KRISS designs world’s 1st niobium-based superconducting nano-device

The Republic of Korea’s exclusive government-funded measurement laboratory, KRISS has reportedly announced developing the world’s first ever niobium-based nano-device which can be deployed in a quantum computer.

For the record, a quantum computer generates information by quantum computing unlike the binary computers of today. In fact, it is able of swiftly handling tasks that are unresolvable with these using a quantum mechanical phenomenon.

Reports suggest that although both aluminum and niobium boast of superconducting properties, the latter, in particular, is being extensively studied as a superconducting nano-device. This attributes to niobium’s resistance to environmental factors.

As per official report, the distance between a substrate electrode and the nano-device, in order to create a string electrodynamic interaction, has to be maintained at 100nm or more. Although this is not easy owing to the residual stress, the institute improved niobium deposition on the substrate and successfully developed the niobium superconducting nano-device, creating a ground-breaking model for the quantum computers.

It would be important to note that the device has been brought to the real world post two years of exhaustive research by KRISS scientists. Importantly, the device can be used at 269.15 degree Celsius below zero and an external magnetic field of 0.8T.

According to KRISS, these conditions are superior to operating environments of the current aluminum devices with 272.15 degree Celsius below zero with an external mag. field of 0.01T.

While speaking on the novel development, a source close to the institute mentioned that the team of scientists have been planning the development of an optical signal converter for distant quantum data device connection with niobium-based nano-device.

It was further added that the novel technology will be usable for quantum computer devices, high-precision spin detection, and much more; in the upcoming years.
