Research Breakthrough Takes Supercomputing Out of the Lab

University of Toronto (04/30/12)

University of Toronto researchers have developed a system that they say will make the production of a special class of photons used in supercomputing faster and easier.  In order for advanced technologies, such as ultra-secure communication systems and optical quantum computers, to work a photon must be tightly coupled with another photon.  The Toronto researchers have designed a new integrated system that could produce the entangled photon pairs using an integrated circuit, which could lead to the production of photons using a single chip.  “The research offers the prospect of unleashing the potential of the powerful and underutilized quantum technologies into the main stream commercial world, out of the lab,” says Toronto professor Amr Helmy.  The researchers say that utilizing quantum optical computing will be important in solving difficult computational problems, such as complex data sorting.
