The heralded generation scheme for a 3-GHZ state. Credit: Hui Wang. Photonic quantum computers are computational tools that leverage quantum physics and utilize particles of light (i.e., photons) as units of information processing. These computers could eventually outperform conventional quantum computers in terms of speed, while also transmitting information across longer distances. Despite their promise, photonic quantum computers have not yet reached the desired results, partly due to the inh...
