| Abstract: |
A method and apparatus are disclosed for controlling the quantum state probability distribution of one quantum object of a pair of correlated quantum objects, which include providing a pair of correlated quantum objects, each of said objects having a uniform quantum state probability distribution, providing a system for controlling the quantum state probability distribution of the one quantum object by using said controlling system to choose the probability distribution of the observable quantum states of the other quantum object of the pair of correlated quantum objects, using said controlling system to choose the probability distribution of the quantum states of the other quantum particle, choosing whether to observe the quantum state of the other quantum object, and subsequently observing the quantum state of the one quantum object of said pair of correlated quantum objects to determine if said prepared quantum state probability distribution of said one quantum object has been altered by an observation of the quantum state of the other quantum object. By such method and apparatus, information may be selectively transmitted on observation of the quantum state of the one quantum object by selectively controlling the quantum state probability distribution of the other quantum object of the pair of correlated quantum objects.

What is claimed:
1. A method for controlling the quantum state probability distribution of a plurality of correlated pairs of quantum objects which pairs have entangled spin states, comprising the steps of:
- a. providing a plurality of entangled pairs of quantum objects, each pair including one quantum object and an other quantum object, said pairs existing in a superposition of spin states in at least one chosen spin basis;
- b. providing a means for transforming said entangled pairs of quantum objects into a definite spin state in a chosen spin basis;
- c. providing means for controlling the spin state probability distribution of the one quantum objects which is capable of choosing the spin state probability distribution of the corresponding other quantum objects of the pairs of entangled quantum objects in a chosen spin basis;
- d. choosing whether to change the spin state probability distribution of the other quantum objects of the pairs of entangled quantum objects using said controlling means;
- e. choosing whether to observe the spin state probability distribution of the other quantum objects of the pairs of quantum objects in a chosen spin basis using said controlling means;
- f. subsequently observing the spin state probability distribution of the one quantum objects of said entangled pairs of quantum objects in a chosen spin basis to determine if said spin state probability distribution of said one quantum objects of said pairs of quantum objects has been altered by an observation of the spin state probability distribution of said other quantum objects of said pairs.
