Scalable Quantum Light Source Enables Quantum Cryptography, Computing

Facebook X LinkedIn Email
Researchers at Stevens Institute of Technology and Columbia University have developed a scalable, precise method for creating large numbers of quantum light sources on a chip. These light sources could be used for quantum computers and quantum cryptographic systems. The researchers said that the method combines spatial control and scalability with the ability to efficiently emit photons on demand. Researchers have created a scalable platform for on-chip quantum emitters. Courtesy of Stevens Institute of Technology. The researchers used the corners of a metal nanocube for both...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...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    nanoplasmonics
    Nanoplasmonics is a branch of nanophotonics that focuses on the study and manipulation of optical phenomena at the nanoscale using plasmonic materials and structures. Plasmonics deals with the interaction between electromagnetic radiation and free electrons in metals or other conductive materials, leading to the formation of surface plasmons—collective oscillations of electrons at the metal-dielectric interface. Nanoplasmonics explores how these surface plasmons can be harnessed and...
