. Proposals range from quantum mind theories (for an overview see Atmanspacher \cite{sep-qt-consciousness}) to consciousness of classical machines \cite{Dehaene_2017} to mention only a few. 
The now following proposal departs clearly from ideas in quantum mind theories which are mostly based on von Neumann's measurement process derived from the Copenhagen’s interpretation (A survey under physicists in revealed that). It is also not a quantum field theory based on Umezawa ideas in the 1960s \cite{Ricciardi_1967}. Most importantly, it opposes, as the quantum mind theory of Penrose \cite{penrose1989emperor} did,  the idea that the mind could be based on classical computation. 
Instead, we propose that the brain is a quantum computer which can experience consciousness; a quantum computer that processes information in quantum bits (qubits) using quantum gates. At a first glance, it seems unrealistic or impossible that the brain can meet the challenges to provide both. Nevertheless, we will provide a rough roadmap to show that the brain may have the incredible ability to perform quantum computing in the following way. First, we will unveil the existence of an unknown non-neuronal computing network in the brain. Then, we will further argue that this network must be based on quantum computing. Finally, we sketch how that could be realized.
