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, Áron 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…
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…
