Quantum computers require memories that are capable of storing quantum information
reliably for long periods of time. The surface code is a two-dimensional quantum memory …

In this paper, we introduce the gauge-fixed QLDPC surgery scheme, an improved logical
measurement scheme based on the construction of Cohen et al.~(Sci.~ Adv.~ 8, eabn1717) …

We introduce homological measurement, a framework for measuring the logical Pauli
operators encoded in CSS stabilizer codes. The framework is based on the algebraic …

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 …

Quantum error correction plays a prominent role in the realization of quantum computation,
and quantum low-density parity-check (qLDPC) codes are believed to be practically useful …

Quantum error correction is a fundamental primitive of fault-tolerant quantum computing. But
in order for error correction to proceed, one must first prepare the codespace of the …

We present a new family of quantum low-density parity-check codes, which we call radial
codes, obtained from the lifted product of a specific subset of classical quasi-cyclic codes …

Quantum information is fragile and must be protected by a quantum error-correcting code for
large-scale practical applications. Recently, highly efficient quantum codes have been …
