Many physicists are searching for a triplet superconductor. Indeed, we could all do with one, although we may not know it yet ...

Scientists have finally figured out how to read ultra-secure Majorana qubits—bringing robust quantum computing a big step closer. “This is a crucial advance,” says Ramón Aguado, a CSIC researcher at ...

Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the ...

Can quantum become even bigger than AI? And will it help soften the AI bubble as it seems set to burst? Experts share their views.

Quantum computing has long occupied the edges of our collective imagination – frequently mentioned, rarely understood. For many, it remains a distant prospect rather than an immediate concern. But ...

The people who know IonQ, Rigetti, and D-Wave best are sending an unmistakable signal to investors.

Rigetti stock has been wildly volatile, surging as much as 270% in 2025 to a high of $56 per share before crashing back down ...

If you are to believe the glossy marketing campaigns about ‘quantum computing’, then we are on the cusp of a computing ...

Cisco inserted itself into a quantum networking trial with Qunnect that integrated the former’s enterprise-grade ...

Analysts say quantum computing concerns may be weighing on Bitcoin’s valuation versus gold, raising long-term questions.

A CoinShares report finds that quantum computing risk to Bitcoin remains distant, with less than 0.1% of BTC potentially exposed.

New research says today’s quantum computers are far too weak to threaten Bitcoin’s cryptography, leaving the network years to ...
