Quantum circuits for OR and AND of ORs
We give the first quantum circuit for computing f( 0)OR f( 1)more reliably than is classically possible with a single evaluation of the function. OR therefore joins XOR (i.e. parity, f( 0)f( 1)) toExpand

Quantum probability from decision theory?
In a recent paper, Deutsch claims to derive the ‘probabilistic predictions of quantum theory’ from the ‘non–probabilistic axioms of quantum theory’ and the ‘nonprobabilistic part of classicalExpand
