Preserving MWPM-Decodability in Fault-Equivalent Rewrites
Maximilian Schweikart, Linnea Grans-Samuelsson, Aleks Kissinger +1
Decoding a quantum error correction code is generally NP-hard, but corrections must be applied at a high frequency to suppress noise successfully. Matchable codes, like the surface…
A partition function framework for estimating logical error curves in stabilizer codes
Leon Wichette, Hans Hohenfeld, Elie Mounzer +1
Based on the mapping between stabilizer quantum error correcting codes and disordered statistical mechanics models, we define a ratio of partition functions that measures the succe…
Demonstration of logical qubits and repeated error correction with better-than-physical error rates
A. Paetznick, M. P. da Silva, C. Ryan-Anderson +29
The promise of quantum computers hinges on the ability to scale to large system sizes, e.g., to run quantum computations consisting of more than 100 million operations fault-tolera…
A fault-tolerant pairwise measurement-based code on eight qubits
Linnea Grans-Samuelsson, David Aasen, Parsa Bonderson
We construct a pairwise measurement-based code on eight qubits that is error correcting for circuit noise, with fault distance 3. The code can be implemented on a subset of a recta…
Improved Pairwise Measurement-Based Surface Code
Linnea Grans-Samuelsson, Ryan V. Mishmash, David Aasen +5
We devise a new realization of the surface code on a rectangular lattice of qubits utilizing single-qubit and nearest-neighbor two-qubit Pauli measurements and three auxiliary qubi…
