Unlocking early fault-tolerant quantum computing with mitigated magic dilution

Surabhi Luthra, Alexandra E. Moylett, Dan E. Browne, Earl T. Campbell • Published: 2025-05-15
As quantum computing progresses towards the early fault-tolerant regime, quantum error correction will play a crucial role in protecting qubits and enabling logical Clifford operations. However, the number of logical qubits will initially remain limited, posing challenges for resource-intensive tasks like magic state distillation. It is therefore essential to develop efficient methods for implemen...

Recent Advances on Nonadiabatic Geometric Quantum Computation

Zheng-Yuan Xue, Cheng-Yun Ding • Published: 2025-11-10
The geometric phase stands as a foundational concept in quantum physics, revealing deep connections between geometric structures and quantum dynamical evolution. Unlike dynamical phases, geometric phases exhibit intrinsic resilience to certain types of perturbation, making them particularly valuable for quantum information processing, where maintaining coherent quantum operations is essential.

Thomas M. Bickley, Angus Mingare, Tim Weaving, Michael Williams de la Bastida, Shunzhou Wan, Martina Nibbi, Philipp Seitz, Alexis Ralli, Peter J. Love, Minh Chung, Mario Hernández Vera, Laura Schulz, Peter V. Coveney • Published: 2025-05-22
The advent of hybrid computing platforms consisting of quantum processing units integrated with conventional high-performance computing brings new opportunities for algorithm design. By strategically offloading select portions of the workload to classical hardware where tractable, we may broaden the applicability of quantum computation in the near term. In this perspective, we review techniques th...

ReQISC: A Reconfigurable Quantum Computer Microarchitecture and Compiler Co-Design

Zhaohui Yang, Dawei Ding, Qi Ye, Cupjin Huang, Jianxin Chen, Yuan Xie • Published: 2025-11-10
The performance of current quantum hardware is severely limited. While expanding the quantum ISA with high-fidelity, expressive basis gates is a key path forward, it imposes significant gate calibration overhead and complicates compiler optimization. As a result, even though more powerful ISAs have been designed, their use remains largely conceptual rather than practical. To move beyond these hu...

Quanlong Wang, Richard D. P. East, Razin A. Shaikh, Lia Yeh, Boldizsár Poór, Bob Coecke • Published: 2025-11-08
We introduce the Spin-ZX calculus as an elevation of Penrose's diagrams and associated binor calculus to the level of a formal diagrammatic language. The power of doing so is illustrated by the variety of scientific areas we apply it to: permutational quantum computing, quantum machine learning, condensed matter physics, and quantum gravity. Respectively, we analyse permutational computing transit...

Architecting Scalable Trapped Ion Quantum Computers using Surface Codes

Scott Jones, Prakash Murali • Published: 2025-10-27
Trapped ion (TI) qubits are a leading quantum computing platform. Current TI systems have less than 60 qubits, but a modular architecture known as the Quantum Charge-Coupled Device (QCCD) is a promising path to scale up devices. There is a large gap between the error rates of near-term systems ($10^{-3}$ to $10^{-4}$) and the requirements of practical applications (below $10^{-9}$). To bridge this...

Superconducting qubits have motivated the exploration of Josephson-junction technologies beyond quantum computing, with emerging applications in low-energy photon and phonon detection for astrophysics and dark matter searches. Achieving sensitivity at the THz (meV) scale requires materials with smaller superconducting gaps than those of conventional aluminum or niobium-based devices. Here, we repo...

Het 'right to be forgotten' en bijzondere persoonsgegevens: geen ruimte meer voor een belangenafweging? [The 'Right to Be Forgotten' and Sensitive Personal Data: No Room for Balancing?]

Frederik Zuiderveen Borgesius • Published: 2025-11-10
An attorney submitted a 'right to be forgotten' delisting request to Google, regarding a blog post about a criminal conviction of the attorney in another country. The Rotterdam District Court ruled that Google may no longer link to the blog post when people search for the attorney's name. The court granted the attorney's request because the blog post concerns a criminal conviction. Personal data r...

The time qubit

Yakov Bloch • Published: 2025-11-10
A spin precessing in a magnetic field is often used as a quantum clock, for example in tunneling-time measurements. We show that such a clock can exist in a coherent superposition of opposite temporal orientations, treating the arrow of time as a quantum two-level system. A Mach-Zehnder interferometer with equal and opposite magnetic fields provides a simple implementation, enabling interference b...

Saturating the Quantum Cramér--Rao Bound in Prioritised Parameter Estimation

Simon K. Yung, Aritra Das, Jun Suzuki, Ping Koy Lam, Jie Zhao, Lorcán O. Conlon, Syed M. Assad • Published: 2025-11-10
Measurement incompatibility is a cornerstone of quantum mechanics. In the context of estimating multiple parameters of a quantum system, this manifests as a fundamental trade-off between the precisions with which different parameters can be estimated. Often, a parameter can be optimally measured, but at the cost of gaining no information about incompatible parameters. Here, we report that there ar...
