Quantum software startup Algorithmiq raised 18 million euros co-led by CDP Venture Capital and United Ventures, relocated its global headquarters to Milan, and pushed total funding to 36 million euros in what investors call Italy's largest quantum VC round.

Powell and Buchalter show in Physical Review B that periodically switched magnetic fluxes through a Harper-Hofstadter lattice can produce topological phases that no equilibrium material can host.

A 120-qubit simulation finished in two minutes versus more than 100 hours classically, with the team also reporting direct observation of spin-charge separation on 62 qubits.

London-based Quantum Motion has raised $160 million in Series C funding co-led by DCVC and Kembara to commercialize silicon-CMOS quantum processors that the company says fit in three standard server racks.

A University of Oxford group has experimentally demonstrated quadsqueezing, a fourth-order quantum interaction long thought too weak to observe, by harnessing non-commutativity between two laser-driven forces on a single trapped ion.

Researchers from the Wellcome Sanger Institute and University of Oxford encoded the Hepatitis D virus genome onto IBM's 156-qubit Heron processor, marking the first time a complete genome has been processed on quantum hardware.

A quantum-inspired tensor network method achieves exponential speedup on topological quasicrystals, opening a feedback loop between quantum materials and quantum computer design.

DARPA's Heterogeneous Architectures for Quantum program will fund 19 teams over 24 months to combine different qubit types into unified quantum systems, abandoning the single-technology approach.

Paris-based C12 published a four-stage plan to scale its carbon nanotube spin-qubit processors from 16 physical qubits in 2027 to over 100,000 by 2033, betting a solid-state modality can catch incumbents on error-corrected quantum computing.

IonQ linked two trapped-ion quantum systems via photonic entanglement in a first for commercial quantum computing, and won a DARPA contract to extend the approach across multiple qubit types.

Nvidia's new Ising family targets quantum error correction and calibration, claiming 2.5x faster and 3x more accurate decoding than the current open-source standard, with more than 20 labs and hardware makers already on board.

Rigetti Computing has made its 108-qubit Cepheus-1-108Q system generally available through its own cloud platform and Amazon Braket, marking the first gate-based quantum processor exceeding 100 qubits on AWS.
