Entanglement in a qubit-qubit-tardigrade system

Quantum and biological systems are seldom discussed together as they seemingly demand opposing conditions. Life is complex, "hot wet" whereas quantum objects small, cold well controlled. Here, we overcome this barrier with a tardigrade -- microscopic multicellular organism known to tolerate extreme physiochemical conditions via latent state of life cryptobiosis. We observe coupling between the animal in cryptobiosis superconducting bit prepare highly entangled combined system another qubit. The itself shown be remaining subsystems. then observed return its active form after 420 hours at sub 10 mK temperatures pressure $6\times 10^{-6}$ mbar, setting new record for that complex can survive.
