New 4D quantum sensors may help physicists trace the birth of space and time

Physicists are developing new 4D quantum sensors called SMSPDs to improve particle detection in high-energy colliders. These sensors can track both the spatial and time coordinates of particles with exceptional precision, outperforming conventional detectors. The technology could help identify lower-mass particles and potentially detect dark matter. As particle accelerators become more powerful, these advanced detectors may play a crucial role in future experiments, offering scientists a more detailed view of subatomic collisions and the fundamental nature of the universe.
