Abstract
Official abstract text for this publication.
Systems and methods are provided for generating at least one high fidelity resource state. A classical code and punctured to provide a first set of generators and a second set of generators. The first set of generators is mapped to a set of stabilizer generators, and the second set of generators is mapped to a set of logical operators. A set of resource states are prepared in physical qubits. A decoding process is performed on the resource states according to a quantum code represented by the set of stabilizer generators and the set of logical operators, and qubits corresponding to the stabilizers are measured.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for generating at least one high fidelity resource state, the method comprising: selecting a classical code in which all of the codewords associated with the code have a weight of zero mod 2g, where g is a positive integer power of two; puncturing the classical code such that a first set of generators retains a weight of zero mod 2g and a second set of generators has a weight of 2g−1 mod 2g; mapping the first set of generators to a set of stabil…
