Photon Detected, But Not Absorbed

Facebook X LinkedIn Email
It's possible to detect something as fragile as a single photon without destroying it, new research suggests. Single-photon sources have important applications in quantum networking, cryptography and information processing. While there are several methods capable of detecting single light particles, none are very efficient, and most destroy (use all the photon's energy) the particle in the detection process. But Andreas Reiserer and colleagues at the Max Planck Institute of Quantum Optics have developed a device that leaves the photon untouched upon detection. Conceptual...Read full article

    photon
    A quantum of electromagnetic energy of a single mode; i.e., a single wavelength, direction and polarization. As a unit of energy, each photon equals hn, h being Planck's constant and n, the frequency of the propagating electromagnetic wave. The momentum of the photon in the direction of propagation is hn/c, c being the speed of light.
