The spin qubit quantum computer is a quantum computer based on controlling the spin of charge carriers (electrons and electron holes) in semiconductor devices. [1] The first spin qubit quantum computer was first proposed by Daniel Loss and David P. DiVincenzo in 1997,.
Quantum engineering uses quantum mechanics as a toolbox for the development of quantum technologies, such as quantum sensors or quantum computers. Many devices that people utilize rely on quantum mechanical effects and have revolutionized the society through medicine, optical communication, high-speed internet, and high-performance computing ...
Computer engineers typically describe a modern computer's operation in terms of classical electrodynamics.Within these "classical" computers, some components (such as semiconductors and random number generators) may rely on quantum behavior, but these components are not isolated from their environment, so any quantum information quickly decoheres.
Superconducting quantum computing is a branch of ... Each qubit is built using semiconductor ... superconducting quantum computing devices must be reliably ...
This list contains quantum processors, also known as quantum processing units (QPUs). Some devices listed below have only been announced at press conferences so far, with no actual demonstrations or scientific publications characterizing the performance. Quantum processors are difficult to compare due to the different architectures and approaches.
Besides confinement in all three dimensions (that is, a quantum dot), other quantum confined semiconductors include: Quantum wires, which confine electrons or holes in two spatial dimensions and allow free propagation in the third. Quantum wells, which confine electrons or holes in one dimension and allow free propagation in two dimensions.
Entirely new approaches for computing exploit the laws of quantum mechanics for novel quantum computers, which enable the use of fast quantum algorithms. The Quantum computer has quantum bit memory space termed "Qubit" for several computations at the same time. In nanoelectronic devices, the qubit is encoded by the quantum state of one or more ...
Important applications of quantum theory include quantum chemistry, quantum optics, quantum computing, superconducting magnets, light-emitting diodes, the optical amplifier and the laser, the transistor and semiconductors such as the microprocessor, medical and research imaging such as magnetic resonance imaging and electron microscopy.
