31. Real Time Data Acquisition Platform for Pulsed Measurements
Topic: Quantum Information
Published: Date unknown
Authors: Sergey V Polyakov, Alan L Migdall, Sae Woo Nam
Abstract: We present an inexpensive and simple data acquisition platform based on Field Programmable Gate Arrays (FPGAs) designed to acquire and characterize fast digital or analog electrical signal real time for processing on a generic personal computer. Whil ...

32. Realization of a programmable two-qubit quantum processor
Topic: Quantum Information
Published: 11/15/2009
Authors: David Hanneke, Jonathan Home, John D. Jost, Jason Amini, Dietrich G Leibfried, David J Wineland
Abstract: The universal quantum computer is a device that could simulate any physical system and represents a major goal for the field of quantum information science. Algorithms performed on such a device are predicted to offer significant gains for some impor ...

33. Reduced Deadtime and Higher Rate Photon-Counting Detection Using a Multiplexed Detector Array
Topic: Quantum Information
Published: 1/20/2007
Authors: Stefania Castelletto, Ivo Pietro Degiovanni, V Schettini, Alan L Migdall
Abstract: We present a scheme for a photon-counting detection system that can be operated at incident photon rates higher than otherwise possible by suppressing the effects of detector deadtime. The method uses an array of N detectors and a 1-by-N optical swit ...

34. Relativity and Optical Clocks
Topic: Quantum Information
Published: 9/24/2010
Authors: Chin W. Chou, David Hume, Till P Rosenband, David J Wineland
Abstract: Albert Einstein's theory of relativity forced us to alter our concepts of reality. One of the more startling outcomes of the theory is that we have to give up our notions of simultaneity. This is manifest in the so-called twin paradox in which a twin ...

35. Restrictions on Transversal Encoded Quantum Gate Sets
Topic: Quantum Information
Published: 3/18/2009
Authors: Bryan Keith Eastin, Emanuel H Knill
Abstract: Transversal gates play an important role in the theory of fault-tolerant quantum computation due to their simplicity and robustness to noise. By definition, transversal operators do not couple physical subsystems within the same code block. Consequen ...

36. Spectrally Bright and Broad Fiber-Based Heralded Single-Photon Source
Topic: Quantum Information
Published: 7/29/2008
Authors: Elizabeth Anne Goldschmidt, M D. Eisaman, Jingyun Fan, Sergey V Polyakov, Alan L Migdall
Abstract: We present the first experimental characterization of a heralded single-photon source based on spontaneous four-wave-mixing in a single-mode microstructure fiber. We measure the second-order correlation function, g(2)(0), to be far below the classi ...

37. State Discriminiation Signal Nulling Receivers
Topic: Quantum Information
Published: 9/6/2011
Authors: Francisco Elohim Becerra Chavez, Jingyun Fan, Gerald Baumgartner, Sergey V Polyakov, Julius Goldhar, Jonathan Kosloski, Alan L Migdall
Abstract: Optimized state-discrimination receiver strategies for nonorthogonal states can improve the capacity of the communication channels operating with error rates below the ones corresponding to conventional receivers. Coherent signal-nulling receivers us ...

38. The Cooper Pair Transistor
Topic: Quantum Information
Published: 9/17/2010
Author: Jose Alberto Aumentado
Abstract: The Cooper pair transistor (CPT) is a superconducting electrometer that has applications in quantum information as well as fundamental superconductivity studies. Since it operates in a near-dissipationless mode, it has potential as a minimally inva ...

39. Toward scalable ion traps for quantum information processing
Topic: Quantum Information
Published: 3/16/2010
Authors: Jason Amini, Hermann Uys, Janus H. Wesenberg, Signe Seidelin, Joseph Wright Britton, John J Bollinger, Dietrich G Leibfried, Christian Ospelkaus, Aaron Vandevender, David J Wineland
Abstract: The basic components for a quantum information processor using trapped ions have been demonstrated in a number of experiments. To perform complex algorithms that are not tractable with classical computers, these components need to be integrated and s ...

40. Ultra-cold mechanical resonators coupled to atoms in an optical lattice
Topic: Quantum Information
Published: 9/17/2009
Authors: Andrew Geraci, John E Kitching
Abstract: We propose an experiment utilizing an array of cooled micro-cantilevers coupled to a sample of ultra-cold atoms trapped near a micro-fabricated surface. The cantilevers allow individual lattice site addressing for atomic state control and readout, an ...
