-
For example, in both systems, when an electron at the lowest possible energy level is excited (by a photon or another particle), the resulting interaction between the electron and the hole left behind cannot be described as a quasiparticle (as it can in ordinary metals), because the electron excitation decays so quickly.

In the process of this screening, both types of electrons actually clump together to form a composite object, or quasiparticle, which is very heavy.

Also, a full proof of the irrelevance of quasiparticle-mediated quantum effects in room temperature organic systems would also require a proof that quasiparticles cannot be used to construct qubits, or at least that any qubits constructed in such a fashion cannot then be linked back to the classical components of the system.

In each experimental run, the elevated quasiparticle densities caused the wavelike entities to overlap and form condensates, the investigators say.
-
In short: To complete the assertion that room temperature systems cannot include quantum behaviors, a rigorous analysis of the quasiparticle issue is required.

I suspect that if molecular non-classical data transfers and quasiparticle condensates exist, such components could also be configured to build qubits.

I suppose one could propose that quantum-capable quasiparticle waves exist within tubulins, but why in the world would one bother?

In the condensate, the bosonic quasiparticle pairs are coupled to each other and can be described by a macroscopic wave function with a well defined phase.
