- 1Programmable fusion method scales up photonic quantum states▼Deterministic and programmable fusion for the scalable generation of photonic graph states
Researchers report a deterministic and programmable fusion technique for generating photonic graph states at scale, published in Nature. Graph states are entangled networks of photons that underpin photonic quantum computing and quantum networking. The advance suggests fusion operations can be controlled on demand rather than relying on probabilistic outcomes, a key hurdle to building large optical quantum systems.

A ranking of the most persistent myths in physics is drawing wide attention, covering popular misconceptions such as the idea that nothing can travel faster than light or that quantum entanglement allows faster-than-light communication. The piece walks through each claim and explains what the science actually says, prompting discussion among science fans about which myths are most widely believed.
- 3Scientists crack 25-year quantum entanglement challenge▼Quantum teleportation breakthrough: Scientists crack a 25-year entanglement challenge
Researchers report a breakthrough in quantum teleportation, solving a problem in entanglement that has stood for 25 years. The advance could strengthen quantum communication and computing research, though the specific team, method and institution behind the result are not detailed in available coverage. Details of the experiment and its practical implications remain limited at this stage.
