    "abstract": "We propose a new coherent state quantum key distribution protocol that\neliminates the need to randomly switch between measurement bases. This protocol\nprovides significantly higher secret key rates with increased bandwidths than\nprevious schemes that only make single quadrature measurements. It also offers\nthe further advantage of simplicity compared to all previous protocols which,\nto date, have relied on switching.",
