Quantum Brain develops quantum computers, one of the ultimate tools for humanity to understand the universe. In the final chapter of his famous book “Bright Air, Brilliant Fire : On the Matter of the Mind” Gerald Edelman, Nobel Prize winner in Physiology, predicted that brain science and particle physics would meet and ultimately lead humanity to understand the universe. This prediction seems to foreshadow the emergence of quantum computers. In particular, Quantum Brain wants to focus on the development of Qransistor, which minimizes qubit errors by utilizing new topological quantum materials. This will constitute the QPU (Quantum Processing Unit), the core of the quantum computer, and make it possible to create a Topological Quantum Computer, a complete quantum computer.
