Quantum theory, the Church–Turing principle and the universal quantum computer

- D. Deutsch
- Mathematics
- Proceedings of the Royal Society of London. A…
- 8 July 1985

It is argued that underlying the Church–Turing hypothesis there is an implicit physical assertion. Here, this assertion is presented explicitly as a physical principle: ‘every finitely realizible… Expand

Rapid solution of problems by quantum computation

- D. Deutsch, R. Jozsa
- Mathematics
- Proceedings of the Royal Society of London…
- 1 October 1992

A class of problems is described which can be solved more efficiently by quantum computation than by any classical or stochastic method. The quantum computation solves the problem with certainty in… Expand

Quantum computational networks

- D. Deutsch
- Mathematics
- Proceedings of the Royal Society of London. A…
- 8 September 1989

The theory of quantum computational networks is the quantum generalization of the theory of logic circuits used in classical computing machines. Quantum gates are the generalization of classical… Expand

Quantum theory of probability and decisions

- D. Deutsch
- Mathematics, Physics
- Proceedings of the Royal Society of London…
- 4 June 1999

The probabilistic predictions of quantum theory are conventionally obtained from a special probabilistic axiom. But that is unnecessary because all the practical consequences of such predictions… Expand

Uncertainty in Quantum Measurements

- D. Deutsch
- Mathematics
- 28 February 1983

The object of this Letter is to show that except in the case of canonically conjugate observables, the generalized Heisenberg inequality does not properly express the quantum uncertainty principle.… Expand

Quantum theory as a universal physical theory

- D. Deutsch
- Mathematics
- 1985

The problem of setting up quantum theory as a universal physical theory is investigated. It is shown that the existing formalism, in either the conventional or the Everett interpretation, must be… Expand

The fabric of reality : the science of parallel universes-- and its implications

- D. Deutsch
- Computer Science
- 1997

TLDR

Information flow in entangled quantum systems

- D. Deutsch, P. Hayden
- Physics
- Proceedings of the Royal Society of London…
- 1 June 1999

All information in quantum systems is, notwithstanding Bell's theorem, localized. Measuring or otherwise interacting with a quantum system S has no effect on distant systems from which S is… Expand

Machines, logic and quantum physics

- D. Deutsch, A. Ekert, Rossella Lupacchini
- Computer Science, Mathematics
- Bull. Symb. Log.
- 19 November 1999

TLDR

Universality in quantum computation

- D. Deutsch, A. Barenco, A. Ekert
- Computer Science, Mathematics
- Proceedings of the Royal Society of London…
- 24 May 1995

We show that in quantum computation almost every gate that operates on two or more bits is a universal gate. We discuss various physical considerations bearing on the proper definition of… Expand
