Quantum 10, 2007 (2026). https://doi.org/10.22331/q-2026-02-23-2007 We study the task of localizing multipartite entanglement in pure quantum states onto a subsystem by measuring the remaining systems. To this end, we fix a multipartite entanglement measure and […]
Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers have worked to rigorously demonstrate such advantages, ideally in ways […]
Quantum 10, 2006 (2026). https://doi.org/10.22331/q-2026-02-23-2006 We propose modifying topological quantum error correcting codes by incorporating space-time defects, termed “time vortices,” to reduce the number of physical qubits required to achieve a desired logical error rate. […]
Insider Brief IQM Quantum Computers has agreed to merge with Real Asset Acquisition Corp. in a SPAC transaction that would take the superconducting quantum computing company public in the United States at a pre-money equity […]
Quantum 10, 2005 (2026). https://doi.org/10.22331/q-2026-02-23-2005 In stochastic modeling, the excess entropy – the mutual information shared between a process’s past and future – represents the fundamental lower bound of the memory needed to simulate its […]
Insider Brief Australia’s Critical Technologies Challenge Program (CTCP) is providing stage 2 funding to quantum-related projects as part of a broader $36 million grant initiative supporting solutions to national challenges. Eight round 1 stage 1 […]
Insider Brief Tectonic Labs has launched PQ Wallet, a post-quantum-ready EVM wallet extension supporting Falcon-512 signatures, alongside PQ Audits to help teams assess quantum risk and plan NIST-aligned migrations. PQ Wallet operates at the application […]
Insider Brief Technology Innovation Institute (TII) has launched a cloud service providing partners with access to its in-house superconducting quantum processing units (QPUs). The QPUs, developed by TII’s Quantum Computing Hardware Lab, range from 5 […]
Insider Brief Quantum computing encompasses multiple hardware approaches built on different physical foundations, and the field can be understood along two practical dimensions: system reliability and physical architecture. Most current systems operate in the NISQ […]
Insider Brief An Italian administrative court has suspended Campania’s €61 million euro contract to install a quantum computing system at the University of Salerno, delaying the region’s planned “quantum valley.” The court accepted an appeal […]
