Is there a functional role for quantum mechanics or coherent quantum effects in biological processes? While this question is as old as quantum theory, only recently have measurements on biological systems on ultra-fast time-scales shed light on a possible answer. In this review we give an overview of the two main candidates for biological systems which may harness such functional quantum effects: photosynthesis and magnetoreception. We discuss some of the latest evidence both for and against…

The Emergence of Mind as a Quantum Field Phenomenon
TLDR
This paper hypothesizes that the construct of the mind is the resultant of chaotic system of interacting subatomic fields driven by force fields that intersperse with the quantum vacuum; a mechanism which has not yet been fully understood.

Nitric oxide sensing by chlorophyll a
TLDR
A simple but straightforward way for sensing different NO species using chlorophyll, the source of inspiration being hemoglobin that serves as a NO sink in most mamalian system and the predicted binding affinity matching with the experimental observation is revealed.

Tinkering with the Unbearable Lightness of Being: Meditation, Mind-Body Medicine and Placebo in the Quantum Biology Age
TLDR
There are empirical indications that mind-body therapies have a nonlocal quantum component, in addition to the psychoneuroimmunological pathways that have been the focus of the predominant experimental paradigm, and the case is made that there should be a convergence of research agendas between mind- body interventions, photomedicine and quantum biology.

Quantum effects in biology
Theoretical examination of quantum coherence in a photosynthetic system at physiological temperature
TLDR
The numerical results reveal that quantum wave-like motion persists for several hundred femtoseconds even at physiological temperature, and suggest that the FMO complex may work as a rectifier for unidirectional energy flow from the peripheral light-harvesting antenna to the reaction center complex by taking advantage of quantum coherence and the energy landscape of pigments tuned by the protein scaffold.
Quantum coherence and its interplay with protein environments in photosynthetic electronic energy transfer.
TLDR
An overview of recent experimental and theoretical investigations of photosynthetic electronic energy transfer paying particular attention to the underlying mechanisms of long-lived quantum coherence and its non-Markovian interplay with the protein environment is provided.
Environment-assisted quantum walks in photosynthetic energy transfer.
TLDR
A theoretical framework for studying the role of quantum interference effects in energy transfer dynamics of molecular arrays interacting with a thermal bath within the Lindblad formalism is developed and an effective interplay between the free Hamiltonian evolution and the thermal fluctuations in the environment is demonstrated.

TLDR
It is demonstrated that quantum coherence effects play a big role in light energy transport in photosynthetic green sulfur bacteria under physiological conditions, thereby significantly increasing the efficiency of the energy capture process, presumably helping the bacteria to survive in low light.
Limits of quantum speedup in photosynthetic light harvesting
It has been suggested that excitation transport in photosynthetic light-harvesting complexes features speedups analogous to those found in quantum algorithms. Here we compare the dynamics in these…
Direct evidence of quantum transport in photosynthetic light-harvesting complexes
TLDR
Experimental evidence is provided that interaction between the bacteriochlorophyll chromophores and the protein environment surrounding them not only prolongs quantum coherence, but also spawns reversible, oscillatory energy transfer among excited states.

Long-lived quantum coherence in photosynthetic complexes at physiological temperature
TLDR
Evidence that quantum coherence survives in FMO at physiological temperature for at least 300 fs, long enough to impact biological energy transport is presented, proving that the wave-like energy transfer process discovered at 77 K is directly relevant to biological function.
