A team of scientists have recently developed a topological photonic chip in order to process the quantum information, which is promising a comparatively more robust option for the scalable quantum computers. The research team that is being led by the RMIT University’s Dr. Albert Peruzzo have for the first time demonstrated that the quantum information, which can be coded, processed, and transferred at a particular distance with the topological circuits on the photonic chip. This research study has been recently published in the Science Advances.
This breakthrough is expected to lead to the development of several new materials, deeper understandings of fundamental science, and new generation computers. After the collaboration with the team of scientist from the ETH Zurich and Politencio di Milano, the resaerchers made use of the topological photonics, which a rapidly developing field that aims to study and understand the physics of topological phases of matter in a novel optical context so as to fabricate a chip along with a beamsplitter forming a high precision quantum gate.
Dr. Albert Peruzzo, the Chief Investigator at the ARC Centre of Excellence for Quantum Computation and Communication Technology and Director of the Quantum Photonics Laboratory, RMIT stated that they anticipate that the new chip design is expected to open the way the way for studying the quantum effects in the topological materials and to a new field of topologically robust quantum processing in the integrated photonics technology.
Furthermore, the topological photonics have the advantage of not demanding a strong magnetic fields and feature the intrinsically high-coherence, easy manipulation, and room-temperature operation. In addition to this, these are essential requirements for the scaling up of the quantum computers. The team of researchers were further able to make use of the photonic chip so as to demonstrate that the topological states can under high-fidelity quantum interference.
