Abstract
Technologies for impedance matching networks for qubits are disclosed. In one illustrative embodiment, an impedance matching network matches a 50 Ohm transmission line to a spin qubit with a state-dependent resistance of 100 kiloohms to 105 kiloohms. The illustrative impedance matching network is tunable, allowing the impedance transformation ratio to be changed without significantly changing the matching frequency of the impedance matching network. In some embodiments, the impedance matching network matches a 50 Ohm transmission line to a lower-resistance state of a qubit. In other embodiments, the impedance matching network matches a 50 Ohm transmission line to an impedance value in between a lower-resistance state and a higher-resistance state of a qubit.
