1. An amplification circuit, comprising:
a superconducting component;
an amplifier coupled in parallel with the superconducting component;
a voltage source coupled to a first input of the amplifier;
one or more resistors coupled to a second input of the amplifier; and
an output terminal coupled to an output of the amplifier, a voltage at the output terminal being proportional to a ratio of a resistance of the superconducting component to another resistance of the one or more resistors that are coupled to the second input of the superconducting component.
