Quantum theory of optical feedback via homodyne detection.
  • Wiseman, Milburn
  • Physics, Medicine
  • Physical review letters
  • 1 February 1993
We present a quantum theory of feedback in which the homodyne photocurrent alters the dynamics of the source cavity. To the nonlinear stochastic (Ito) evolution of the conditioned system state we addExpand

  • Physical review. A, Atomic, molecular, and…
  • 1993
The quantum effects on a cavity mode of the electromagnetic field caused by measuring one of its quadrature components is analyzed. We consider three measurement schemes: an intracavityExpand

Quantum optical Fredkin gate.
  • Milburn
  • Physics, Medicine
  • Physical review letters
  • 1 May 1989
A simple optical model to realize a reversible, potentially error-free logic gate a Fredkin gate is discussed. The device dissipates no energy and makes use of the Kerr nonlinearity to produceExpand

Quantum-mechanical model for continuous position measurements.
  • Caves, Milburn
  • Physics, Medicine
  • Physical review. A, General physics
  • 15 December 1987
We present an idealized model for a sequence of position measurements, and we then take an appropriate limit in which the measurements become continuous. The measurements lead to fluctuations withoutExpand

Effect of dissipation on quantum coherence.
  • Walls, Milburn
  • Medicine, Physics
  • Physical review. A, General physics
  • 1985
The effect of dissipation on a macroscopic superposition of quantum states is studied with use of a Markovian master-equation approach. It is shown that a superposition of two states is reduced to aExpand

Quantum and classical Liouville dynamics of the anharmonic oscillator.
  • Milburn
  • Medicine, Physics
  • Physical review. A, General physics
  • 1986
We consider the dynamics of a quantum joint phase-space probability density in an exactly solvable model. The density is defined to be a true (i.e., positive) probability distribution for approximateExpand

Squeezing via feedback.
  • Wiseman, Milburn
  • Medicine, Physics
  • Physical review. A, Atomic, molecular, and…
  • 1 February 1994
We present the quantum theory of optical cavity feedback mediated by homodyne detection, with an arbitrary time delay. We apply this theory to a system with nonclassical dynamics, a sub-PoissonianExpand

All-optical versus electro-optical quantum-limited feedback.
  • Wiseman, Milburn
  • Physics, Medicine
  • Physical review. A, Atomic, molecular, and…
  • 1 May 1994
All-optical feedback can be effected by putting the output of a source cavity through a Faraday isolator and into a second cavity which is coupled to the source cavity by a nonlinear crystal. If theExpand

Universal teleportation with a twist
We give a transfer theorem for teleportation based on twisting the entanglement measurement. This allows one to say what local unitary operation must be performed to complete the teleportation in anyExpand

  • 1 March 1993
It is shown that the evolution of an open quantum system whose density operator obeys a Markovian master equation can in some cases be meaningfully described in terms of stochastic SchrodingerExpand
