High-fidelity entangled photon pairs from a quantum-dot-based single-photon source
Malwina A. Marczak, Spencer J. Johnson, Mark R. Hogg +8
Entangled photon pairs are a ubiquitous resource in quantum technologies, used in quantum key distribution and quantum networking as well as fundamental tests of non-locality. For…
High-quality single photons from cavity-enhanced biexciton-to-exciton transition
Nils Heinisch, Francesco Salusti, Mark R. Hogg +7
Resonant laser excitation of a two-level system with subsequent single-photon emission can be used to generate single photons with high indistinguishability or Hong-Ou-Mandel (HOM)…
Four-Photon Interference with a High-Efficiency Quantum Dot Source
Alistair J. Brash, Luke Brunswick, Mark R. Hogg +6
While two-photon Hong-Ou-Mandel interference visibility has become a standard metric for single-photon sources, many optical quantum technologies require the generation and manipul…
Indistinguishable photons from a two-photon cascade
Timon L. Baltisberger, Francesco Salusti, Mark R. Hogg +7
Decay of a four-level diamond scheme via a cascade is a potential source of entangled photon pairs. A solid-state implementation is the biexciton cascade in a semiconductor quantum…
Towards quantitative understanding of quantum dot ensemble capacitance-voltage spectroscopy
Nico F. Brosda, Phil J. Badura, Ä°smail BölükbaÅı +6
Inhomogeneous ensembles of quantum dots (QDs) coupled to a charge reservoir are widely studied by using, e.g., electrical methods like capacitance-voltage spectroscopy. We present…
