... matrices Pi . F () is a sum of convex functions, and P thus convex, so F (x) i pi F (PPi y ). But F () is manifestly permutation invariant, so F (Pi y ) = F (y ), and thus F (x) i pi F (y ) = F (y ), as required. 2. This result can be extended to the domain of operator functionals 6 .

The Effect of Communication Costs in Solid
... by generating an EPR pair. We separate the pair, keeping one qubit, b, at the source and transporting the other, c, to the destination. When we want to send a qubit, a, we first interact a with b using a CNOT gate. We then measure the phase and the amplitude of a, send the two one-bit classica ...

Specifically, we show that Specker’s parable offers a narrative thread that weaves together a large number of results, including: the impossibility of measurement-noncontextual and outcom ...

In order to create squeezed states with arbitrary prescribed value of hJ^z i m0 and arbitrary Dicke states, we propose to use instead the following method: ®rst, a coupling pulse of appropriate strength is applied to the ground state jj; ji, creating an initial CSS with ...
