Why adding more qubits actually reduced errors in a major quantum breakthrough
Google researchers demonstrated that increasing the number of physical qubits in a system can paradoxically lower the overall error rate, overcoming a fundamental hurdle in building reliable quantum computers.
Quantum computers are notoriously fragile because subatomic particles lose information when disturbed by heat or light. In 2023, Google scientists proved that by spreading information across a larger group of physical qubits to create a single logical qubit, they could suppress these errors.
