CEA-Leti Announces a Fundamental Breakthrough in Fabricating Quantum Bits

Facebook X LinkedIn Email
CEA-Leti, a French technology research institute of the French Alternative Energies and Atomic Energy Commission (CEA) and the Institute for Nanoscience and Cryogenics (Inac) fundamental research institute, has announced a breakthrough towards large-scale fabrication of quantum bits, or qubits, the building blocks of future quantum processors. CEA-Leti demonstrated a new level of isotopic purification in a film deposited by chemical vapor deposition on a 300-mm preindustrial platform, enabling the creation of qubits in thin layers of silicon using 28Si, a high-purity silicon isotope,...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.
