Quantum Computing Enters Steampunk Era with First Mechanical Qubit

Physicists at ETH Zürich have developed the first fully mechanical qubit, using a piezoelectric disk on a sapphire base as a mechanical resonator, coupled with a superconducting qubit. This innovation addresses the short-lived nature of virtual qubits by providing longer coherence times, potentially improving quantum computing capabilities. The team plans to enhance these times further and test the qubits with quantum gates.
