Abstract
The technology described herein is directed towards real-time monitoring of qubit states in quantum computers using a system based on rf-SQUIDs (radio-frequency superconducting quantum interference devices) and a direct current signal that is sourced to a superconducting quantum circuit wire, and measured by, a classical computing device. In one implementation, the rf-SQUIDs are positioned at strategic locations, between superconducting quantum circuit wires, in a quantum computer, such as before and after attenuators, and before parametric amplifiers. The direct current control signal facilitates the detection of magnetic flux and inductance without adding load or noise to the superconducting quantum circuit wires, which enhances the detection of qubit state changes. The monitoring and detection system dynamically and precisely monitors qubit state changes and provides real-time feedback to the quantum processing unit to adjust the qubit states, and thereby maintain the integrity of quantum computations.
