QUANTUM ACOUSTICS

Good vibrations for quantum computing

Nature Physics (2022)Cite this article

Subjects

Quantum computing operations are realized using acoustic devices, paving the way for a new type of quantum processor.

Quantum computers promise to exponentially speed up a range of important and highly challenging computational tasks1. However, their physical architectures are complex, the quantum states they rely on are fragile, and computing operations with them are sensitive to errors. Parallel experiments reported by Alex Wollack and colleagues2 in Nature and Uwe von Lüpke and colleagues3 in Nature Physics have now shown that quantum computing operations can be performed with acoustic devices. This approach promises to suppress key error pathways and allow quantum states to be protected from their environments for far longer. As such, it represents significant progress towards robust quantum computing.
