This is an interesting topic but the basic idea is due to the quantum superposition. Recently it was realized that macroscopic systems (computers are also macroscopic devices) will obey a nonlinear Schrodinger equation (see for instance arXiv:0711.1442 attached bellow). Hence, the superposition principle is no more valid.Attachment #1: 0711.1442.pdf

    "How much information is really there in a quantum state?"

    And how does one go about counting or accounting it?

    How far back into the past does a Quantum State remain intact, what memory of a previous state does a Q-bit have/retain?

    To possibly be in "Two Places at Once", one really has to define "place" , what here is meant place?..is this the same as being in "two space's" at one instant of time?..so thus a particle can be in ANY two location of the future, or ANY two locations of a past, but curiously NEVER in a single location of the present/now?

    To be at two seperated locations "in a superposition", one has to be isolated from the "time" that governs both loctions, thus external to a 4-Dimensional space-time.

    Has there been a single recorded example of an Electron being detected in a single place, ie a definate "now"?

    Already Rafael Bombelli (1526-1573) understood that any complex number occurs together with its conjugate (suo Residuo), cf. Helmut Gericke, Geschichte des Zahlbegriffs. Accordingly, a complex representation of a real world quantity is redundant. It does not convey more information as compared with the seemingly poorer real-valued one. I will reconsider this as soon as the first quantum computer shows its claimed superiority.
