Elementary gates for quantum computation.

- Barenco, Bennett, +6 authors Weinfurter
- Physics, Medicine
- Physical review. A, Atomic, molecular, and…
- 23 March 1995

We show that a set of gates that consists of all one-bit quantum gates (U(2)) and the two-bit exclusive-or gate (that maps Boolean values (x,y) to (x,x ⊕y)) is universal in the sense that all unitary… Expand

Teleporting an unknown quantum state via dual classical and Einstein-Podolsky-Rosen channels.

- Bennett, Brassard, Crépeau, Józsa, Pérès, Wootters
- Physics, Medicine
- Physical review letters
- 29 March 1993

An unknown quantum state \ensuremath{\Vert}\ensuremath{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen… Expand

Mixed-state entanglement and quantum error correction.

- Bennett, DiVincenzo, Smolin, Wootters
- Physics, Medicine
- Physical review. A, Atomic, molecular, and…
- 23 April 1996

Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs) provide two ways of protecting quantum states from interaction with the environment. In an EPP, perfectly… Expand

Communication via one- and two-particle operators on Einstein-Podolsky-Rosen states.

As is well known, operations on one particle of an Einstein-Podolsky-Rosen (EPR) pair cannot influence the marginal statistics of measurements on the other particle. We characterize the set of states… Expand

Purification of noisy entanglement and faithful teleportation via noisy channels.

- Bennett, Brassard, Popescu, Schumacher, Smolin, Wootters
- Physics, Medicine
- Physical review letters
- 20 November 1995

Two separated observers, by applying local operations to a supply of not-too-impure entangled states ({\em e.g.} singlets shared through a noisy channel), can prepare a smaller number of entangled… Expand

Quantum cryptography without Bell's theorem.

Ekert has described a cryptographic scheme in which Einstein-Podolsky-Rosen (EPR) pairs of particles are used to generate identical random numbers in remote places, while Bell’s theorem certifies… Expand

Concentrating partial entanglement by local operations.

- Bennett, Bernstein, Popescu, Schumacher
- Physics, Medicine
- Physical review. A, Atomic, molecular, and…
- 21 November 1995

If two separated observers are supplied with entanglement, in the form of n pairs of particles in identical partly entangled pure states, one member of each pair being given to each observer, they… Expand

Parity bit in quantum cryptography.

An $n$-bit string is encoded as a sequence of non-orthogonal quantum states. The parity bit of that $n$-bit string is described by one of two density matrices, $\rho_0^{(n)}$ and $\rho_1^{(n)}$, both… Expand

On a coin tossing problem by G .

Tverberg, H., On a coin tossing problem by G. Bennett, Discrete Mathematics 115 (1993) 293-294. For a certain class of games, Bennett proved that player B never has a smaller chance of winning than… Expand
