DESCRIPTION:Quantum and biological systems are seldom discussed together a
 s they seemingly demand opposing conditions. Life is complex\, "hot and we
 t" whereas quantum objects are small\, cold\, and well controlled. We can 
 overcome this barrier with an organism able to tolerate the stringent cond
 itions that quantum experiments operate in. One such candidate is the tard
 igrade\,  a microscopic multicellular organism known to tolerate extreme p
 hysicochemical conditions via a latent state of life known as cryptobiosis
 . By positioning a tardigrade in cryptobiosis near a superconducting quant
 um bit\, we observe coupling between the animal and the qubit. In addition
 \, a highly entangled state between this combined system and another qubit
  was prepared\, with the tardigrade shown to be entangled with the remaini
 ng subsystems via electric field coupling. The animal is then observed to 
 return to its active form after 420 hours at sub 10 mK temperatures and pr
 essures below 6 X 10^{-6} mbar\, setting a record for the conditions that 
 a complex form of life can survive.
