Patchwork: automated lattice surgery and space-time partitioning for real-time decoding
Christopher Chamberland, Muyuan Li, Scott Thornton +3
We introduce patchwork, a lattice-surgery compiler for arbitrary multi-qubit Pauli measurements on a prescribed narrow-corridor two-dimensional surface-code layout. Systematic geom…
An almost-linear time decoding algorithm for quantum LDPC codes under circuit-level noise
Antonio deMarti iOlius, Imanol Etxezarreta Martinez, Joschka Roffe +1
Fault-tolerant quantum computers must be designed in conjunction with classical co-processors that decode quantum error correction measurement information in real-time. In this wor…
Quantum CSS Duadic and Triadic Codes: New Insights and Properties
Reza Dastbasteh, Olatz Sanz Larrarte, Josu Etxezarreta Martinez +3
In this study, we investigate the construction of quantum CSS duadic codes with dimensions greater than one. We introduce a method for extending smaller splittings of quantum duadi…
The closed-branch decoder for quantum LDPC codes
Antonio deMarti iOlius, Josu Etxezarreta Martinez
Quantum error correction is the building block for constructing fault-tolerant quantum processors that can operate reliably even if its constituting elements are corrupted by decoh…
Decoding algorithms for surface codes
Antonio deMarti iOlius, Patricio Fuentes, Román Orús +2
Quantum technologies have the potential to solve certain computationally hard problems with polynomial or super-polynomial speedups when compared to classical methods. Unfortunatel…
The superadditivity effects of quantum capacity decrease with the dimension for qudit depolarizing channels
Josu Etxezarreta Martinez, Antonio deMarti iOlius, Pedro M. Crespo
Quantum channel capacity is a fundamental quantity in order to understand how good can quantum information be transmitted or corrected when subjected to noise. However, it is gener…
Performance enhancement of surface codes via recursive MWPM decoding
Antonio deMarti iOlius, Josu Etxezarreta Martinez, Patricio Fuentes +1
The minimum weight perfect matching (MWPM) decoder is the standard decoding strategy for quantum surface codes. However, it suffers a harsh decrease in performance when subjected t…
Performance of surface codes in realistic quantum hardware
Antonio deMarti iOlius, Josu Etxezarreta Martinez, Patricio Fuentes +2
Surface codes are generally studied based on the assumption that each of the qubits that make up the surface code lattice suffers noise that is independent and identically distribu…
