    "abstract": "We present an analysis of quantum-limited DPSK receivers with optical\nMach-Zehnder interferometer (MZI) demodulation. It is shown for the first time\nthat the quantum limits for DPSK/MZI receivers with single-port and balanced\ndetections exactly differ from 3-dB in receiver sensitivity, obtained by both\nPoisson and Gaussian noise statistics.",
