Quantum computers can now spot their own mistakes as they happen
Recent breakthroughs in quantum error correction allow sensitive processors to detect and fix internal errors in real-time, overcoming the primary hurdle to building reliable, large-scale supercomputers.
Researchers have successfully demonstrated quantum error correction, a vital process where a system identifies its own calculation slips without crashing. Quantum bits, or qubits, are notoriously fragile and can be disrupted by the slightest heat or vibration. By grouping qubits together into logical units, these systems can now monitor for changes and correct them instantly.
