Dr. Matthew P.A. Fisher will give a public lecture as part of the 80th Birthday celebration of Nobel Prize Winner and Macarthur Professor of Physics, Anthony Leggett. Reception following the talk at the I Hotel.
Speaker: Matthew P.A. Fisher (Univ of California, Santa Barbara). Professor Fisher received his PhD from Illinois.
Title: Are we quantum computers, or merely clever robots?
About the Talk
Of course quantum information processing is not possible in the warm wet brain. There is, however, one "loophole" - offered by nuclear spins - that must be closed before acknowledging that we are merely clever robots. Putative neural quantum processing with nuclear spins seemingly requires fulfillment of many unrealizable conditions: for example, a common biological element with a very isolated nuclear spin to serve as a qubit, a mechanism for quantum entangling qubits, a mechanism for quantum memory storage and processing, a quantum to biochemical transduction that modulates neuron firing rates, among others. My strategy, guided by these requirements, is one of reverse engineering seeking to identify the bio-chemical substrate and mechanisms hosting such putative quantum processing. Remarkably, a specifc neural qubit and a unique collection of ions, molecules and enzymes is identifed, illuminating an apparently single path towards nuclear spin quantum processing in the brain.
