Prototype Could be Used to Connect Quantum Computers

Facebook X LinkedIn Email
Physicists from the Institute of Science and Technology Austria (IST Austria) used a mechanical oscillator to produce entangled radiation. According to the research team, this is the first time a mechanical object has been used to create entangled radiation. Beyond its significance for fundamental physics, such a device could someday be used to link sensitive quantum computers with the optical fibers that connect computer networks. Classical computers are typically connected through optical fibers, because optical radiation is robust against disturbances that could corrupt or destroy...Read full article

    quantum
    The term quantum refers to the fundamental unit or discrete amount of a physical quantity involved in interactions at the atomic and subatomic scales. It originates from quantum theory, a branch of physics that emerged in the early 20th century to explain phenomena observed on very small scales, where classical physics fails to provide accurate explanations. In the context of quantum theory, several key concepts are associated with the term quantum: Quantum mechanics: This is the branch of...
    quantum entanglement
    Quantum entanglement is a phenomenon in quantum mechanics where two or more particles become correlated to such an extent that the state of one particle instantly influences the state of the other(s), regardless of the distance separating them. This means that the properties of each particle, such as position, momentum, spin, or polarization, are interdependent in a way that classical physics cannot explain. When particles become entangled, their individual quantum states become inseparable,...
