Photon-Coupled, Two-State Photoswitchable Protein-Based Multiple-Valued Logic
Multi-valued logic can be applied in several areas, like robotics and artificial intelligence. It is utilized in various commercial applications, such as the StrataFlash, a NOR flash memory developed by Intel. Contemporary research focuses on the development of fast, nanometer-size, low power consuming electronic devices, therefore it is imperative to examine such concepts in the field of multiple-valued logic. We present a method by which simple, two-state, photon-coupled photoswitchable proteins can be utilized for multiple-valued computations. Its advantages are discussed, and an example, the ternary OR gate, using readily available fluorescent reversibly photoswitchable proteins is provided.
