This is the scaffolding for measuring and manipulating quantum states. Quantum computing itself is not "analog" in the original, signal processing meaning of the word: the states are not isomorphic analogies for modelled physical processes.
- klyrs 7y agoIt's true that qubit states are inherently quantized. However, the control circuitry, couplers or gates, and often the qubits themselves, are analog devices. The "un-sexy" truth is that calibration is one of the most difficult parts of producing a useful quantum computer.
- varjag 7y agoSure, and any PC has tons of analog circuits too, for example speaker output. The calibration and scaffolding in quantum computers isn't a model of anything. Not in the same way as opamp board in this article is an analogy of integral.
