Researchers at NIST and the University of Maryland have developed a new method for “quantum data buffering” that could revolutionize quantum computing. The technique involves creating pairs of multi-pixel quantum images, where each pixel in one image is perfectly correlated with the corresponding pixel in the other image, even when they are physically separated.
The team demonstrated that they could delay the arrival time of one of the entangled images by up to 27 nanoseconds using a gas cell to slow down the light beam. This “delayed entanglement” has been previously demonstrated with individual photons, but never with information-rich quantum images.
The potential impact of this research is significant, as it could enable more efficient control of data flow in future quantum computers. The ability to buffer and delay quantum data could be crucial for developing quantum communication systems and quantum information processing technologies.
