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…
Fast Quantum Modular Exponentiation
R. Van Meter, K. M. Itoh
We present a detailed analysis of the impact on modular exponentiation of architectural features and possible concurrent gate execution. Various arithmetic algorithms are evaluated…
Electron spin phase relaxation of phosphorus donors in nuclear spin enriched silicon
Eisuke Abe, Kohei M. Itoh, Junichi Isoya +1
We report a pulsed EPR study of the phase relaxation of electron spins bound to phosphorus donors in isotopically purified 29^Si and natural abundance Si single crystals measured a…
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…
Critical exponents for the metal-insulator transition of ^{70}Ge:Ga in magnetic fields
Michio Watanabe, Kohei M. Itoh, Masashi Morishita +2
We have measured the electrical conductivity of nominally uncompensated ^{70}Ge:Ga samples in magnetic fields up to B=8 T at low temperatures (T=0.05-0.5 K) in order to investigate…
An all silicon quantum computer
T. D. Ladd, J. R. Goldman, F. Yamaguchi +3
A solid-state implementation of a quantum computer composed entirely of silicon is proposed. Qubits are Si-29 nuclear spins arranged as chains in a Si-28 (spin-0) matrix with Larmo…
