Scattering model for quantum random walk on the hypercube
... (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 ...

Four-photon orbital angular momentum entanglement
... Twin photons that are created by SPDC are correlated in several degrees of freedom and exhibit quantum entanglement. Apart from the well-known polarization degrees, the photons can also be correlated in their spatial degrees; this manifests itself in continuous wavevector or (the Fourier-related) po ...

If we use photons with p = h/ to measure the momentum of an object, p, p of the object cannot be less than ~h/ since the photon changes the momentum of the object upon scattering.
