From Qubits to Continuous-Variable Quantum Computation
arXiv:quant-ph/0208008
Abstract
By encoding a qudit in a harmonic oscillator and investigating the d --> infinity limit, we give an entirely new realization of continuous-variable quantum computation. The generalized Pauli group is generated by number and phase operators for harmonic oscillators.
