Lattice surgery with Bell measurements: Modular fault-tolerant quantum computation at low entanglement cost
Trond Hjerpekjøn Haug, Timo Hillmann, Anton Frisk Kockum +1
Modular architectures are a promising approach to scaling quantum computers to fault tolerance. Small, low-noise quantum processors connected through relatively noisy quantum links…
Sequential decoding of the XYZ hexagonal stabilizer code
Basudha Srivastava, Yinzi Xiao, Anton Frisk Kockum +2
Quantum error correction requires accurate and efficient decoding to optimally suppress errors in the encoded information. For concatenated codes, where one code is embedded within…
Detecting quantum speedup of random walks with machine learning
Hanna Linn, Yu Zheng, Anton Frisk Kockum
We explore the use of machine-learning techniques to detect quantum speedup in random walks on graphs. Specifically, we investigate the performance of three different neural-networ…
The XYZ hexagonal stabilizer code
Basudha Srivastava, Anton Frisk Kockum, Mats Granath
We consider a topological stabilizer code on a honeycomb grid, the "XYZ" code. The code is inspired by the Kitaev honeycomb model and is a simple realization of a "matching cod…
Error-rate-agnostic decoding of topological stabilizer codes
Karl Hammar, Alexei Orekhov, Patrik Wallin Hybelius +4
Efficient high-performance decoding of topological stabilizer codes has the potential to crucially improve the balance between logical failure rates and the number and individual e…
Designing frequency-dependent relaxation rates and Lamb shift for a giant artificial atom
Anton Frisk Kockum, Per Delsing, Göran Johansson
In traditional quantum optics, where the interaction between atoms and light at optical frequencies is studied, the atoms can be approximated as point-like when compared to the wav…
