squeezed states of atomic ensembles. It was shown in [Phys. Rev. A 66, 022314 (2002…
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…
