High-efficiency WSi superconducting nanowire single-photon detectors operating at 2.5 K

September 24, 2014
Author(s)
Varun B. Verma, Boris Korzh, Felix Bussieres, Robert D. Horansky, Adriana E. Lita, Francesco Marsili, Hugo Zbinden, Richard P. Mirin, Sae Woo Nam
We demonstrate that superconducting nanowire single photon detectors (SNSPDs) fabricated from amorphous WSi may be operated with > 75 % system detection efficiency at a temperature approaching seventy percent of the superconducting transition temperature

Mutual Cross Modulation of Two Laser Beams at the Individual-Photon Level

September 12, 2014
Author(s)
Michael Gullans, Kristin M. Beck, Qian Lin, M D. Lukin, Vladan Vuletic, Wenlan Chen
The realization of deterministic photon-photon interactions is a long-standing goal in optical science. Using an atomic ensemble inside a cavity, we demonstrate the mutual cross modulation of two continuous light beams at the level of individual photons

Photon-number uncertainty in a superconducting transition-edge sensor beyond resolved-photon-number determination

September 10, 2014
Author(s)
Zachary H. Levine, Boris L. Glebov, Alan L. Migdall, Thomas Gerrits, Brice R. Calkins, Adriana E. Lita, Sae Woo Nam
As part of an effort to extend fundamental single-photon measurements into the macroscopic regime, we explore how best to assign photon-number uncertainties to output waveforms of a superconducting Transition Edge Sensor (TES) and how those assignments

Sub-wavelength interference of thermal light with photon-number resolving detection

September 10, 2014
Author(s)
Yanhua (. Zhai, Francisco E. Becerra Chavez, Jingyun Fan, Alan L. Migdall
We examine the spatial correlation of thermal-light diffracted through a double-slit using photon-number-resolved detection to directly measure high-order correlations. We observe sinusoidal modulations of the spatial coherence in the diffracted light

Environment-assisted quantum control of a solid state spin via 2-color coherent dark states

September 7, 2014
Author(s)
Jacob M. Taylor, Jack Hansom, Carsten Schulte, Claire Le Gall, Clemens Matthiesen, Edmund Clarke, Maxime Hugues, Mete Atature
Semiconductor quantum dots (QDs) offer an efficient and scalable interface between single spins and optical photons. However, the solid-state environment of the QD represents an inherent source of noise, generally considered detrimental to coherent control

BQP-completeness of Scattering in Scalar Quantum Field Theory

September 1, 2014
Author(s)
Stephen P. Jordan, Keith S. Lee, John Preskill
Recent work has shown that quantum computers can in polynomial time compute scattering probabilities in massive quantum field theories. One can translate this task into a corresponding formal problem in computational complexity theory. Here, we establish

Photonic-assisted Endoscopic Analysis of Guided W-band Pulses

August 24, 2014
Author(s)
Jeffrey A. Jargon, DongJoon Lee, JaeYong Kwon
We present a photonic-assisted time-domain measurement technique for exploring millimeter-wave propagation through a W-band waveguide. The electric fields, guided inside a rectangular waveguide, are sampled using a sub-millimeter-scale electro-optic probe
