US 2026/0195629 A1 · MECHANICALLY MEDIATED QUANTUM SYSTEMS

Abstract

Systems and methods relate to mechanically mediated coupling of qubits to a mechanical resonator. Individual qubits can be coupled to a mechanical resonator, which can in turn couple to a second qubit that is separated from the first in distance, time, or both. Such mechanically mediated coupling can produce entangled qubit states over long distances and timescales. Arrays of qubits and/or mechanical resonators can be used to scale mechanically mediated coupling to larger numbers of qubits.
