Beam search decoder for quantum LDPC codes
Min Ye, Dave Wecker, Nicolas Delfosse
We propose a decoder for quantum low density parity check (LDPC) codes based on a beam search heuristic guided by belief propagation (BP). Our beam search decoder applies to all qu…
Advantage in distributed quantum computing with slow interconnects
Evan E Dobbs, Nicolas Delfosse, Aharon Brodutch
The main bottleneck for distributed quantum computing is the rate at which entanglement is produced between quantum processing units (QPUs). In this work, we prove that multiple QP…
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…
Correction of chain losses in trapped ion quantum computers
Nolan J. Coble, Min Ye, Nicolas Delfosse
Neutral atom quantum computers and to a lesser extent trapped ions may suffer from atom loss. In this work, we investigate the impact of atom loss in long chains of trapped ions. E…
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…
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…
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…
Optimizing hypergraph product codes with random walks, simulated annealing and reinforcement learning
Bruno C. A. Freire, Nicolas Delfosse, Anthony Leverrier
Hypergraph products are quantum low-density parity-check (LDPC) codes constructed from two classical LDPC codes. Although their dimension and distance depend only on the parameters…
