The usual argument against is that physicists have to work hard to produce entanglement in the carefully controlled conditions that exist in the lab.

Their main point is that biological systems are thermodynamic open driven systems which are far from equilibrium. &#8220;In such systems error correction can occur which may maintain entanglement despite high levels of decoherence,&#8221; they say.<\/p>\n<p>That&#8217;s a good point.
