Impossibility to produce arbitrary non-Gaussian states using zero-mean Gaussian states and partial photon number resolving detection
Gaussian states and measurements collectively are not powerful-enough resources for quantum computing, as any Gaussian dynamics can be simulated efficiently, classically. However, it is known that any one non-Gaussian resource—a state, a unitary operation, or a measurement—together with Gaussian uni...
