Quantum algorithm for linear systems of equations.

- A. Harrow, Avinatan Hassidim, S. Lloyd
- Medicine, Mathematics
- Physical review letters
- 19 November 2008

Solving linear systems of equations is a common problem that arises both on its own and as a subroutine in more complex problems: given a matrix A and a vector b(-->), find a vector x(-->) such that… Expand

Ultimate physical limits to computation

- S. Lloyd
- Physics, Medicine
- Nature
- 13 August 1999

Computers are physical systems: the laws of physics dictate what they can and cannot do. In particular, the speed with which a physical device can process information is limited by its energy and the… Expand

Advances in quantum metrology

- V. Giovannetti, S. Lloyd, L. Maccone
- Physics, Mathematics
- 11 February 2011

The statistical error in any estimation can be reduced by repeating the measurement and averaging the results. The central limit theorem implies that the reduction is proportional to the square root… Expand

Quantum-Enhanced Measurements: Beating the Standard Quantum Limit

- V. Giovannetti, S. Lloyd, L. Maccone
- Physics, Medicine
- Science
- 19 November 2004

Quantum mechanics, through the Heisenberg uncertainty principle, imposes limits on the precision of measurement. Conventional measurement techniques typically fail to reach these limits. Conventional… Expand

Computational capacity of the universe.

- S. Lloyd
- Physics, Medicine
- Physical review letters
- 24 October 2001

All physical systems register and process information. The laws of physics determine the amount of information that a physical system can register (number of bits) and the number of elementary logic… Expand
