Chutes and Ladders: Dynamical Automorphisms via the ZX-Calculus
Alexander Frei, Sascha Zakaib-Bernier, Zachary Mann +2
The ZX-calculus is a powerful graphical language for manipulating quantum circuits, which has recently found many applications in quantum error correction. We extend this language…
Simplified circuit-level decoding using Knill error correction
Ewan Murphy, Subhayan Sahu, Michael Vasmer
Quantum error correction will likely be essential for building a large-scale quantum computer, but it comes with significant requirements at the level of classical control software…
Scalable Simulation of Fermionic Encoding Performance on Noisy Quantum Computers
Emiliia Dyrenkova, Raymond Laflamme, Michael Vasmer
A compelling application of quantum computers with thousands of qubits is quantum simulation. Simulating fermionic systems is both a problem with clear real-world applications and…
Single-shot and measurement-based quantum error correction via fault complexes
Timo Hillmann, Guillaume Dauphinais, Ilan Tzitrin +1
Photonics provides a viable path to a scalable fault-tolerant quantum computer. The natural framework for this platform is measurement-based quantum computation, where fault-tolera…
Fault-tolerant transformations of spacetime codes
Arthur Pesah, Austin K. Daniel, Ilan Tzitrin +1
Recent advances in quantum error-correction (QEC) have shown that it is often beneficial to understand fault-tolerance as a dynamical process, a circuit with redundant measurements…
Implementing fault-tolerant non-Clifford gates using the [[8,3,2]] color code
Daniel Honciuc Menendez, Annie Ray, Michael Vasmer
Quantum computers promise to solve problems that are intractable for classical computers, but qubits are vulnerable to many sources of error, limiting the depth of the circuits tha…
