Tiny sound waves could help solve a major quantum computing problem

It may also help enable hybrid quantum systems that combine several different kinds of quantum bits, or qubits.

Using Sound to Carry Quantum Information One promising approach to quantum networking uses the spin of an electron, associated with impurity in diamond, to store quantum information.

The Challenge of Preserving Quantum Memory Using phonons, however, creates a major difficulty: protecting quantum memory.

They could transport quantum information between different parts of a network while simultaneously helping protect that information from environmental noise.

The result demonstrates that continuous-wave mechanical noise suppression can extend quantum coherence in real devices, suggesting that microscopic sound waves could become an important tool for building more reliable and compact quantum systems.
