Homodyne tomography characterization and nonlocality of a dual-mode optical qubit
S. A. Babichev, J. Appel, A. I. Lvovsky
A single photon, delocalized over two optical modes, is characterized by means of quantum homodyne tomography. The reconstructed four-dimensional density matrix extends over the en…

Remote preparation of a single-mode photonic qubit by measuring field quadrature noise
S. A. Babichev, B. Brezger, A. I. Lvovsky
An electromagnetic field quadrature measurement, performed on one of the modes of the nonlocal single-photon state , collapses it into a superposition of the single-…
