Quantum computation with femtosecond photon echo

Not Accessible

Your library or personal account may give you access

Abstract

We propose three-pulse four-wave mixing in cooled molecules for quantum computation. Femtosecond amplitude and phase shaped pulses encode information into a coherent superposition of vibrational states. The coherent coupling between the quantum states and the consecutive interactions with shaped pulses is used as quantum logic gates to create the final superposition of states. The resulting coherent virtual or stimulated photon echo signal corresponds to a vector or a matrix output, respectively. The concept, experimental setup, and preliminary results are presented.
