A Femtosecond Nanometer Free Electron Source
Peter Hommelhoff, Yvan Sortais, Anoush Aghajani-Talesh +1
We report a source of free electron pulses based on a field emission tip irradiated by a low-power femtosecond laser. The electron pulses are shorter than 70 fs and originate from…
Architecture-Dependent Execution Time of Shor's Algorithm
Rodney Van Meter, Kohei M. Itoh, Thaddeus D. Ladd
We show how the execution time of algorithms on quantum computers depends on the architecture of the quantum computer, the choice of algorithms (including subroutines such as arith…
Coherence Time of a Solid-State Nuclear Qubit
T. D. Ladd, D. Maryenko, E. Abe +2
We report NMR experiments using high-power, RF decoupling techniques to show that a 29-Si nuclear spin qubit in a solid silicon crystal at room temperature can preserve quantum pha…
Generation of photon number states
Edo Waks, Eleni Diamanti, Yoshihisa Yamamoto
The Visible Light Photon Counter (VLPC) has the capability to discriminate photon number states, in contrast to conventional photon counters which can only detect the presence or a…
Direct observation of non-classical photon statistics in parametric downconversion
Edo Waks, Eleni Diamanti, Barry C. Sanders +2
We employ a high quantum efficiency photon number counter to determine the photon number distribution of the output field from a parametric downconverter. The raw photocount data d…
Optical Detection of a Single Nuclear Spin
K-M. C. Fu, T. D. Ladd, C. Santori +1
We propose a method to optically detect the spin state of a 31-P nucleus embedded in a 28-Si matrix. The nuclear-electron hyperfine splitting of the 31-P neutral-donor ground state…
