quantum computing

Researchers have used a quantum computer to simulate particles of matter effectively appearing out of nothing, modelling a phenomenon where virtual particles become real in rapidly changing fields. The demonstration offers a new way to study extreme quantum physics that was previously out of reach of experiments, though detailed findings have not yet been widely reported.

Thales, Bull and the French Alternative Energies and Atomic Energy Commission (CEA) are joining forces to develop software for quantum computers intended for the French armed forces, according to a report by French tech outlet Clubic. The collaboration links a major defence electronics group, a computing company and France's public research body around quantum technology for military use.

Digital certificate authority DigiCert has launched Quantum Central, a new initiative aimed at helping organisations prepare for post-quantum cryptography. The platform is intended to guide businesses through the transition to encryption methods resistant to attacks from future quantum computers. The announcement was reported by The Quantum Insider.

Thales, Bull and the French Alternative Energies and Atomic Energy Commission (CEA) are working together on quantum computing software for the French military, according to a report covered by French tech media. The collaboration ties France's major industrial and research players to defence applications of quantum technology. Commenters are highlighting the strategic significance of quantum computing for national defence and France's push to keep pace in the global quantum race.

Longtime bitcoin critic Peter Schiff says a potential quantum computing hack could push him to short bitcoin entirely, while also suggesting the current market cycle could peak near $600,000. The comments mix his usual skepticism with an unusually high price target, drawing attention from both crypto supporters and critics who see the scenario as far-fetched or contradictory.

Sebastian Hassinger, host of The New Quantum Era podcast, argues that neutral-atom platforms currently hold the lead in the race to scale qubits, citing their combination of high connectivity, long coherence times and rapid experimental progress. His comments add to ongoing debate in the quantum computing community over which hardware approach — superconducting, trapped-ion or neutral atom — will reach practical advantage first.

Researchers have used a quantum computer to simulate how matter can emerge from pure energy, a process linked to pair production in which energetic particles such as photons convert into particle-antiparticle pairs. The demonstration shows how quantum hardware can model fundamental physics processes that are extremely difficult to capture with classical computers, offering a new tool for studying high-energy phenomena.

Claude has reportedly computed a nine-loop scattering amplitude in physics, surpassing a long-standing record associated with Lance Dixon. The result concerns perturbative quantum field theory, where multi-loop amplitude calculations are notoriously difficult. Physicists are discussing whether an AI system genuinely produced a correct result at this complexity level, or whether the claim requires independent verification before it can be accepted by the community.

Security publication BankInfoSecurity is asking whether organizations' networks are prepared for the transition to post-quantum cryptography, the new encryption standards designed to withstand attacks from future quantum computers. The piece underscores growing pressure on enterprises and governments to inventory cryptographic systems and begin migrating before quantum-capable threats materialize.

Anthropic claims its Claude AI model computed a nine-loop particle physics amplitude, an extraordinarily complex calculation in quantum field theory that would normally demand enormous effort from human physicists. If verified, the result would mark a striking demonstration of AI capabilities in theoretical physics, and it is prompting debate among researchers about how the computation was performed and whether it can be independently confirmed.

Quantum computing company IonQ saw its stock rise faster than the overall market, drawing attention from investors tracking the sector. The gain adds to interest in quantum computing names, which have been volatile but closely watched as the technology develops. Traders are weighing whether the momentum reflects genuine business progress or broader speculation around quantum stocks.
