- 1CEA-Leti and Quobly Deepen Partnership on Silicon Quantum TechnologiesโผCEA-Leti and Quobly Strengthen Their Collaboration to Accelerate the Development of Next-Generation Silicon Quantum Technologies
French research institute CEA-Leti and quantum computing startup Quobly have announced an expanded collaboration aimed at accelerating the development of next-generation silicon-based quantum technologies. The partnership builds on their existing work and focuses on advancing silicon qubit technology as a route toward scalable quantum computing. Details of the agreement, including financial terms and specific milestones, have not been disclosed in initial reports.
- 2Neutral atoms lead the quantum qubit race, says HassingerโผSebastian Hassinger (The New Quantum Era): why neutral atoms lead the qubit race for now
Sebastian Hassinger, host of The New Quantum Era podcast, argues that neutral-atom platforms currently hold the lead among quantum computing qubit technologies. He points to the approach's combination of scalability, long coherence times and flexible connectivity as reasons it is outpacing rival architectures such as superconducting and trapped-ion systems, at least for now.
- 3Bitcoin Quantum Attack Estimate Cut to 1,151 QubitsโผBitcoin Quantum Attack Cost Halved to 1,151 Qubits [2026]
New analysis suggests the qubit count needed to break Bitcoin's cryptography has been halved to around 1,151 logical qubits, based on improved estimates published for 2026. The finding revives debate over how soon quantum computers could threaten Bitcoin wallets and whether the network should accelerate a migration to quantum-resistant cryptography, a topic developers and researchers have discussed for years.
- 4Microsoft opens Majorana quantum chips to DARPA testingโผMicrosoft opens Majorana quantum chips to DARPA for independent testing
Microsoft has offered its Majorana-based quantum chips to DARPA for independent evaluation, a move that would subject the company's contested topological qubit claims to outside scrutiny. The announcement drew attention in semiconductor and quantum computing circles, where experts have debated whether Microsoft's Majorana approach represents a genuine breakthrough or an unproven path. Independent testing by the US defense agency could lend credibility to, or undermine, the technology.
- 5New Quantum Codes Tolerate Qubit Loss and GainโQuantum Codes Correct Errors Even With Qubit Loss Or Gain
Researchers have described quantum error-correcting codes that keep working even when the number of qubits in a system changes, rather than remaining fixed. The approach corrects errors despite qubit loss or gain, addressing a practical weakness in quantum computing hardware where components are routinely lost or degraded. If confirmed and implemented, such codes could make quantum computers more robust and bring reliable, large-scale quantum computation closer to reality.
- 6New quantum chip uses quasiparticles to link distant qubitsโผNew quantum chip taps into weird quasiparticles to get qubits to communicate over long distances
Researchers have unveiled a quantum chip that uses exotic quasiparticles to enable qubits to communicate over long distances, a persistent challenge in quantum computing since qubits typically interact only at very short ranges. The approach could help scale up quantum processors by allowing information to move reliably between distant parts of a machine, though details of the team's results and practical performance have not yet been widely reported.
- 7New qubit could cut quantum computing errors by 100 timesโผThis new qubit could be 100 times less error-prone in superfluid quantum computer breakthrough
Researchers report the development of a new type of qubit that could be around 100 times less error-prone than existing designs, using superfluid technology. Error rates are one of the biggest obstacles to building practical quantum computers, so any significant reduction is seen as a meaningful step toward more reliable, scalable quantum machines.
