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…
A Rational Model of Dimension-reduced Human Categorization
Yifan Hong, Chen Wang
Humans can categorize with only a few samples despite the numerous features. To mimic this ability, we propose a novel dimension-reduced category representation using a mixture of…
Locality and error correction in quantum dynamics with measurement
Aaron J. Friedman, Chao Yin, Yifan Hong +1
The speed of light sets a strict upper bound on the speed of information transfer in both classical and quantum systems. In nonrelativistic quantum systems, the Lieb-Robinson T…
Quantum error correction in a time-dependent transverse field Ising model
Yifan Hong, Jeremy T. Young, Adam M. Kaufman +1
We describe a simple quantum error correcting code built out of a time-dependent transverse field Ising model. The code is similar to a repetition code, but has two advantages: an…
Fast high-fidelity multi-qubit state transfer with long-range interactions
Yifan Hong, Andrew Lucas
We describe an efficient protocol to perform quantum state transfer using Hamiltonian dynamics with long-range interactions. The time to transfer qubits a sufficiently large di…
Hierarchy of linear light cones with long-range interactions
Minh C. Tran, Chi-Fang Chen, Adam Ehrenberg +6
In quantum many-body systems with local interactions, quantum information and entanglement cannot spread outside of a linear light cone, which expands at an emergent velocity analo…
