Three particle Hyper Entanglement: Teleportation and Quantum Key
... We describe a system of particles in such a way that one particle is entangled to all other particles in different degrees of freedom. Let us consider a system consisting of three photons where photon 2 is entangled with photons 1 and 3 in different degrees of freedom namely OAM and polarization res ...

Transformations of Entangled Mixed States of Two Qubits
... It is easily seen that if |ψi i is an N-dimensional column vector then the density matrix is N × N matrix because of the matrix multiplication of column vector |ψi i from the right with a row vector hψi | . Note that n is the number of elements in E = {pi , |ψi i} and there is no obvious relation be ...

... applications. In this paper, we consider the suppression of the phase decoherence in an atomic qubit, which is composed of a single neutral atom confined in a far-detuned optical dipole trap. The qubit is defined by two hyperfine states of the atom. This system is an excellent candidate for quantum ...

... Therefore P2 = I and the parity operator is unitary. If the interaction Hamiltonian (H) conserves parity then [H,P]=0, and: PY(x, y, z) = Y(-x, -y, -z) = nY(x, y, z) with n = eigenvalue of P P2Y(x, y, z) = PPY(x, y, z) = nPY(x, y, z) = n2Y(x, y, z) Y(x, y, z) = n2Y(x, y, z) n2 = 1 so, n=1 or n=-1 ...

In this respect, the assumption of finite precision of all physically realizable state preparation, manipulation, and registration procedures is particularly important, and can even be treated as an empirical given. This premise is general enough to subsume (a) fundamental limitations imposed by the ...
