... epistemological principle, namely that an objective phenomenon is only defined relative to an observation. In this the notion of "observation" brings with it the notion of "an observer"; concerning this, Bohr held that the observer must be described in terms of classical concepts. I shall call the c ...

... (with pseudo-eigenvalue 1) and linearly independent (but not orthogonal) set {|1i−|ki : k = 2, . . . , d} (with (d−1)degenerate pseudo-eigenvalue -1). Making the direct sum of these eigenvectors gives us a pseudo-eigensystem of U , with pseudo-eigenvalues ±1. There are many other choices of the refl ...

... of clauses, the problem is whether there exists a truth assignment of all the x's to make O satis able. To evaluate the truth value of O for a given assignment of the literals is easy and it can be carried out in polynomial time. However it is dicult to check if a Boolean set O is satis able or not ...

Rule 1 (State Description) N states, probability vector Rule 2 (Evolution) N x N stochastic matrix Rule 3 (Measurement) A measurement with k outcomes is described by k N dimensional real vectors with positive components. If we sum over all of these k vectors then we obtain the all 1’s vector. If our ...

While the photonic platform for quantum information processing has much in its favor, it suffers from imperfect detector efficiency and photon loss which gets worse as the number of optical components is scaled up. It is not under ...
