Analog High Performance Computation via High Harmonic Generation: Theoretical Assessment
Abstract
The information technologies are interwoven into many aspects of our lives. They play an ever-increasing role in defense and civil infrastructure. Moore s law characterizing advancements in solid-state microelectronics fuels the progress of the information technologies. However, the dominant paradigm of solid-state digital computers is bound to reach the technological limits with no viable alternative. Thus, it is time to seek novel physical realizations of computing. We propose to initialize a theoretical research program to evaluate the possibility of utilizing extreme nonlinear optical effects as a computational platform. In particular, High Harmonic Generation, a flexible way to produce high order nonlinearities, is proposed to be used for implementing reservoir computing to achieve ultrafast optical information processing. According to the paradigm of reservoir computing, any sufficiently complex system is capable of a universal computation once a suitable linear encoding of input-output data is constructed. Our recent investigations have uncovered that nonlinear optics posses a remarkable flexibility in transforming optical signals, thereby opening the venue for ultrafast reservoir computing. Moreover, HHG opens up the possibility of constructing a full computer based on a single atom or molecule. Arguably, this would be the ultimate limit of miniaturization. This may have important implications for the future of high performance computing, and in particular, may pave the way for the development of petahertz signal processing platforms. We argue that current experimental setups used for High Harmonic Generation Spectroscopy are suited to test our future findings. The proposed work constitutes fundamental research.
