High-threshold and Low-overhead Fault-tolerant Quantum Memory

Join a Qiskit Quantum Seminar featuring Patrick Rall as he presents groundbreaking research on fault-tolerant quantum memory protocols. Explore an innovative end-to-end quantum error correction protocol based on LDPC codes that achieves a remarkable 0.8% error threshold, rivaling the long-standing surface code standard. Learn how this protocol requires only n ancillary qubits and a depth-7 circuit with nearest-neighbor CNOT gates, demonstrating impressive efficiency with a degree-6 graph connectivity. Discover how 12 logical qubits can be preserved for ten million syndrome cycles using just 288 physical qubits at a 0.1% error rate - a significant improvement over surface code requirements. Understand the practical implications of this research for near-term quantum processors and the future of fault-tolerant quantum computation, presented by IBM Quantum research staff member Patrick Rall, who brings his expertise from Caltech and the University of Texas at Austin.
