Quantum Metrology Enhanced by Repetitive Quantum Error Correction.
Thomas Unden, P. Balasubramanian, Daniel Louzon +12 more·Feb 23, 2016
We experimentally demonstrate the protection of a room-temperature hybrid spin register against environmental decoherence by performing repeated quantum error correction whilst maintaining sensitivity to signal fields. We use a long-lived nuclear spi...
Noise-Resilient Quantum Computing with a Nitrogen-Vacancy Center and Nuclear Spins.
J. Casanova, Zhen-Yu Wang, M. Plenio·Feb 22, 2016
Selective control of qubits in a quantum register for the purposes of quantum information processing represents a critical challenge for dense spin ensembles in solid-state systems. Here we present a protocol that achieves a complete set of selective...
Noise filtering of composite pulses for singlet-triplet qubits
Xu-Chen Yang, Xin Wang·Feb 18, 2016
Semiconductor quantum dot spin qubits are promising candidates for quantum computing. In these systems, the dynamically corrected gates offer considerable reduction of gate errors and are therefore of great interest both theoretically and experimenta...
The role of master clock stability in scalable quantum information processing
H. Ball, W. Oliver, M. Biercuk·Feb 15, 2016
Experimentalists seeking to improve the coherent lifetimes of quantum bits have generally focused on mitigating decoherence mechanisms through, for example, improvements to qubit designs and materials, and system isolation from environmental perturba...
Error Sensitivity to Environmental Noise in Quantum Circuits for Chemical State Preparation.
Nicolas P. D. Sawaya, M. Smelyanskiy, J. McClean +1 more·Feb 4, 2016
Calculating molecular energies is likely to be one of the first useful applications to achieve quantum supremacy, performing faster on a quantum than a classical computer. However, if future quantum devices are to produce accurate calculations, error...
New class of quantum error-correcting codes for a bosonic mode
M. Michael, M. Silveri, R. T. Brierley +4 more·Jan 29, 2016
We construct a new class of quantum error-correcting codes for a bosonic mode which are advantageous for applications in quantum memories, communication, and scalable computation. These 'binomial quantum codes' are formed from a finite superposition ...
Notch filtering the nuclear environment of a spin qubit.
F. Malinowski, F. Martins, Peter D. Nissen +8 more·Jan 25, 2016
Electron spins in gate-defined quantum dots provide a promising platform for quantum computation. In particular, spin-based quantum computing in gallium arsenide takes advantage of the high quality of semiconducting materials, reliability in fabricat...
Superdense Coding Interleaved with Forward Error Correction
Ronald J. Sadlier, T. Humble·Jan 23, 2016
Abstract Superdense coding promises increased classical capacity and communication security but this advantage may be undermined by noise in the quantum channel. We present a numerical study of how forward error correction (FEC) applied to the encode...
The Origin of the Dynamical Quantum Non-locality
Cesar E. Pachon, Leonardo A. Pachon·Jul 16, 2013
Non-locality is one of the hallmarks of quantum mechanics and is responsible for paradigmatic features such as entanglement and the Aharonov-Bohm effect. Non-locality comes in two flavours: a \emph{kinematic} non-locality -- arising from the structur...
Reversing quantum dynamics with near-optimal quantum and classical fidelity
H. Barnum, E. Knill·Apr 23, 2000
We consider the problem of reversing quantum dynamics, with the goal of preserving an initial state's quantum entanglement or classical correlation with a reference system. We exhibit an approximate reversal operation, adapted to the initial density ...
