Autoheterodyne characterization of narrow-band photon pairs
Prakash, Vindhiya; Sierant, Aleksandra; Mitchell, Morgan W. (American Institute of Physics (AIP), 2021-07-19)
Article
Open AccessWe describe a technique to measure photon pair joint spectra by detecting the time-correlation beat note when nondegenerate photon pairs interfere at a beam splitter. The technique implements a temporal analog of the ... -
Long-term laser frequency stabilization using fiber interferometers
Kong, Jia; Lucivero, Vito Giovanni; Jiménez-Martínez, Ricardo; Mitchell, Morgan W. (AIP, 2015-07-09)
Article
Open AccessWe report long-term laser frequency stabilization using only the target laser and a pair of 5 m fiber interferometers, one as a frequency reference and the second as a sensitive thermometer to stabilize the frequency ... -
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres
Hensen, B.; Bernien, H.; Dréau, A. E.; Reiserer, A.; Kalb, N.; Blok, M. S.; Ruitenberg, J.; Vermeulen, R. F. L.; Schouten, R. N.; Abellán, Carlos, 1990-; Amaya, W.; Pruneri, P.; Mitchell, Morgan W.; Markham, M.; Twitchen, D. J.; Elkouss, D.; Wehner, S.; Taminiau, T. H.; Hanson, R. (Nature Publishing Group, 2015-10-21)
Article
Restricted access - publisher's policyMore than 50 years ago1, John Bell proved that no theory of nature that obeys locality and realism2 can reproduce all the predictions of quantum theory: in any local-realist theory, the correlations between outcomes of ... -
Macroscopic Quantum State Analyzed Particle by Particle
Beduini, Federica A.; Zielińska, Joanna Ada; Lucivero, Vito G.; Icaza Astiz, Yannick A. de; Mitchell, Morgan W. (ACS Publications, 2015-03-27)
Article
Open AccessMacroscopic quantum phenomena, e.g., superconductivity and squeezing, are believed to result from entanglement of macroscopic numbers of particles. We report the first direct study of this kind of entanglement: we use ... -
Manipulating and measuring single atoms in the Maltese cross geometry
Bianchet, Lorena Cecilia; Natalia, Alves; Zarraoa Sardón, Laura; Bruno, Natalia; Mitchell, Morgan W. (2021-09-06)
Article
Open AccessBackground: Optical microtraps at the focus of high numerical aperture (high-NA) imaging systems enable efficient collection, trapping, detection and manipulation of individual neutral atoms for quantum technology and ... -
Passive Decoy-State Quantum Key Distribution with Coherent Light
Curty, Marcos; Jofre Cruanyes, Marc; Pruneri, Valerio; Mitchell, Morgan W. (MDPI, 2015-06-12)
Article
Open AccessSignal state preparation in quantum key distribution schemes can be realized using either an active or a passive source. Passive sources might be valuable in some scenarios; for instance, in those experimental setups ... -

Phase-stable source of polarization-entangled photons in a linear double-pass configuration
Steinlechner, F.; Ramelow, Sven; Jofre, Martí; Gilaberte, Marta; Jennewein, Thomas; Pérez Torres, Juan; Mitchell, Morgan W.; Pruneri, Valerio (2013-05)
Article
Open AccessWe demonstrate a compact, robust, and highly efficient source of polarization-entangled photons, based on linear bi-directional down-conversion in a novel ‘folded sandwich’ configuration. Bi-directionally pumping a single ... -
Quantum atom-light interfaces in the Gaussian description for spin-1 systems
Colangelo, Giorgio; Sewell, Robert J.; Behbood, Naeimeh; Ciurana, Ferran Martin; Triginer Cahelles, Joaquim; Mitchell, Morgan W. (2013-10)
Article
Open AccessWe extend the covariance matrix description of atom–light quantum interfaces, originally developed for real and effective spin-1/2 atoms, to include ‘spin alignment’ degrees of freedom. This allows accurate modelling ... -
Strong experimental guarantees in ultrafast quantum random number generation
Mitchell, Morgan W.; Abellán, Carlos, 1990-; Amaya, Waldimar (American Physical Society, 2015-01-12)
Article
Open AccessWe describe a methodology and standard of proof for experimental claims of quantum random-number generation (QRNG), analogous to well-established methods from precision measurement. For appropriately constructed physical ...
