A superconducting qubit is used to quantum control and measure quantum states of surface acoustic wave (SAW) phonons in a SAW resonator.
Significance and Impact
The work offers a straightforward approach to emit, detect, and manipulate quantum states of acoustic waves on the surface of solids.
- Method to integrate surface acoustic wave devices with superconducting qubits.
- Qubit used to probe surface acoustic wave device microwave response at millikelvin temperatures.
- Qubit can deterministically swap quantum excitation into SAW resonator and generate superposed quantum states.
- Qubit can measure Wigner tomogram of SAW quantum states.
Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation’s first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America’s scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy’s Office of Science.
The U.S. Department of Energy’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit https://energy.gov/science.
