SUMMARY:Applied Physics/Physics Colloquium: Robert Huang - "High-rate qLDPC processors"
DESCRIPTION:Abstract: Despite significant progress on quantum low-density parity-check (qLDPC) codes\, building qLDPC processors that are high-rate\, high-throughput\, hardware-friendly\, and fast-to-decode remains a challenge. We introduce mitten codes\, a family of qLDPC processor codes of encoding rate 20% and check weight 9\, based on non-abelian groups. Their non-abelian structure evades distance bounds constraining abelian counterparts\, allowing mitten codes to reach distance 18 and beyond with just a few hundred data qubits. The logical operators of a mitten code are related by the group action\, yielding
