The quantum mind or quantum consciousness is a protoscientific hypothesis that posits a connection between consciousness, neurobiology, and quantum mechanics. There are many blank areas in understanding the dynamics of the Human brain and especially how it gives rise to consciousness. The hypothesis claims that quantum mechanics is capable of explaining conscious experience.

Introduction

---

The nature of consciousness and its place in the universe remain unknown. Classical models view consciousness as computation among the brain's neurons but as yet have failed to describe an exact mechanism. Quantum processes in the brain have been invoked as explanations for consciousness and its enigmatic features. Some theories have been subjected to experimental tests, and evidence that indicates quantum non-locality occurs in conscious and subconscious brain functions has been claimed; however, these results have not gained wide acceptance.

Supporters argue that the brain can no longer be seen as simply a vast piece of organic clockwork, but rather as a subtle device amplifying quantum events; that quantum computation would surely be advantageous from an evolutionary perspective; and that biology has had four billion years to solve the decoherence problem and evolve quantum mechanisms.

Adiabatically switched-on electrical bias and the Landauer--B[u-umlaut]ttiker formula
H. D. Cornean, P. Duclos, G. Nenciu, and R. Purice Consider a three dimensional system which looks like a cross connected pipe system, i.e., a small sample coupled to a finite number of leads. We investigate the current running through this system, in the linear response regime, when we adiabatically turn on an electrical bias between leads. The mai ... [J. Math.

Lower spectral branches of a spin-boson model
Nicolae Angelescu, Robert A. Minlos, Jean Ruiz, and Valentin A. Zagrebnov We study the structure of the spectrum of a two-level quantum system weakly coupled to a boson field (spin-boson model). Our analysis allows to avoid the cutoff in the number of bosons, if their spectrum is bounded below by a positive constant. We show that, for small coupling constant, the lower pa ... [J. Math.

The structure of degradable quantum channels
Toby S. Cubitt, Mary Beth Ruskai, and Graeme Smith Degradable quantum channels are among the only channels whose quantum and private classical capacities are known. As such, determining the structure of these channels is a pressing open question in quantum information theory. We give a comprehensive review of what is currently known about the struct ... [J.
