A physical qubit is a physical device that behaves as a two-state quantum system, used as a component of a computer system. [ 1 ] [ 2 ] A logical qubit is a physical or abstract qubit that performs as specified in a quantum algorithm or quantum circuit [ 3 ] subject to unitary transformations , has a long enough coherence time to be usable by ...
The general definition of a qubit as the quantum state of a two-level quantum system.In quantum computing, a qubit (/ ˈ k juː b ɪ t /) or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device.
Yoshihisa Yamamoto and K. Igeta propose the first physical realization of a quantum computer, including Feynman's CNOT gate. [17] Their approach uses atoms and photons and is the progenitor of modern quantum computing and networking protocols using photons to transmit qubits and atoms to perform two-qubit operations.

Pictures and films created using computers. Usually, the term refers to computer-generated image data created with the help of specialized graphical hardware and software. It is a vast and recently developed area of computer science. computer network. Also data network. A digital telecommunications network which allows nodes to share resources.
In August 2022, Baidu released its plans to build a fully integrated top to bottom quantum computer which incorporated superconducting qubits. This computer will be all encompassing with hardware, software and applications fully integrated. This is a first in the world of quantum computing and will lead to ground-breaking advancements. [60]
