One-Shot any Code
Andrew C. Yuan
We first provide a simple proof showing that any single-shot code is self-correcting. We then show that any CSS quantum low-density parity-check (QLDPC) code can be trans…
Non-CSS Quantum Code Embedding
Andrew C. Yuan, Nouédyn Baspin
We generalize the unified framework in [Phys. Rev. A 113, 022438 (2026)] to accommodate arbitrary stabilizer codes (referred as non-CSS for emphasis). The generalization has immedi…
4D and 5D Layer Codes through Color Routing
Andrew C. Yuan, Nouédyn Baspin
We introduce and explicit Calderbank-Shor-Steane (CSS) code construction that generalizes the Layer codes to dimensions. Much like its predecessor, the present construction…
Parsimonious Quantum Low-Density Parity-Check Code Surgery
Andrew C. Yuan, Alexander Cowtan, Zhiyang He +2
Quantum code surgery offers a flexible, low-overhead framework for executing logical measurements within quantum error-correcting codes. It encompasses several fault-tolerant logic…
Quantum Weight Reduction with Layer Codes
Andrew C. Yuan, Nouédyn Baspin, Dominic J. Williamson
Quantum weight reduction procedures ease the implementation of quantum codes by sparsifying them, resulting in low-weight checks and low-degree qubits. However, to date, only few q…
Unified Framework for Quantum Code Embedding
Andrew C. Yuan
Given a Calderbank-Shor-Steane (CSS) code, it is sometimes necessary to modify the code by adding an arbitrary number of physical qubits and parity checks. Motivations may include…
Phase sensitive information from a planar Josephson junction
Andrew C. Yuan, Steven A. Kivelson
Josephson tunneling across a planar junction generally depends on the relative twist angle, , between the two layers. However, if under a discrete rotation, the order parameter…
Exactly Solvable Model of Randomly Coupled Twisted Superconducting Bilayers
Andrew C. Yuan
Motivated by recent experiments on twisted junctions of cuprate superconductors (SC), it was proposed [1] that at zero temperature, a random first order Josephson coupling $J_1(\te…
Absence of Floating Phase in Superconductors with Time-reversal Symmetry Breaking on any Lattice
Andrew C. Yuan
Due to the interplay of multi-component order parameters (e.g., a twisted bilayer superconductor with inter-layer Josephson coupling or a frustrated ()-band superconductor)…
Inhomogeneity-Induced Time-Reversal Symmetry Breaking in Cuprate Twist-Junctions
Andrew C. Yuan, Yaar Vituri, Erez Berg +2
The lowest order Josephson coupling, , between two d-wave superconductors with phase-difference across the junction vanishes when their relative orientation is r…
Multiband mean-field theory of the superconductivity scenario in SrRuO
Andrew C. Yuan, Erez Berg, Steven A. Kivelson
Many seemingly contradictory experimental findings concerning the superconducting state in SrRuO can be accounted for on the basis of a conjectured accidental degeneracy be…
Strain-induced time reversal breaking and half quantum vortices near a putative superconducting tetra-critical point in SrRuO
Andrew C. Yuan, Erez Berg, Steven A. Kivelson
It has been shown [1] that many seemingly contradictory experimental findings concerning the superconducting state in SrRuO can be accounted for as resulting from the exist…
Realizing Artin-Schreier Covers with Minimal -numbers in Positive Characteristic
Fiona Abney-McPeek, Hugo Berg, Jeremy Booher +8
Suppose is a smooth projective connected curve defined over an algebraically closed field of characteristic and is a finite, possibly empty, set of points.…
A proposal for reconciling diverse experiments on the superconducting state in Sr2RuO4
Steven A. Kivelson, Andrew C. Yuan, B. J. Ramshaw +1
A variety of precise experiments have been carried out to establish the character of the superconducting state in Sr2RuO4. Many of these appear to imply contradictory conclusions c…
