The knowledge and technologies invented and accumulated in the field of quantum information science are turning into near-future industrial technologies and products. The most obvious example is the quantum computer, in which many IT giants started investing large sums to develop. Besides the quantum computer, 'quantum technologies' also includes sensing and communication. Dr Yuimaru Kubo is an expert on quantum information science and technologies with 'spins in gem crystals'. He is based at the Okinawa Institute of Science and Technology (OIST) where his research team is currently investigating how quantum information can be stored, transmitted, or amplified with unprecedented efficiencies utilising the spins of electrons or nuclei in 'gem crystals'.
