Splitting decoders for correcting hypergraph faults
Nicolas Delfosse, Adam Paetznick, Jeongwan Haah +1
The surface code is one of the most popular quantum error correction codes. It comes with efficient decoders, such as the Minimum Weight Perfect Matching (MWPM) decoder and the Uni…
Fault-Tolerant Hastings-Haah Codes in the Presence of Dead Qubits
David Aasen, Jeongwan Haah, Parsa Bonderson +2
We develop protocols for Hastings-Haah Floquet codes in the presence of dead qubits.
Measurement Quantum Cellular Automata and Anomalies in Floquet Codes
David Aasen, Jeongwan Haah, Zhi Li +1
We investigate the evolution of quantum information under Pauli measurement circuits. We focus on the case of one- and two-dimensional systems, which are relevant to the recently i…
Query-optimal estimation of unitary channels in diamond distance
Jeongwan Haah, Robin Kothari, Ryan O'Donnell +1
We consider process tomography for unitary quantum channels. Given access to an unknown unitary channel acting on a -dimensional qudit, we aim to output a classical des…
