Plastic poses biggest threat to seabirds in New Zealand waters, where more breed than elsewhere

Plastic pollution has the potential to cause the worst damage to seabirds in the seas around Aotearoa New Zealand, where many of them come to feed and breed.

Quantum non-locality in ultra-cold atomic gases

Non-locality, Einstein's ''spooky action at a distance," has been observed between quantum objects separated by more than one kilometer. Recent years have seen a major advancement in the quest for non-local systems. Researchers ...

Future quantum technologies may exploit identical particle entanglement

Usually when physicists perform quantum entanglement between particles—whether it be qubits, atoms, photons, electrons, etc.—the particles are distinguishable in some way. Only recently have physicists demonstrated the ...

How can you tell if a quantum memory is really quantum?

Quantum memories are devices that can store quantum information for a later time, which are usually implemented by storing and re-emitting photons with certain quantum states. But often it's difficult to tell whether a memory ...

Stronger-than-binary correlations experimentally demonstrated for the first time

For the first time, physicists have experimentally demonstrated ternary—rather than binary—quantum correlations between entangled objects. The results show that the quantum measurement process cannot be described as a ...

Quantum simulator offers faster route for prime factorization

Factoring very large numbers into their prime "building blocks" is extremely difficult for classical computers, and this difficulty underlies the security of many cryptographic algorithms. While it's easy to factor the number ...

Generalized Hardy's paradox shows an even stronger conflict between quantum and classical physics

In 1993, physicist Lucien Hardy proposed an experiment showing that there is a small probability (around 6-9%) of observing a particle and its antiparticle interacting with each other without annihilating—something that ...

Real-world intercontinental quantum communications enabled by the Micius satellite

A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). ...
