The Solovay-Kitaev algorithm
TL;DR: The algorithm can be used to compile Shor's algorithm into an efficient fault-tolerant form using only Hadamard, controlled-not, and π/8 gates, and is generalized to apply to multi-qubit gates and togates from SU(d).

TL;DR: This work has theoretically determined the conditions when AAPT is possible, and Surprisingly, entanglement is not required, and presents data obtained using both separable and entangled input states.

The Solovay-Kitaev algorithm
TL;DR: The proof of the Solovay-Kitaev theorem in the form of an efficient classical algorithm for compiling an arbitrary single-qubit gate into a sequence of gates from a fixed and finite set was presented in this paper.
Journal ArticleDOI
Programmable Quantum Gate Arrays
TL;DR: It is shown that a universal quantum gate array which can be programmed to perform any unitary operation exists only if one allows the gate array to operate in a probabilistic fashion, and that it is not possible to build a fixed, general purpose quantum computer which can been programmed to Perform an arbitrary quantum computation.
Journal ArticleDOI
Separable states are more disordered globally than locally.

TL;DR: A strong sense is given in which a separable state is more disordered globally than locally and a new necessary condition for separability of bipartite states in arbitrary dimensions is found.
