    en.wikipedia.org/wiki/Physical_and_logical_qubits

    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 ...

    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.

    The ones indicate bits in the address used for the network prefix and the trailing block of zeros designates that part as being the host identifier. The following example shows the separation of the network prefix and the host identifier from an address (192.0.2.130) and its associated / 24 subnet mask (255.255.255.0). The operation is ...
