Dynamical codes for hardware with noisy readouts
Peter-Jan H. S. Derks, Alex Townsend-Teague, Jens Eisert +3
Dynamical stabilizer codes may offer a practical route to large-scale quantum computation. Such codes are defined by a schedule of error-detecting measurements, which allows for fl…
Witness expansion: A unified framework for analytical and measurable mixed-state resource detection
Yifan Tang, Chengkai Zhu, Yuzhen Zhang +6
Quantum information science aims to harness different kinds of quantum resources to accomplish specific information-processing tasks. These resources also play an increasingly impo…
Nearest-neighbour gates are all you need: High-rate quantum low-density parity-check codes on a planar grid
Boren Gu, Tamas Noszko, Vincent Steffan +4
High-performance quantum low-density parity-check codes promise substantial reductions in the overhead of fault-tolerant quantum computation, but most constructions require long-ra…
Designing fault-tolerant circuits using detector error models
Peter-Jan H. S. Derks, Alex Townsend-Teague, Ansgar G. Burchards +1
Quantum error-correcting codes, such as subspace, subsystem, and Floquet codes, are typically constructed within the stabilizer formalism, which does not fully capture the idea of…
Localized statistics decoding for quantum low-density parity-check codes
Timo Hillmann, Lucas Berent, Armanda O. Quintavalle +3
Quantum low-density parity-check codes are a promising candidate for fault-tolerant quantum computing with considerably reduced overhead compared to the surface code. However, the…
Hardware-tailored logical Clifford circuits for stabilizer codes
Eric J. Kuehnke, Kyano Levi, Joschka Roffe +2
Quantum error correction is the art of protecting fragile quantum information through suitable encoding and active interventions. After encoding logical qubits into physi…
