New chip offers way to make use of quantum system 'imperfections'

Phys · · 586 words · By KTH Royal Institute

Researchers at KTH Royal Institute of Technology have developed a photonic chip that simulates how quantum systems lose energy and information to their surroundings. The device allows scientists to study 'imperfections' in a controlled environment to determine if they can be utilized as resources for future quantum technologies.
