Constant-Overhead Fault-Tolerant Quantum Computation with Reconfigurable Atom Arrays
Qian Xu, J. Pablo Bonilla Ataides, Christopher A. Pattison +7
Quantum low-density parity-check (qLDPC) codes can achieve high encoding rates and good code distance scaling, providing a promising route to low-overhead fault-tolerant quantum co…
Hierarchical memories: Simulating quantum LDPC codes with local gates
Christopher A. Pattison, Anirudh Krishna, John Preskill
Constant-rate low-density parity-check (LDPC) codes are promising candidates for constructing efficient fault-tolerant quantum memories. However, if physical gates are subject to g…
An efficient decoder for a linear distance quantum LDPC code
Shouzhen Gu, Christopher A. Pattison, Eugene Tang
Recent developments have shown the existence of quantum low-density parity check (qLDPC) codes with constant rate and linear distance. A natural question concerns the efficient dec…
Fast Arbitrary Precision Floating Point on FPGA
Johannes de Fine Licht, Christopher A. Pattison, Alexandros Nikolaos Ziogas +2
Numerical codes that require arbitrary precision floating point (APFP) numbers for their core computation are dominated by elementary arithmetic operations due to the super-linear…
Improved quantum error correction using soft information
Christopher A. Pattison, Michael E. Beverland, Marcus P. da Silva +1
The typical model for measurement noise in quantum error correction is to randomly flip the binary measurement outcome. In experiments, measurements yield much richer information -…
Inflation: a quantum laboratory on cosmological scales
Chris Pattison
This thesis is dedicated to studying cosmological inflation, which is a period of accelerated expansion in the very early Universe that is required to explain the observed anisotro…
