Time-Bin Encoding Technique Enables High-Rate QKD for Cybersecurity

Facebook X LinkedIn Email
Researchers have developed a quantum key distribution (QKD) system that enables a greater number of secret bits to be packed into a single photon. The new technique allows for two secret bits in a single photon, with a secret key rate of 26.2 megabits per second. Current QKD systems are only able to transmit 10,000 to 100,000 secret bits per second. QKD, an emerging quantum technology that enables the establishment of secret keys between two or more parties in an untrusted network, is widely regarded as a viable solution to the security threats posed by future quantum computers....Read full article

    quantum optics
    The area of optics in which quantum theory is used to describe light in discrete units or "quanta" of energy known as photons. First observed by Albert Einstein's photoelectric effect, this particle description of light is the foundation for describing the transfer of energy (i.e. absorption and emission) in light matter interaction.
    quantum key distribution
    Quantum key distribution (QKD) is a method of secure communication that utilizes principles from quantum mechanics to establish a shared secret key between two parties, typically referred to as Alice and Bob, while detecting any potential eavesdropping attempts by a third party, commonly known as Eve. The fundamental principle behind QKD is the use of quantum properties, such as the superposition principle and the no-cloning theorem, to enable the distribution of cryptographic keys in a...
