To cool quantum computing components, researchers use machines called dilution refrigerators. Researchers and engineers from the SQMS Center are building Colossus, the largest, most powerful refrigerator at millikelvin temperatures ever made. The new machine will enable new physics and quantum computing experiments.
From the New York Times, Nov. 30, 2022: Yesterday, a science team led by Cal Tech announced they had simulated a pair of black holes in a quantum computer and sent a message between them through a shortcut in space-time called a wormhole. Fermilab’s Joe Lykken co-authored the paper published in Nature yesterday and provides details on what the team uncovered.
From Quantum Computing Report, April 30, 2022: A Fermilab quantum engineering team has collaborated with the University of Chicago to create a new open-source design for control electronics for superconducting quantum processors called the Quantum Instrumentation Control Kit.
Scientists at the Fermilab-led SQMS Center investigate qubits at the atomic level to identify sources of various impurities. By having a deeper understanding of how impurities affect how long a qubit can store information, scientists will be able to figure out how to further improve the performance of quantum computers.
