Superconducting nanowire single photon detectors fabricated from an amorphous Mo0.75Ge0.25 thin-film

July 15, 2014
Author(s)
Varun B. Verma, Adriana E. Lita, Michael R. Vissers, Francesco Marsili, David P. Pappas, Richard P. Mirin, Sae Woo Nam
We present the characteristics of superconducting nanowire single photon detectors (SNSPDs) fabricated from amorphous Mo0.75Ge0.25 thin -films. Fabricated devices show a saturation of the internal detection efficiency at temperatures below 1 K, with system

A classical channel model for gravitational decoherence

June 26, 2014
Author(s)
Jacob M. Taylor, Dvir Kafri, G J. Milburn
We show that, by treating the gravitational interaction between two mechanical resonators as a classical measurement channel, a gravitational decoherence model results that is equivalent to a model first proposed by Diosi. The resulting decoherence model

LDPC Error Correction for Gb/s QKD

June 24, 2014
Author(s)
Alan Mink, Anastase Nakassis
Low Density Parity Check (LDPC) error correction is a one-way algorithm that has become popular for quantum key distribution (QKD) post-processing. Graphic processing units (GPUs) provide an interesting attached platform that may deliver Gb/s error

Photon-Efficient High-Dimensional Quantum Key Distribution

June 12, 2014
Author(s)
Tian Zhong, Hongchao Zhou, Ligong Wang, Gregory Wornell, Zheshen Zhang, Jeffrey Shapiro, Franco N. Wong, Rob Horansky, Varun Verma, Adriana Lita, Richard Mirin, Thomas Gerrits, Sae Woo Nam, Alessandro Restelli, Joshua Bienfang, Francesco Marsili, Matthew Shaw
We demonstrate two high-dimensional QKD protocols - secure against collective Gaussian attacks - yielding up to 8.6 secure bits per photon and 6.7 Mb/s throughput, with 6.9 bits per photon after transmission through 20 km of fiber.

Polar codes in a QKD Environment

May 22, 2014
Author(s)
Anastase Nakassis, Alan Mink
Polar coding is the most recent encoding scheme in the quest for error correction codes that approaches the Shannon limit, has a simple structure, and admits fast decoders. As such, it is an interesting candidate for the quantum key distribution (QKD)

A single photon transistor based on superconducting systems

May 12, 2014
Author(s)
Marco Manzoni, Florentin Reiter, Jacob Taylor, Anders Sorensen
In analogy with electronic transistors, a single photon transistor is a device where the presence or absence of a single gate photon controls the propagation of a large number of signal photons [1, 2]. Such devices would represent a milestone in our

Topological physics with light

May 1, 2014
Author(s)
Jacob M. Taylor, Mohammad Hafezi
Electrons in a so-called topological insulator circulate around the material’s boundary without ever straying into the bulk. Uncharged photons can be induced to carry out similar behavior.

Direct generation of three-photon polarization entanglement

April 28, 2014
Author(s)
Deny Hamel, Krister Shalm, Hannes Hubel, Aaron J. Miller, Francesco F. Marsili, Varun Verma, Richard Mirin, Sae Woo Nam, Kevin Resch, Thomas Jennewein
Non-classical states of light are of fundamental importance for emerging quantum technologies. All optics experiments producing multi-qubit entangled states have until now relied on outcome post-selection, a procedure where only the measurement results
