Necessary and sufficient conditions are given for the construction of a hybrid quantum computer that operates on both continuous and discrete quantum variables that are more efficient than conventional quantum computers for performing a variety of quantum algorithms.

Quantum computing with neutral atoms

- PhysicsNational science review
- 2019

A consequence of the cost of quantum error correction is that any viable approach to large-scale quantum computing needs to combine high-fidelity quantum logic operations with a capability for integrating large numbers of physical qubits.

Controlling photons in a box and exploring the quantum to classical boundary (Nobel Lecture).

Bicontinuous extensions of invertible combinatorial functions

- MathematicsMathematical systems theory
- 2005

The solution of the problem of constructing a diffeomorphic componentwise extension for an arbitrary invertible combinatorial function constitutes a proof of the physical realizability of general computing mechanisms based on reversible primitives.

The thermodynamics of computation—a review

- Physics
- 1982

Computers may be thought of as engines for transforming free energy into waste heat and mathematical work. Existing electronic computers dissipate energy vastly in excess of the mean thermal…

Logical reversibility of computation

- Computer Science
- 1973

This result makes plausible the existence of thermodynamically reversible computers which could perform useful computations at useful speed while dissipating considerably less than kT of energy per logical step.

ON A SIMPLE COMBINATORIAL STRUCTURE SUFFICIENT FOR SYBLYING NONTRIVIAL SELF-REPRODUCTION

- Computer Science
- 1976

It can be shown that even in a world governed by this system M nontrivial self-reproduction can be established, thus illuminating what simple combinatorial structures allow for the handling of such logical somewhat difficult phenomenas as self-organization, self- reproduction, etc.
