Power law scaling for the adiabatic algorithm for search engine ranking
Adam Frees, John King Gamble, Kenneth Rudinger +4
An important method for search engine result ranking works by finding the principal eigenvector of the "Google matrix." Recently, a quantum algorithm for preparing this eigenvector…
Coherent Quantum Oscillations in a Silicon Charge Qubit
Zhan Shi, C. B. Simmons, Daniel. R. Ward +10
Fast quantum oscillations of a charge qubit in a double quantum dot fabricated in a Si/SiGe heterostructure are demonstrated and characterized experimentally. The measured inhomoge…
Pulse-gated quantum dot hybrid qubit
Teck Seng Koh, John King Gamble, Mark Friesen +2
A quantum dot hybrid qubit formed from three electrons in a double quantum dot has the potential for great speed, due to presence of level crossings where the qubit becomes charge-…
Comparing algorithms for graph isomorphism using discrete- and continuous-time quantum random walks
Kenneth Rudinger, John King Gamble, Eric Bach +3
Berry and Wang [Phys. Rev. A {\bf 83}, 042317 (2011)] show numerically that a discrete-time quantum random walk of two noninteracting particles is able to distinguish some non-isom…
Non-interacting multi-particle quantum random walks applied to the graph isomorphism problem for strongly regular graphs
Kenneth Rudinger, John King Gamble, Mark Wellons +4
We investigate the quantum dynamics of particles on graphs ("quantum random walks"), with the aim of developing quantum algorithms for determining if two graphs are isomorphic (rel…
Two-electron dephasing in single Si and GaAs quantum dots
John King Gamble, Mark Friesen, S. N. Coppersmith +1
We study the dephasing of two-electron states in a single quantum dot in both GaAs and Si. We investigate dephasing induced by electron-phonon coupling and by charge noise analytic…
