A scheme for efficient quantum computation with linear optics
TLDR
It is shown that efficient quantum computation is possible using only beam splitters, phase shifters, single photon sources and photo-detectors and are robust against errors from photon loss and detector inefficiency. Expand
Theory of quantum error-correcting codes
Quantum error correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory ofExpand
Nonbinary quantum stabilizer codes
TLDR
This work defines and shows how to construct nonbinary quantum stabilizer codes, a relationship between self-orthogonal codes over F(q/sup 2/) and q-ary quantum codes for any prime power q, based on nonbinary error bases. Expand

TLDR
This work reports a simple architecture for fault-tolerant quantum computing, providing evidence that accurate quantum computing is possible for EPGs as high as three per cent, and shows that non-trivial quantum computations at EPG’s of as low as one per cent could be implemented. Expand
A Theory of Quantum Error-Correcting Codes
Quantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory ofExpand
Power of One Bit of Quantum Information
In standard quantum computation, the initial state is pure and the answer is determined by making a measurement of some of the bits in the computational basis. What can be accomplished if the initialExpand
Reversing quantum dynamics with near-optimal quantum and classical fidelity
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 approximateExpand
Restrictions on transversal encoded quantum gate sets.
TLDR
It is shown that the ability of a quantum code to detect an arbitrary error on any single physical subsystem is incompatible with the existence of a universal, transversal encoded gate set for the code. Expand
A strong loophole-free test of local realism
TLDR
An loophole-free test of Bells inequalities and the probability that local realism is compatible with the results is less than 5.9×10<sup>-9</sup>. Expand
Randomized Benchmarking of Quantum Gates
A key requirement for scalable quantum computing is that elementary quantum gates can be implemented with sufficiently low error. One method for determining the error behavior of a gateExpand
