Consider an array of qubits forming a register. Now, a cavity resonator’s state can be expanded in a photon number basis. If you truncate the cavity resonator to 2^n photons, then map the 0 photon ket to the 0 state of the register, the 1 photon key to the 1 state of the register, all the way up to the 2^n photon state of the register to the 2^n photon state of the register. Now you’ve mapped the cavity state onto the register and they’re informationally equivalent
- adamnemecek 9y agosure, however analog computing has the advantage that you can solve optimization problems natively, in hardware. with qubits, you get a speedup but not O(1) solutions.
- gaze 9y agoAbsolutely not. The time complexity is exactly the same. A quantum computer can simulate quantum annealing with exactly the same asymptotic complexity as an “analog” physical system that takes advantage of quantum mechanics would.
- adamnemecek 9y agoI disagree but ok.
