phononic links

The phononic links tag covers research into Quantum Phononic Links, a proposed on-chip method for connecting distant semiconductor qubits. The architecture uses controlled lattice vibrations, or phonons, as a quantum bus for hole-spin qubits in strained germanium-on-silicon. Recent discussions focus on work from the University of Warwick, Canada’s National Research Council, and collaborators, including an APL Quantum paper describing a potential route toward wafer-scale quantum computing. The proposal addresses how non-neighbouring qubits might interact without a separate interconnect layer or extensive additional control hardware. Coverage emphasizes the design’s possible applications and scaling goals while noting that it remains a theoretical architecture rather than a demonstrated million-qubit processor.
