Practical implementation of a test of event-based corpuscular model as an alternative to quantum mechanics

May 8, 2013
Author(s)
Sergey V. Polyakov, Alan L. Migdall, Ivo P. Degiovanni, Fabrizio Piacentini, Giorgio Brida, Marco Genovese, Paola Traina
We describe in detail the first experimental test that distinguishes between an event-based corpuscular model of the interaction of photons with matter and quantum mechanics. The test looks at the interference that results as a single photon passes through

Simultaneous Spin-Charge Relaxation in Double Quantum Dots

May 8, 2013
Author(s)
Vanita Srinivasa, Katja C. Nowack, Mohammad Shafiei, Lieven M. Vandersypen, Jacob M. Taylor
We investigate phonon-induced spin and charge relaxation mediated by spin-orbit and hyper- fine interactions for a single electron confined within a double quantum dot. A simple toy model incorporating both direct decay to the ground state of the double

Fast, Optically Controlled Kerr Phase Shifter for Digital Signal Processing

April 18, 2013
Author(s)
Runbing Li, Lu Deng, Edward W. Hagley, Joshua Bienfang, Zachary H. Levine, Marvin G. Payne
We demonstrate an optically controlled Kerr phase shifter using a room-temperature Rb85 vapor operating in a Raman gain scheme. Phase shifts from zero to 𝜋 relative to an unshifted reference wave are observed, and gated operations are demonstrated. We

Bell violation using entangled photons without the fair-sampling assumption

April 14, 2013
Author(s)
Marissa Giustina, Alexandra Mech, Sven Ramelow, Bernhard Wittman, Johannes Keffler, Joern Beyer, Adriana Lita, Thomas Gerrits, Sae Woo Nam, Rupert Ursin, Anton Zeilinger, Brice R. Calkins
The violation of a Bell inequality is an experimental observation that forces the abandonment of a local realistic viewpoint - namely, one in which physical properties are (probabilistically) defined before and independently of measurement, and in which no

Reducing noise in single-photon frequency conversion

April 10, 2013
Author(s)
Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Yong-Su Kim, Martin M. Fejer, Xiao Tang
We demonstrate low-noise and efficient frequency conversion using sum-frequency mixing in a periodically poled LiNbO3 (PPLN) waveguide. Using a 1556 nm pump, 1302 nm photons are efficiently converted to 709 nm photons. We obtain 70% conversion efficiency

Arbitrary waveform generator for quantum information processing with trapped ions

March 20, 2013
Author(s)
Ryan S. Bowler, Ulrich J. Warring, Joseph W. Britton, J. M. Amini
Ions confined in a multi-electrode trap design have been proposed as a possible basis for quantum information processing. This scheme involves transporting ions between spatially distinct locations using time varying electric potentials combined with laser

Highly efficient heralding of entangled single photons

March 11, 2013
Author(s)
Sven Ramelow, Alexandra Mech, Marissa Giustina, Simon Groeblacher, Witlef Wieczorek, Adriana Lita, Brice R. Calkins, Thomas Gerrits, Sae Woo Nam, Anton Zeilinger, Rupert Ursin
Single photons are an important prerequisite for a broad spectrum of quantum optical applications. We experimentally demonstrate a heralded single-photon source based on spontaneous parametric down- conversion in collinear bulk optics, and fiber-coupled

Effect of atomic coherence on "temporal cloaking" in atomic vapors

February 27, 2013
Author(s)
Runbing Li, Lu Deng, Edward W. Hagley, Joshua C. Bienfang, M G. Payne, Mo-Lin Ge
We discuss a different scheme to achieve temporal cloaking in warm atomic vapors. Instead of creating a temporal-spatial window in a patched broadband short optical pulse using static differential dispersion of an optical fiber, we create a temporal
