It is widely accepted that consciousness or, more generally, mental activity is in some click correlated to the behavior of the material brain. Since quantum theory is the most fundamental theory of matter that is currently available, it is a legitimate question to ask whether quantum theory can help us to understand consciousness. Several approaches answering this question affirmatively, proposed in recent decades, will be surveyed. There are three basic types of corresponding approaches: 1 consciousness is a manifestation of quantum processes in the brain, 2 quantum concepts are used to understand consciousness without referring to brain activity, and 3 matter and consciousness are regarded as dual aspects of one underlying reality.

1. Introduction

Major contemporary variants of these quantum-inspired approaches will be discussed. It will be pointed out that they make different epistemological assumptions and use quantum theory in different ways. For each of the approaches discussed, both problematic and promising features will be highlighted. The problem of how mind and matter are related to each other has many facets, and it can be approached from many different starting points. The historically leading disciplines in this respect are philosophy and psychology, which were later joined by behavioral science, cognitive science and neuroscience.

In addition, the physics of complex systems and quantum physics have played stimulating roles in the discussion from their beginnings. As regards the issue of complexity, this is evident: the brain is one of the most complex systems we know. The study of neural networks, their relation to the operation of single neurons and other important topics do and will profit a lot from complex systems approaches. As regards quantum physics, there can be no reasonable doubt that quantum events occur and are efficacious in the brain as elsewhere in the material world—including biological systems.

The original motivation in the early 20th century for relating quantum theory to consciousness was essentially philosophical. On the other hand, randomness is problematic for goal-directed volition! Quantum theory introduced an element of randomness standing out against the previous deterministic worldview preceding it, in which randomness expresses our ignorance of a more detailed description as in statistical mechanics. In sharp contrast to such epistemic randomness, quantum randomness in processes such as the spontaneous emission of light, radioactive decay, or other examples has been considered a fundamental feature of nature, independent of our ignorance or knowledge.

To be precise, TThe feature refers to individual https://amazonia.fiocruz.br/scdp/blog/work-experience-programme/ethics-of-the-workplace-business-application.php events, whereas the behavior of ensembles of such events is statistically determined. The indeterminism of individual quantum events is constrained by statistical laws. Other features of quantum theory, which became attractive in discussing issues of consciousness, were the concepts of complementarity and entanglement.]
