Two studies show breakthroughs that could boost quantum technology

Scientists with the Pritzker School of Molecular Engineering at the University of Chicago have made two breakthroughs in the quest to develop quantum technology. In one study, they entangled two quantum bits using sound for the first time; in another, they built the highest-quality long-range link between two qubits to date. The work brings us closer to harnessing quantum technology to make more powerful computers, ultra-sensitive sensors and secure transmissions.

“Both of these are transformative steps forward to quantum communications,” said co-author Andrew Cleland, the John A. MacLean Sr. Professor of Molecular Engineering at the PME and UChicago-affiliated Argonne National Laboratory. A leader in the development of superconducting quantum technology, he led the team that built the first “quantum machine,” demonstrating quantum performance in a mechanical resonator. “One of these experiments shows the precision and accuracy we can now achieve, and the other demonstrates a fundamental new ability for these qubits.”
