"Breakthrough: Overcoming Quantum Information Transmission Hurdles"
Researchers from the University of Tokyo have developed a new technology for transmitting quantum information over tens to a hundred micrometers, solving a longstanding problem in quantum electronics. By coupling a few electrons in a quantum dot to an electrical circuit known as a terahertz split-ring resonator, they have achieved a coherent interaction suitable for quantum information processing. This breakthrough, based on materials and procedures common in semiconductor manufacturing, could lead to practical implementation and advance the development of large-scale quantum computers.
