Reducing Decoding Latency in Quantum Error Correction by Early Starting Clustering
Tommaso Peduzzi, Lukas Bödeker, Markus Müller +1
In quantum error correction, fast low-latency decoding is essential for fault-tolerant quantum computation, as delays in processing syndrome data can lead to the backlog problem. E…
Hierarchy of Rényi Coherent Information in Stabilizer Codes
Akash Vijay, Luis Colmenarez, Jong Yeon Lee
Rényi coherent information, a computable proxy for the von Neumann coherent information, is widely used to study mixed-state phases of matter and decodability transitions in noisy…

Lukas Bödeker, Luis Colmenarez, Sergey Blinov +3
Low-overhead quantum error-correction schemes are essential for enabling quantum computation on registers containing multiple logical qubits. For planar architectures with limited…
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…
Syndrome resampling enhances quantum error correction thresholds
Luis Colmenarez, Áron 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…
Lattice surgery-based logical state teleportation via noisy links
Áron Márton, Luis Colmenarez, Lukas Bödeker +1
For planar architectures surface code-based quantum error correction is one of the most promising approaches to fault-tolerant quantum computation. This is partially due to the var…
Realizing Lattice Surgery on Two Distance-Three Repetition Codes with Superconducting Qubits
Ilya Besedin, Michael Kerschbaum, Jonathan Knoll +12
Quantum error correction is needed for quantum computers to be capable of fault-tolerantly executing algorithms using hundreds of logical qubits. Recent experiments have demonstrat…
Coherent information as a mixed-state topological order parameter of fermions
Ze-Min Huang, Luis Colmenarez, Markus Müller +1
Quantum error correction protects quantum information against decoherence provided the noise strength remains below a critical threshold. This threshold marks the critical point fo…
Fundamental thresholds for computational and erasure errors via the coherent information
Luis Colmenarez, Seyong Kim, Markus Müller
Quantum error correcting (QEC) codes protect quantum information against environmental noise. Computational errors caused by the environment change the quantum state within the qub…
Quantum Circuit Discovery for Fault-Tolerant Logical State Preparation with Reinforcement Learning
Remmy Zen, Jan Olle, Luis Colmenarez +3
The realization of large-scale quantum computers requires not only quantum error correction (QEC) but also fault-tolerant operations to handle errors that propagate into harmful er…
Accurate optimal quantum error correction thresholds from coherent information
Luis Colmenarez, Ze-Min Huang, Sebastian Diehl +1
Quantum error correcting (QEC) codes protect quantum information from decoherence, as long as error rates fall below critical error thresholds. In general, obtaining thresholds imp…
