    "abstract": "An electromagnetic field quadrature measurement, performed on one of the\nmodes of the nonlocal single-photon state $a|1,0\u003e-b|0,1\u003e$, collapses it into a\nsuperposition of the single-photon and vacuum states in the other mode. We use\nthis effect to implement remote preparation of arbitrary single-mode photonic\nqubits conditioned on observation of a preselected quadrature value. The\nquantum efficiency of the prepared qubit can be higher than that of the initial\nsingle photon.",
