Qubits - Quantum Computing

  1. Dec 9, 2009 #1
    Can someone give me a layman's explanation for the Qubit? And, like the bit, does it represent an intangible, or does it have some material quality to it?

    The bit can have 2 possible values, the qubit can have two plus a superposition of those two values. A qubit represents quantum information and information has no form, though some energy/mass is required to transfer it (eg photon).
