Quantum Computing Breakthrough Opens a New Path to Larger, More Powerful Processors

Keeping silicon quantum bits accurate while they work together could help turn established chipmaking technology into larger quantum computers capable of tackling increasingly complex problems.

Silicon spin qubits offer that possibility, but the precision they achieve on their own can slip when several are controlled at once.

In silicon spin qubits, information is encoded in the spin of an electron trapped in a silicon substrate.

Fidelity measures how accurately a quantum operation is performed.

With the new protocol, fidelities stayed above 99.99% when up to three qubits operated at the same time.
