Quantum Error Correction & Decoherence
One of the biggest challenges in quantum computing is maintaining the stability of qubits. Quantum error correction (QEC) is essential to preserving quantum states against decoherence.
Challenges in Quantum Error Correction
- Decoherence: Quantum states are fragile and susceptible to environmental interference.
- Surface Code Implementation: Google demonstrated scalable logical qubits to reduce error rates.
- Low-Density Parity-Check (LDPC) Codes: Reduces qubit overhead while maintaining fault tolerance.
- Logical Qubit Stability: Research focuses on extending coherence times for reliable quantum computations.
Future of Quantum Error Correction
As quantum hardware scales, QEC methods must evolve to enable fault-tolerant quantum computation. Future developments will integrate real-time error correction into quantum processors.
