Luminous (US based company backed by Bill Gates) it trying to build chips that use light to move data and carry out calculations.
Being the spin of an electron in a qubit, or the wavelength of a photon in a "waveguide", the future of chips is going to be in the realm of quantum computing.
Moore's law is dead, long live Moore's law! :D
...widely used electrical chips like central processing units aren’t ideal ... because they use a lot of power and may not be able to process data fast enough. The bottleneck is getting worse: a study by research institute OpenAI says the amount of computing power needed to train the largest AI models is doubling every three and a half months. Luminous... uses lasers to beam light through tiny structures on its chip, known as waveguides. By using different colors of light to move multiple pieces of data through waveguides at the same time, it can outstrip the data-carrying capabilities of conventional electrical chips.
