Quantum LDPC codes with design rate 1/5 and good performance below 1000 physical qubits
Yifan Hong
Constant-rate quantum low-density parity-check (LDPC) codes promise fault-tolerant quantum computation with constant spatial overhead in the asymptotic limit. Nonetheless, discover…
Decision-Making under Combinatorial Risk
Yifan Hong, Hongmiao Fan, Chen Wang
Decision-making under risk is typically studied through single-shot lottery choices. Yet many real decisions involve combinatorial risk, where risk arises from multiple risky compo…
Towards self-correcting quantum codes for neutral atom arrays
Jinkang Guo, Yifan Hong, Adam Kaufman +1
Discovering low-overhead quantum error-correcting codes is of significant interest for fault-tolerant quantum computation. For hardware capable of long-range connectivity, the biva…
Entangling four logical qubits beyond break-even in a nonlocal code
Yifan Hong, Elijah Durso-Sabina, David Hayes +1
Quantum error correction protects logical quantum information against environmental decoherence by encoding logical qubits into entangled states of physical qubits. One of the most…
Quantum memory at nonzero temperature in a thermodynamically trivial system
Yifan Hong, Jinkang Guo, Andrew Lucas
Passive error correction protects logical information forever in the thermodynamic limit by updating the system based only on local information and few-body interactions. A paradig…
Long-range-enhanced surface codes
Yifan Hong, Matteo Marinelli, Adam M. Kaufman +1
The surface code is a quantum error-correcting code for one logical qubit, protected by spatially localized parity checks in two dimensions. Due to fundamental constraints from spa…
