“This paper represents a breakthrough in the simulation of physical systems which are otherwise essentially impossible,” Kosterlitz said in a D-Wave news release. “The test reproduces most of the expected results, which is a remarkable achievement.”
Chinese researchers report that they’ve set a new distance record for quantum teleportation through space, the phenomenon that Albert Einstein once scoffed at as “spooky action at a distance.”
The technology isn’t yet ready for prime time, but eventually it could open the way for a new type of unbreakable encryption scheme based on the weirdness of quantum physics.
The experiment, reported today in the journal Science, involved transmitting pairs of entangled photons from China’s orbiting Micius satellite to ground stations in the mountains of the Tibetan plateau, separated by more than 745 miles (1,200 kilometers).
Purdue University says it has signed a five-year agreement with Microsoft to expand its role in an international quantum computing collaboration known as Station Q.
Microsoft announced last November that it was moving ahead with its Station Q campaign to build a working computer. The consortium now extends to Purdue as well as TU Delft in the Netherlands, the Niels Bohr Institute in Denmark, the University of Sydney in Australia, ETH Zurich in Switzerland and the University of Maryland.
Purdue has been working with Microsoft on quantum computing for more than a year, but the newly signed agreement deepens the connections at Station Q Purdue.
Microsoft says it’s moving ahead from just talking about quantum computing to building an actual quantum computer, based on the physics that won a Nobel Prize this year.
The project will be headed by longtime Microsoft executive Todd Holmdahl, who previously played key roles in developing the Xbox gaming console, the Kinect motion sensor and the HoloLens augmented-reality system. Now he’s corporate vice president of Microsoft’s quantum program.
“I think we’re at an inflection point in which we are ready to go from research to engineering,” Holmdahl said in a Microsoft blog posting about the project on Nov. 20.
Microsoft isn’t alone in the field: For several years, Google has been working with NASA and a Vancouver-area company called D-Wave to evaluate quantum computer designs.
