EurekAlert February 24, 2021 Two years ago, researchers at Princeton University fabricated a new chip designed to improve the performance of neural networks. The chip performed tens to hundreds of times better than other advanced microchips. But the chip’s major drawback was that it uses a very unusual and disruptive architecture as it needs to be reconciled with the massive amount of infrastructure and design methodology that we have and use today. Now the team has created software that would allow the new chips to work with different types of networks, allow the systems to be scalable both in hardware […]

Light, sound, action: Extending the life of acoustic waves on microchips
EurekAlert May 6, 2020 An international team of researchers (Australia, Germany, Denmark) propose to use phonons to store and transfer information that chips receive from fibre-optic cables. They show a way to counteract the intrinsic acoustic decay of the phonons in a waveguide by resonantly reinforcing the acoustic wave via synchronized optical pulses. They experimentally demonstrated coherent on-chip storage in amplitude and phase up to 40 ns, 4 times the intrinsic acoustic lifetime in the waveguide. Through theoretical considerations, they anticipate that this concept allows for storage times up to microseconds within realistic experimental limitations while maintaining a GHz bandwidth […]
