Aren’t the 0 and 1 states of a qubit basically the zero mode (ground state) and first mode of the quantum system? So, there can be superposition of the modes, but when measured (with an EM pulse), it either re-emits the pulse (producing a 1) or absorbs it (producing a 0). Is that correct? I recently learned there are qubits that have more than 2 modes… like a qutrit, with 3: https://en.wikipedia.org/wiki/Qutrit https://en.wikipedia.org/wiki/Qutrit
