Core Viewpoint - MicroCloud Hologram Inc. has proposed an innovative high-dimensional quantum key distribution (QKD) protocol that utilizes quantum Fourier transform, enhancing security and information efficiency in quantum transmission [1][5]. Group 1: Quantum Key Distribution Protocol - The proposed QKD protocol employs a coding framework that ensures secure key distribution through quantum operations, specifically quantum Fourier transform and quantum-controlled NOT gate [1][2]. - The secret information is concealed within the relative phases of high-dimensional entangled states, allowing for secure storage and retrieval of information [2][3]. - High-dimensional quantum states significantly increase information-carrying capacity compared to traditional binary states, breaking the previous limit of 1 bit per particle [3][4]. Group 2: Security and Performance - The QKD protocol demonstrates superior cryptographic performance, surpassing traditional methods that rely on mathematical problems, thus reducing the risk of compromise as computational power increases [4]. - The protocol is based on quantum mechanics principles, such as the no-cloning theorem and Heisenberg's uncertainty principle, which fundamentally prevent information eavesdropping or tampering [4][5]. - The high-dimensional quantum state key allows for the transmission of more keys under the same conditions, addressing the growing demands for information security in the big data era [4][5]. Group 3: Future Implications - The advancements made by MicroCloud in the QKD protocol lay a solid foundation for the future development of quantum key distribution technology, potentially leading the field into a new stage of development [5].
