  • Nobel Prize in Physics 2022: What Are Entangled Photons and Why They Are Important?

    This year’s winners of the Nobel Prize in Physics were announced today, and they are Alain Aspect, John F. Clauser, and Anton Zeilinger for "experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science," as stated by the Nobel Committee. ITMO.NEWS talked to Vladimir Egorov, the head of the university’s Laboratory for Quantum Communications, to learn how these experiments impacted quantum computers and what we should expect next in this field.


  • ITMO Scientists Propose Systems With Unique Interaction Between Photons and Mechanical Motion of Atoms

    The researchers managed to demonstrate that such systems possess the features of non-typical phase transitions, nonstandard symmetry, and its spontaneous breaking in a strong optomechanical interaction regime. This invention may potentially help scientists develop memory chips for future quantum computers.


  • Researchers Demonstrate a Platform for Future Optical Transistors

    Leading research groups in the field of nanophotonics are working toward developing optical transistors –  key components for future optical computers. These devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem for microelectronics engineers. A group of researchers from ITMO University, together with colleagues, have come up with a new solution to this problem by creating a planar system where photons couple to other particles, which enables them to interact with each other. The principle demonstrated in their experiment can provide a platform for developing future optical transistors. The results of their work are published in Light: Science & Applications.
