Abstract

Optical systems are promising candidates for the implementation of quantum computation protocols involving many qubits, or many qu-modes in the continuous variable case. Recent technological progresses have allowed to create and individually squeeze several modes of the electromagnetic field (either spatial or temporal) in a cavity [1]. These squeezed modes can be mixed by linear optic networks to produce cluster states [1], a resource for measurement-based quantum computation [2]. The complexity of the network to use for this goal grows rapidly with the number of modes, rendering this method poorly scalable.
