IBM Research | One photon to switch them all: An ultra-efficient optical switch that could link quantum computers @ibmresearch | Uploaded September 2021 | Updated October 2024, 4 days ago.
IBM researchers and collaborators have managed to build an ultrafast, ultra-efficient all-optical switch that takes only a few photons to switch. This device could allow hundreds of times faster switching than the fastest commercial transistors available today. And it does so while consuming nearly the rock-bottom limit in terms of power consumption. Which means: Your future gadgets could be much faster and your battery would last much longer!
