Nash equilibria in quantum games with generalized two-parameter strategies
Adrian P. Flitney, Lloyd C. L. Hollenberg
In the Eisert protocol for 2 X 2 quantum games [Phys. Rev. Lett. 83, 3077], a number of authors have investigated the features arising from making the strategic space a two-paramet…
Quantum phase transitions of light
Andrew D. Greentree, Charles Tahan, Jared H. Cole +1
Recently, condensed matter and atomic experiments have reached a length-scale and temperature regime where new quantum collective phenomena emerge. Finding such physics in systems…
A multiplexed single electron transistor for application in scalable solid-state quantum computing
Vincent I. Conrad, Andrew D. Greentree, Lloyd C. L. Hollenberg
Single Electron Transistors (SETs) are nanoscale electrometers of unprecedented sensitivity, and as such have been proposed as read-out devices in a number of quantum computer arch…
Gate-level simulation of logical state preparation
A. M. Stephens, S. J. Devitt, A. G. Fowler +2
Quantum error correction and fault-tolerant quantum computation are two fundamental concepts which make quantum computing feasible. While providing a theoretical means with which t…
Stark shift control of single optical centers in diamond
Ph. Tamarat, T. Gaebel, J. R. Rabeau +8
Lifetime limited optical excitation lines of single nitrogen vacancy (NV) defect centers in diamond have been observed at liquid helium temperature. They display unprecedented spec…
Scalable Error Correction in Distributed Ion Trap Computers
Daniel K. L. Oi, Simon J. Devitt, Lloyd C. L. Hollenberg
A major challenge for quantum computation in ion trap systems is scalable integration of error correction and fault tolerance. We analyze a distributed architecture with rapid high…
Cross-talk compensation of hyperfine control in donor qubit architectures
G Kandasamy, C J Wellard, L C L Hollenberg
We theoretically investigate cross-talk in hyperfine gate control of donor-qubit quantum computer architectures, in particular the Kane proposal. By numerically solving the Poisson…
