Manipulating transverse modes of photons for quantum cryptography
Several schemes have been proposed to extend quantum key distribution protocols aimed at improving their security or at providing new physical substrates for qubit implementation. We present a toolbox to jointly create, manipulate, and measure qubits stored in polarization and transverse-modes degre...
