Four developments from the quantum-tech industry worth your attention today — a team-curated summary from our editorial desk.
Alice & Bob Publishes a Detailed Estimate for Running Shor’s Algorithm on Cat Qubits
Alice & Bob researchers posted an end-to-end resource estimate for Shor’s algorithm on superconducting cat qubits to the IACR Cryptology ePrint Archive. Under stated assumptions — a 1 µs error-correction cycle, a 10 µs reaction time and no bit-flip errors — factoring RSA-2048 would need about 23,000 cat qubits and 3.14 days; solving the elliptic-curve discrete-logarithm problem on secp256k1 would need at most 30,000 cat qubits and about an hour. Trading space for time, RSA-2048 would run in 1.25 hours on roughly 611,000 cat qubits, and relaxing the no-bit-flip assumption with an extra error-correcting layer raises the figure to about 45,000. This is a paper-based estimate on hardware that does not yet exist at that scale, and the preprint has not been peer reviewed.

EU Joint Research Centre: 12.9% of Quantum Technology Signals Are Already Operational
The Joint Research Centre (JRC), the science service of the European Commission, published its Outlook Report on Quantum Technologies, which analyses 195 foresight signals drawn from the scientific literature. Nearly half are still at proof-of-concept stage, almost a third have reached system-demonstration level, and 12.9% are already operational — quantum random number generators being one commercial example. The authors identify potential in twelve thematic areas, expect most sectors to be users rather than builders of quantum technology, and warn against waiting for full commercial maturity before preparing. The report also notes that the EU hosts almost a third of the world’s quantum technology companies and that an EU Quantum Act is planned for 2026.

Pasqal’s 256-Qubit Processor Finds an Unexpected Slowdown in a 2D Quantum Magnet
Pasqal and partners at the Flatiron Institute, the University of Augsburg, Forschungszentrum Jülich, the University of Regensburg and Institut d’Optique Graduate School / CNRS used a 16×16 array of 256 rubidium atoms to study how a two-dimensional transverse-field Ising magnet relaxes after a sudden quench. Besides rapid thermalization and a prethermal regime, they report a crossover regime in which relaxation slows down — precisely where state-of-the-art classical tensor-network methods lose control at late times, while the quantum simulation stays consistent across system sizes. It is a physics observation rather than a demonstration of practical advantage, and the work is a preprint on arXiv that has not yet been independently confirmed.

D-Wave and LG CNS Sign MOU on Enterprise Quantum Optimization
D-Wave and South Korean IT services firm LG CNS signed a non-binding memorandum of understanding at D-Wave’s Qubits Asia conference in Seoul. The companies plan to combine D-Wave’s quantum annealing with LG CNS’s mathematical-optimization and systems-integration expertise for customers in manufacturing, telecommunications, finance and retail, with use cases such as factory scheduling, delivery routing and resource allocation. The stated aim is to move projects from proof of concept into production and to pursue joint go-to-market opportunities; as the agreement is non-binding, no commercial terms were disclosed.
