Breakeven demonstration of quantum low-density parity-check codes
Edwin Tham, Michael L. Goldman, Shantanu Debnath +8
High-rate quantum low-density parity-check (qLDPC) codes are a leading candidate for fault-tolerant quantum computing. They feature higher encoding rates than planar alternatives s…
Cyclic Hypergraph Product Code
Arda Aydin, Nicolas Delfosse, Edwin Tham
Hypergraph product (HGP) codes are one of the most popular family of quantum low-density parity-check (LDPC) codes. Circuit-level simulations show that they can achieve the same lo…
Recursive Clifford noise reduction
Aharon Brodutch, Gregory Baimetov, Edwin Tham +1
Clifford noise reduction (CliNR) is a partial error correction scheme that reduces the logical error rate of Clifford circuits at the cost of a modest qubit and gate overhead. The…
Optimized Clifford Noise Reduction: Theory, Simulations and Experiments
Edwin Tham, Nicolas Delfosse
We propose several optimizations of the CliNR partial error correction scheme which implements Clifford circuits by consuming a resource state. Errors are corrected by measuring a…
Distributed fault-tolerant quantum memories over a 2xL array of qubit modules
Edwin Tham, Min Ye, Ilia Khait +2
We propose an architecture for a quantum memory distributed over a array of modules equipped with a cyclic shift implemented via flying qubits. The logical information…
