Description
Continuous Variables are a promising platform for demonstrating large scale quantum information effects thanks to the experimental advantages they provide. In this framework, we define a general quantum computational model based on a continuous variables hardware. It consists in vacuum input states, a finite set of gates — including non-Gaussian elements — and homodyne detection. We show that this model enables the encoding of fault tolerant universal quantum computing. Furthermore, when restricted to only commuting gates it turns into a sampling problem that can’t be simulated efficiently with a classical computer — unless the polynomial hierarchy collapses. Thus we provide a simple paradigm for short-term experiments relying on Gaussian states, homodyne detection and some form of non-Gaussian evolution.
