New Photonic Chip Can able To Robust Quantum Computers

Photonic Chip

In the recent development, scientists have now said to be developed a topological photonic chip. This chip seems to help to process the quantum information that can promise with more robust which is for the robust option for all scalable quantum computes.

This new research was carried out by the research team which was led by RMIT University’s Dr. Alberto Perruzo, who has got it for the very first time. It demonstrated that this quantum information could also be decoded, processed as well as transferred at a distance along with the topological circuits in the chip. This research is said to be published in Science Advances.

This breakthrough can lead to the development of new materials as well as new generation of computers with deep understandings of all types of fundamental science. It is in collaboration with the scientists which is from the Politecnico di Milano and ETH Zurich. The researchers have used the topological photonics which is a rapidly growing field that aims to study the physics of topological phases of matter. It fabricates the chip with a beamsplitter that creates with a high precision photonic quantum gate.

According to Peruzzo, who is the Chief Investigator at the ARC Centre of Excellence for Quantum computation and communication Technology or (CQC2T) and director of Quantum Photonics Laboratory, RMIT said that they have anticipated that this new chip design will be opening the way that will help in studying the quantum effects in the topological materials as well as in a new area of topologically robust quantum processing which is present in the integrated photonics technology. He added by saying that this topological photonics have got the advantage of not requiring the strong magnetic fields as well as it has got the feature intrinsically high in coherence, room-temperature operation, and easy manipulation.

It is said that it is replicating with the well known Hong-Ou-Mandel (HOM) experiment which can take about two photons as well as the ultimate constituents of light as well as it interferes them in as per the laws of the quantum mechanics. The team was now able to use the photonic chip which can demonstrate for the very first time those topological states that can undergo high- fidelity quantum interference.

This research is said to be a part of the Photonic Quantum Processor at CQC2T. It is developed in parallel with the approaching of using the optical and silicon processors which are present in the race to develop the first quantum system.
