Quantum computers where a figment of science fiction imagination it seems, until just a few years ago. Now it seems like every month there is a new breakthrough in quantum computer science and real prototypes are being built and tested. Here is the latest.
Dr. Beena Kalisky, from Bar-Ilan University’s Department of Physics and Institute for Nanotechnology and Advanced Materials, together with researchers from France, Italy, the Netherlands, Spain and Sweden, is developing Quantum Technology using 2D interfaces created between oxides as part of the QUANTOX project (QUANtum Technologies with 2D-Oxides).
The research is financed by QuantERA, a European Research Fund that brings together 31 research funding agencies from 26 countries, and coordinated by the National Science Centre in Poland and the Israel Innovation Authority.
Developing a quantum computer is one of the most desirable objectives today, and research in the field is supported by such companies as Microsoft, Bell Labs, IBM and Google. Quantum computation will have a major effect on computer performance and information security. Developing such a computer first requires the development of a basic memory cell, Qubit, using technology which is topologically protected. Despite the immense technological challenge, the advantage of such computers in speedy calculations and noise resistance has led to significant investment in research and development in the field.
The development process is both challenging and complex. In this project the challenge is especially significant due to the technological difficulty of measuring phenomena based on minute electrical currents in substances with a 2D flow. The lab headed by Dr. Kalisky develops highly sensitive sensors for measuring magnetic fields, and uses them to map tiny magnetic fields that are generated by a small number of electrons, or very weak electrical currents. The measurement is conducted in Dr. Kalisky’s lab, in a local and non-invasive fashion, allowing feedback for the development process even before reaching the complex stages of connecting a memory cell to the entire system, and so enabling the development to be focused and accelerated.
Dr. Kalisky commented:
The highly sensitive magnetic imaging tool which we operate in the lab is very helpful for development stages, especially in fields of research conducted at cold temperatures. Exciting quantum physics takes place at temperatures close to the absolute 0 and we are excited to harness our research tools to these major objectives.
The agreement between the parties was carried out by Birad – Research & Development Company Ltd. the commercializing company of Bar-Ilan University.
