Quantum Measurement Theory
... let us choose 0.5 < α < 1. With this choice, if x = 0 then it is more likely that we will get the result y = 0, and if x = 1 it is more likely that we will get y = 1. Now assume that we initially know nothing about x, so that our prior state of knowledge is P (0) = 0.5 = P (1). What happens when we ...

Lower bounds for quantum communication complexity

The above notion of weakly unbounded error protocols coincides with another type of protocol, namely majority nondeterministic protocols, which accept an input, whenever there are more nondeterministic computations leading to acceptance than to rejection. For a proof see theorem 10 in [20]. So weakl ...
