Terry Rudolph has an excellent paper arguing for continuous-variable quantum computers [1]. CV still uses entanglement. You can think of CV states as infinite dimensional qubits. So in a way it is still "digital". Something about quantum measurement is fundamentally digital. [1] https://arxiv.org/abs/1607.08535 https://arxiv.org/abs/1607.08535
