Guha Discusses "The New Information Currency"

This year's Nobel Prize in Physics was awarded to a team of European and American researchers who study quantum entanglement, which holds profound implications in computing and data encryption. According to the International Society for Optics and Photonics, the Royal Swedish Academy of Sciences awarded the Physics prize to the trio of researchers “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.” 

ECE professor and Director of the Center for Quantum Networks Saikat Guha said entanglement among “distant parties” will be “the new information currency for the quantum information era.”

“Prof. Zeilinger, one of the Laureates, demonstrated teleportation of the state of single qubits, and also showed how shared entanglement can be turned into shared secret keys which would enable secure communications whose security promises derive from the laws of quantum physics being true,” he said. “Entanglement shared across global scales will enable quantum computers to work together to solve complex problems that are inaccessible with today’s supercomputers."
