Fault-Tolerant Postselected Quantum Computation: Threshold Analysis
E. Knill
The schemes for fault-tolerant postselected quantum computation given in [Knill, Fault-Tolerant Postselected Quantum Computation: Schemes, http://arxiv.org/abs/quant-ph/0402171] ar…
Entanglement beyond subsystems
Lorenza Viola, Howard Barnum, Emanuel Knill +2
We present a notion of generalized entanglement which goes beyond the conventional definition based on quantum subsystems. This is accomplished by directly defining entanglement as…
Entanglement as an Observer-Dependent Concept: An Application to Quantum Phase Transitions
Gerardo Ortiz, Rolando Somma, Howard Barnum +2
This paper addresses the following main question: Do we have a theoretical understanding of entanglement applicable to a full variety of physical settings? It is clear that not onl…
Fault-Tolerant Postselected Quantum Computation: Schemes
E. Knill
Postselected quantum computation is distinguished from regular quantum computation by accepting the output only if measurement outcomes satisfy predetermined conditions. The output…
Scalable Quantum Computation in the Presence of Large Detected-Error Rates
E. Knill
The tolerable erasure error rate for scalable quantum computation is shown to be at least 0.292, given standard scalability assumptions. This bound is obtained by implementing comp…
Introduction to NMR Quantum Information Processing
R. Laflamme, E. Knill, D. G. Cory +11
After a general introduction to nuclear magnetic resonance (NMR), we give the basics of implementing quantum algorithms. We describe how qubits are realized and controlled with RF…
