Thermal Throttling of Quantum State Transfer
Twesh Upadhyaya, T. C. Mooney, Yifan Hong +1
Quantum state transfer on qubit lattices is a crucial step in a panoply of quantum information processing tasks. Understanding its fundamental limits in the presence of practical i…
Spatial overhead reduction for 2D hypergraph product codes
Aarav Pabla, Yu-Xin Wang, Yifan Hong
The hypergraph product creates a quantum stabilizer code from two input classical linear codes; a paradigmatic example being the surface code as a hypergraph product of two classic…
Robustness-Runtime Tradeoff for Quantum State Transfer
Twesh Upadhyaya, Yifan Hong, T. C. Mooney +1
Quantum state transfer is the primitive of transporting an unknown state on one site of a lattice to another. Using power-law interactions, recent state transfer protocols achieve…
Single-shot preparation of hypergraph product codes via dimension jump
Yifan Hong
Quantum error correction is a fundamental primitive of fault-tolerant quantum computing. But in order for error correction to proceed, one must first prepare the codespace of the u…
Quantum teleportation implies symmetry-protected topological order
Yifan Hong, David T. Stephen, Aaron J. Friedman
We constrain a broad class of teleportation protocols using insights from locality. In the "standard" teleportation protocols we consider, all outcome-dependent unitaries are Pauli…
