TOKYO, Japan - Hitachi High-Technologies Corp. has produced a micro diamond ring (in handout photo), which can only be seen under microscope and is believed to be the world's smallest, by utilizing technology normally used to produce semiconductors. The ring, with a 0.02 millimeter diameter, bears a five billionth of a carat diamond. It was created by Yasushi Kuroda, an employee of the company's subsidiary Hitachi Science Systems Ltd., to illustrate that the company's equipment can be used to make micro machines. (Kyodo)

                NEC's vector-based simulated annealing machine

                NEC is making a full-scale entry into the quantum computing domain. From April to June 2020, the company will launch a co-creation service to solve combinatorial optimization problems, including the use of annealing machines that employ the SX Aurora Tsubasa vector supercomputer. Prior to this, the company will establish a new 20-person Quantum Computing Promotion Office in January 2008 to promote the development of applications and technologies through joint demonstrations with customers. The company plans to invest about 1 billion yen in Canada's D-Wave Systems for collaboration. On the other hand, the quantum annealing system will be based on a domestically developed machine jointly developed with the National Institute of Advanced Industrial Science and Technology (AIST) and D-wave, which will be a collaborative partner. The joint development with AIST is currently verifying the operation of a basic quantum cell. Photo taken on December 20, 2019, credit: Nikkan Kogyo Shimbun / Kyodo News Images
