As reported by the editorial Board Phys.org, an international group of researchers has taken a big step toward creating an optical quantum computer, with its enormous research potential in various fields: from the creation of new drugs to simulate the behavior of individual molecules. This was achieved through the development of optical microchip to generate, control and detect a certain state of light, called a compressed vacuum.
The creation of the device is a large team of scientists from all over the world, including Griffith University in Queensland, University of münster in Germany, the Australian national University, University of New South Wales in Canberra and the Centre for quantum computation and communication technology.
“What we have demonstrated with our device is an important technological step towards creating an optical quantum computer to solve certain problems much faster than any modern car.” — said the researchers.
The microchip has a length of 1.5 cm, width 5 cm and thickness 0.5 cm, and inside components are installed that interact with the light beam. These components are connected by small channels and waveguides that guide the light around the chip. In this approach, the formed interconnected network of electric circuit.
“In addition to the possibility of creating new drugs and materials, optical quantum computation will improve energy-saving methods, and to perform ultra-fast search in the database. They will also help to solve complex mathematical problems.”
According to the researchers, their experiment is a first step towards creating an optical quantum computer. This path includes 3 phases: generation of quantum States of light (what have you accomplished scholar), the manipulation of States and their rapid reconfiguration.
