The link shows how a `quantum circuit' of the selected design might perform a Hadamard operation followed by a simple CNOT operation with two qubits thus yielding an entangled qubit (or \PMlinkexternal{E.P.R}{http://planetphysics.org/?op=getobj&from=lec&id=119}) pair which is one the four Bell basis states (cf. Brad Rubin, the author of this simulation). Such quantum circuits represent hypothetical possibilites for building a quantum `computer' that would handle qubits of information instead of the regular bits in the existing, Boolean logic computers.
