Asymptotically good CSS codes that realize the logical transversal Clifford group fault-tolerantly
K. Sai Mineesh Reddy, Navin Kashyap·Jan 13, 2026
This paper introduces a framework for constructing Calderbank-Shor-Steane (CSS) codes that support fault-tolerant logical transversal $Z$-rotations. Using this framework, we obtain asymptotically good CSS codes that fault-tolerantly realize the logic...
Symmetry-Adapted State Preparation for Quantum Chemistry on Fault-Tolerant Quantum Computers

Zhi-Hai Liu, Xiao-Fei Liu, H. Q. Xu +5 more·Jan 13, 2026
By utilizing the site-dependent spin quantization axis in semiconductor quantum dot (QD) arrays, shuttling-based spin qubit gates have become an appealing approach to realize scalable quantum computing due to the circumvention of using high-frequency...
Data-driven learning of non-Markovian quantum dynamics
Samuel Goodwin, Brian K. McFarland, Manuel H. Muñoz-Arias +6 more·Jan 12, 2026
Fault-tolerant quantum computing requires extremely precise knowledge and control of qubit dynamics during the application of a gate. We develop a data-driven learning protocol for characterizing quantum gates that builds off previous work on learnin...

This note bridges the gap between theoretical second quantization and practical quantum hardware by detailing the Jordan-Wigner mapping for the Unitary Coupled Cluster Singles and Doubles (UCCSD) ansatz. Using the hydrogen molecule in a minimal basis...
Fault-tolerant modular quantum computing with surface codes using single-shot emission-based hardware
Siddhant Singh, Rikiya Kashiwagi, Kazufumi Tanji +4 more·Jan 12, 2026
Fault-tolerant modular quantum computing requires stabilizer measurements across the modules in a quantum network. For this, entangled states of high quality and rate must be distributed. Currently, two main types of entanglement distribution protoco...
Nonadiabatic theory for subcycle ionic dynamics in multielectron tunneling ionization

Guanyu Zhu, Ryohei Kobayashi, Po-Shen Hsin·Jan 11, 2026
A fundamental problem of fault-tolerant quantum computation with quantum low-density parity-check (qLDPC) codes is the tradeoff between connectivity and universality. It is widely believed that in order to perform native logical non-Clifford gates, o...
