How to Steer a Quantum System over a Schrödinger Bridge

How to Steer a Quantum System over a Schrödinger Bridge A new approach to the steering problem for the Schrödinger equation relying on stochastic mechanics and on the theory of Schrödinger bridges is presented. Given the initial and final states ψ 0 and ψ 1, respectively, the desired quantum evolution is constructed with the aid of a reference quantum evolution. The Nelson process corresponding to the latter evolution is used as reference process in a Schrödinger bridge problem with marginal probability densities |ψ 0|2 and |ψ 1|2. This approach is illustrated by working out a simple Gaussian example. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals
