Major Breakthrough in Quantum Error Correction
Scientists achieve 99.9% fidelity in quantum error correction, bringing fault-tolerant quantum computing closer to reality.
The Challenge of Quantum Errors
Quantum computers are inherently fragile. Quantum states can be easily disrupted by environmental noise, leading to computational errors. This has been one of the biggest obstacles to practical quantum computing.
