Merged-Element Transmons: Design and Qubit Performance
H. J. Mamin, E. Huang, S. Carnevale +12
We have demonstrated a novel type of superconducting transmon qubit in which a Josephson junction has been engineered to act as its own parallel shunt capacitor. This merged-elemen…
Decoherence of near-surface nitrogen-vacancy centers due to electric field noise
M. Kim, H. J. Mamin, M. H. Sherwood +3
We show that electric field noise from surface charge fluctuations can be a significant source of spin decoherence for near-surface nitrogen-vacancy (NV) centers in diamond. This c…
Proton magnetic resonance imaging with a nitrogen-vacancy spin sensor
D. Rugar, H. J. Mamin, M. H. Sherwood +4
Nuclear magnetic resonance (NMR) imaging with nanometer resolution requires new detection techniques with sensitivity well beyond the capability of conventional inductive detection…
Multipulse Double-Quantum Magnetometry With Near-Surface Nitrogen Vacancy Centers
H. J. Mamin, M. H. Sherwood, M. Kim +4
We discuss multipulse magnetometry that exploits all three magnetic sublevels of the S=1 nitrogen-vacancy center in diamond to achieve enhanced magnetic field sensitivity. Based on…
Detecting External Electron Spins Using Nitrogen-Vacancy Centers
H. J. Mamin, M. H. Sherwood, D. Rugar
Near-surface nitrogen-vacancy (NV) centers have been created in diamond through low energy implantation of 15N to sense electron spins that are external to the diamond. By performi…
Force-detected nuclear double resonance between statistical spin polarizations
M. Poggio, H. J. Mamin, C. L. Degen +2
We demonstrate nuclear double resonance for nanometer-scale volumes of spins where random fluctuations rather than Boltzmann polarization dominate. When the Hartmann-Hahn condition…
Experimental realization of Shor's quantum factoring algorithm using nuclear magnetic resonance
Lieven M. K. Vandersypen, Matthias Steffen, Gregory Breyta +3
The number of steps any classical computer requires in order to find the prime factors of an -digit integer increases exponentially with , at least using algorithms known…
Non-thermal nuclear magnetic resonance quantum computing using hyperpolarized Xenon
Anne S. Verhulst, Oskar Liivak, Mark H. Sherwood +2
Current experiments in liquid-state nuclear magnetic resonance quantum computing are limited by low initial polarization. To address this problem, we have investigated the use of o…
Implementation of a three-quantum-bit search algorithm
Lieven M. K. Vandersypen, Matthias Steffen, Mark H. Sherwood +3
We report the experimental implementation of Grover's quantum search algorithm on a quantum computer with three quantum bits. The computer consists of molecules of C-labeled…
Nuclear Magnetic Resonance Quantum Computing Using Liquid Crystal Solvents
Costantino S. Yannoni, Mark H. Sherwood, Lieven M. K. Vandersypen +3
Liquid crystals offer several advantages as solvents for molecules used for nuclear magnetic resonance quantum computing (NMRQC). The dipolar coupling between nuclear spins manifes…
Realization of logically labeled effective pure states for bulk quantum computation
Lieven M. K. Vandersypen, Costantino S. Yannoni, Mark H. Sherwood +1
We report the first use of "logical labeling" to perform a quantum computation with a room-temperature bulk system. This method entails the selection of a subsystem which behaves a…
Experimental Realization of A Two Bit Phase Damping Quantum Code
Debbie Leung, Lieven Vandersypen, Xinlan Zhou +4
Using nuclear magnetic resonance techniques, we experimentally investigated the effects of applying a two bit phase error detection code to preserve quantum information in nuclear…
