Complementary 3D color codes for transversal quantum logic
Friederike Butt, Luis Colmenarez, Erik Weilandt +3
Transversal logical gates provide a direct route to fault-tolerant quantum computation, but the Eastin-Knill theorem forbids a universal transversal gate set within a single quantu…
Machine Learning Optimal Quantum Error Correction Thresholds
Dominik Seip, Luis Colmenarez, Markus Schmitt +1
As quantum computers remain susceptible to noise, QEC is essential for preserving logical information during computations. However, the performance of QEC codes breaks down beyond…
Lattice surgery for near-term experimental logical qubit entanglement creation in planar architectures
Lukas Bödeker, Ãron Márton, Luis Colmenarez +3
In the era of early fault-tolerant quantum computing, basic demonstrations of entanglement operations between a few logical qubits are at the frontier of recent developments in qua…
Syndrome resampling enhances quantum error correction thresholds
Luis Colmenarez, Ãron Márton, Markus Müller
Quantum error correction (QEC) enables fault-tolerant quantum computation but requires operating quantum hardware at physical error rates below code-dependent thresholds, which rem…
Unitary fault-tolerant encoding of Pauli states in surface codes
Luis Colmenarez, Remmy Zen, Jan Olle +2
In fault-tolerant quantum computation, the preparation of logical states is a ubiquitous subroutine, yet significant challenges persist even for the simplest states required. In th…
Addressable fault-tolerant universal quantum gate operations for high-rate lift-connected surface codes
Josias Old, Juval Bechar, Markus Müller +1
Quantum low-density parity check (qLDPC) codes are among the leading candidates to realize error-corrected quantum memories with low qubit overhead. Potentially high encoding rates…
