Constant-Time Surgery on 2D Hypergraph Product Codes with Near-Constant Space Overhead
Kathleen Chang, Zhiyang He, Theodore J. Yoder +2
Generalized code surgery is a versatile and low-overhead technique for performing fault-tolerant computation on quantum low-density parity-check (qLDPC) codes. In many settings, su…

Fast and fault-tolerant logical measurements: Auxiliary hypergraphs and transversal surgery
Alexander Cowtan, Zhiyang He, Dominic J. Williamson +1
Quantum code surgery is a promising technique to perform fault-tolerant computation on quantum low-density parity-check codes. Recent developments have significantly reduced the sp…

Universal adapters between quantum LDPC codes
Esha Swaroop, Tomas Jochym-O'Connor, Theodore J. Yoder
We propose the repetition code adapter as a way to perform joint logical Pauli measurements within a quantum low-density parity check (LDPC) codeblock or between separate such code…
