Local Fault-tolerant Quantum Computation
Krysta M. Svore, Barbara M. Terhal, David P. DiVincenzo
We analyze and study the effects of locality on the fault-tolerance threshold for quantum computation. We analytically estimate how the threshold will depend on a scale parameter r…
Security Trade-offs in Ancilla-Free Quantum Bit Commitment in the Presence of Superselection Rules
D. P. DiVincenzo, J. A. Smolin, B. M. Terhal
Security trade-offs have been established for one-way bit commitment in quant-ph/0106019. We study this trade-off in two superselection settings. We show that for an `abelian' supe…
Fermionic Linear Optics Revisited
David. P. DiVincenzo, Barbara M. Terhal
We provide an alternative view of the efficient classical simulatibility of fermionic linear optics in terms of Slater determinants. We investigate the generic effects of two-mode…
Fault-Tolerant Quantum Computation For Local Non-Markovian Noise
Barbara M. Terhal, Guido Burkard
We derive a threshold result for fault-tolerant quantum computation for local non-Markovian noise models. The role of error amplitude in our analysis is played by the product of th…
Electron spin detection in the frequency domain under the interrupted Oscillating Cantilever-driven Adiabatic Reversal (iOSCAR) Protocol
M. Ting, A. O. Hero, D. Rugar +2
Magnetic Resonance Force Microscopy (MRFM) is an emergent technology for measuring spin-induced attonewton forces using a micromachined cantilever. In the interrupted Oscillating C…
