   [2]Can entanglement exist in biological systems?

   Posted: 09 Jul 2008 12:48 AM CDT

   [3]Bioentanglement 

   Can entanglement exist in biological systems? The usual argument
   against is that physicists have to work hard to produce entanglement
   in the carefully controlled conditions that exist in the lab. So it's
   hardly likely that entanglement will ever be found in systems that are
   warm, wet and messy, like human bodies for instance.

   But Sandu Popescu from the University of Bristol in the UK and Hans
   Briegel from the University of Innsbruk in Austria do a convincing job
   today of arguing otherwise. Their main point is that biological
   systems are thermodynamic open driven systems which are far from
   equilibrium. "In such systems error correction can occur which may
   maintain entanglement despite high levels of decoherence," they say.

   That's a good point. But it is better made later in their paper when
   they point out that we already know entanglement can exist in open
   driven systems at room temperature.

   "[This] is absolutely clear, once one realizes that every quantum
   physics laboratory is such a system."

   Nicely put! The paper is by no means a proof that biological systems
   exploit entanglement but it certainly challenges the naysayers to
   think more carefully about their case.
