Terahertz Frequency Pulses Uncover Hidden State of Matter

Facebook X LinkedIn Email
Researchers have used ultrafast photonics to visualize electrons interacting as a hidden state of matter in a superconductive alloy. When fully understood and tuned, this state of matter could be used for faster, heat-free quantum computing, information storage, and communication. The new approach is a quantum switching scheme, developed by researchers at Iowa State University and Ames Laboratory, called terahertz-light quantum tuning. It uses photon pulses of trillionths of a second at terahertz frequency to selectively bombard (without heating) superconducting Nb3Sn (niobium-tin),...Read full article

    terahertz
    Terahertz (THz) refers to a unit of frequency in the electromagnetic spectrum, denoting waves with frequencies between 0.1 and 10 terahertz. One terahertz is equivalent to one trillion hertz, or cycles per second. The terahertz frequency range falls between the microwave and infrared regions of the electromagnetic spectrum. Key points about terahertz include: Frequency range: The terahertz range spans from approximately 0.1 terahertz (100 gigahertz) to 10 terahertz. This corresponds to...
    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...
