1. A system, the system comprising:
a signal generator configured to generate an in-phase (I) signal and a quadrature-phase (Q) signal, wherein the I signal and the Q signal are at an intermediate frequency (IF);
a first mixer configured to mix the I signal and the Q signal with a local oscillator (LO) signal to produce a radio frequency (RF) signal, wherein the RF signal is sent to a quantum element;
a second mixer configured to mix a portion of the RF signal with a tone offset from the LO signal to produce a baseband signal; and
a signal analyzer configured to determine an adjustment to one or both of the I signal and the Q signal according to the baseband signal, wherein:
the adjustment modifies the RF signal sent to the quantum element,
the system comprises a quantum refrigerator configured to receive the RF signal and operable to generate a refrigerator response, and
the second mixer is operable to switch between downconverting the portion of the RF signal and downconverting the quantum refrigerator response.
