Europe Is Sorting Quantum Hardware by Funding Instrument, Not Just Qubit Type

EuroHPC's six August quantum actions continue partnerships selected in 2022. The EU's platform-assessment roadmap is still a draft and is open for public comment.

A universal anyon gate set lands on trapped ions, not topological hardware

Quantinuum's result demonstrates a universal topological gate set on conventional qubits, while the resource advantage that matters remains unproven.

Microsoft Pulled Its Quantum Timeline to 2029. Physicists Are Still Asking Whether It Has Demonstrated the Qubit

Majorana 2 halves Microsoft's timeline to a scalable machine and reports a 20-second parity lifetime. The preprint measured one observable on one nanowire, unreviewed; critics say that is not yet a demonstrated topological qubit.

Majorana Qubits Just Became Readable. Here's Why That Changes the Quantum Computing Race

A team at Delft and CSIC cracked the readout problem for topological qubits - the same architecture Microsoft bet its entire quantum future on.
