Overview
Quantum error correction (QEC) is the cornerstone of fault-tolerant quantum computing. Without robust error correction, quantum computers cannot scale beyond noisy intermediate-scale quantum (NISQ) devices to achieve practical quantum advantage.
My research program has pioneered multiple breakthrough directions in QEC, from the foundational theory of entanglement-assisted quantum error correction to the recent construction of good quantum LDPC codes with linear-time decoders. Our work addresses both the theoretical foundations and practical implementation challenges of building reliable quantum computers.
The significance of this research was recognized through publications in Science, Nature Physics, Nature Communications, and STOC, with our seminal 2006 Science paper on entanglement-assisted QEC accumulating over 550 citations and establishing a new paradigm for constructing quantum codes from classical codes.
Research Goals
- Construct asymptotically good quantum codes — Develop quantum error-correcting codes with constant rate and linear distance, enabling efficient encoding of logical qubits
- Achieve linear-time decoding — Design efficient decoding algorithms that scale linearly with code size, crucial for practical real-time error correction
- Minimize fault-tolerance overhead — Reduce the physical qubit overhead for fault-tolerant quantum computation through constant-overhead magic state distillation and optimized code constructions
- Enable practical implementation — Bridge theory and experiment by developing codes compatible with realistic hardware constraints and noise models
