- 1Quantum memory stores single photons for record time▼Quantum memory stores single photons for record time in major leap towards a quantum internet
Researchers report a quantum memory that has stored single photons for a record length of time, a result described as a major step towards building a quantum internet. Long-lived storage of individual light particles is a key requirement for quantum repeaters, the devices needed to send entangled signals across continental distances. The achievement is drawing attention as a milestone in quantum communication research.

Physicists have reportedly achieved a measurement of the lesser-known 'other' kind of quantum entanglement, a milestone 25 years in the making. The advance could deepen understanding of quantum correlations beyond the standard spin-based type, with implications for quantum information research. The claim is circulating among physics and science enthusiasts online.

Physicists have, after 25 years of effort, developed a way to measure the 'other' kind of quantum entanglement, a form distinct from the widely studied entanglement used in quantum computing and cryptography. The achievement gives researchers a practical tool for detecting and quantifying this rarer correlation between quantum systems, opening new avenues for experiments in fundamental physics.

Physicists have successfully measured the W state of three quantum-entangled photons, a specific type of multi-particle entanglement where entanglement is shared unevenly among the photons. The achievement, reported by ScienceAlert, demonstrates refined experimental control over complex quantum states, a capability relevant to quantum computing, quantum communication and fundamental tests of quantum mechanics. Science observers are sharing the result as a notable step in entanglement research.

The 1935 Einstein-Podolsky-Rosen paradox argued that quantum mechanics was incomplete. In 1964, John Bell showed the question could be tested experimentally. Experiments between 1972 and 2015, including a Delft test measuring entangled electron spins 1.3 kilometres apart, found correlations that no local hidden variable theory can explain, settling the debate in favour of quantum mechanics.

Researchers report that quantum entanglement present in the vacuum disappears when exposed to sufficiently strong external fields. The finding suggests that strong fields can strip away the correlations that normally link vacuum modes, with potential implications for quantum field theory and how physicists model field-matter interactions. The result is drawing attention among physics readers curious about its theoretical consequences and whether it could be tested experimentally in the near future.

Physicists report achieving quantum entanglement between a levitating nanoparticle of glass and light without the extreme cooling usually required, working at room temperature. The result is a notable step for quantum physics, since entangling solid objects with light typically demands cryogenic conditions, and it could advance research into quantum sensing and the limits of quantum behaviour in larger objects.

Researchers publishing in Nature report a deterministic and programmable fusion technique for generating photonic graph states at scale. Photonic graph states are entangled light states central to photonic quantum computing, networking and repeaters. Making fusion deterministic rather than probabilistic, while keeping it programmable, is presented as a step toward scalable quantum photonics. The finding matters because scaling entangled photon sources has been a key bottleneck for optical quantum technologies.

Researchers in Innsbruck, Austria, are building a prototype quantum internet, work that aims to connect quantum computers and enable ultra-secure communication based on entanglement. The project marks an early step toward networks that could, in principle, transmit information with security guarantees impossible for today's internet. Details beyond the announcement are limited so far.
- 15Study Suggests Quantum Entanglement May Come From Hidden Dimension●Quantum Entanglement May Emerge From a Hidden Extra Dimension, New Study Suggests
A new study proposes that quantum entanglement, the phenomenon linking particles regardless of distance, could emerge from an extra hidden dimension rather than being a fundamental feature of spacetime. The suggestion revives long-standing questions about how entanglement works and whether spacetime itself is built from deeper structures. Physicists are likely to debate the idea, as any proposal tying entanglement to extra dimensions touches both quantum theory and attempts to unify physics.
