The archerfish is one of Southeast Asia’s deadliest sharpshooters. When a tasty insect or spider catches its eye on the banks of a mangrove forest, the small, striped swimmer fires a precise, high-powered jet of water from its mouth, knocking the bug into the river, where it can be gobbled up.

Physicists Claim They’ve Quantum Entangled a Tardigrade With a Qubit. But Have They?

by

A team of physicists claims to have entangled a superconducting qubit and a tardigrade, moving the freezing, tiny, and well-controlled world of quantum into the “hot and wet” systems of life.   However, the results described in this preprint paper are not quite so cut and dried, and many quantum researchers are arguing that the … Read more
