A group of physicists recently placed a microscopic animal known as a tardigrade onto a superconducting qubit, in an attempt to mingle the realms of quantum and classical mechanics. The researchers argue that the tardigrade was entangled at a quantum level, but some scientists say the team’s claims go beyond what they actually achieved.

The results aren’t published in a journal but are currently hosted on the preprint server arXiv.
