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…
Bounds on the Probability of Success of Postselected Non-linear Sign Shifts Implemented with Linear Optics
E. Knill
The fundamental gates of linear optics quantum computation are realized by using single photons sources, linear optics and photon counters. Success of these gates is conditioned on…
A subsystem-independent generalization of entanglement
Howard Barnum, Emanuel Knill, Gerardo Ortiz +2
We introduce a generalization of entanglement based on the idea that entanglement is relative to a distinguished subspace of observables rather than a distinguished subsystem decom…
Quantum Simulations of Physics Problems
Rolando Somma, Gerardo Ortiz, Emanuel Knill +1
If a large Quantum Computer (QC) existed today, what type of physical problems could we efficiently simulate on it that we could not simulate on a classical Turing machine? In this…
A note on verification procedures for quantum noiseless subsystems
Lorenza Viola, Emanuel Knill
We establish conditions under which the experimental verification of quantum error-correcting behavior against a linear set of error operators $\ce$ suffices for the verification o…
