Phonons Shield Qubits for Quantum Leap | Science News
Harvard scientists have cracked a major hurdle in quantum computing by using sound waves—called phonons—to shield fragile qubits, tripling their ability to maintain quantum states. By wrapping diamond-based qubits in continuous mechanical vibrations, they’ve created “all-mechanical coherence protection,” making qubits far less susceptible to environmental noise. This breakthrough not only boosts reliability but also enables phonons to serve dual roles: protecting quantum data while potentially transmitting it across chips. The result? Smaller, more efficient quantum networks built directly…
