    "abstract": "The random switching of measurement bases is commonly assumed to be a\nnecessary step of quantum key distribution protocols. In this paper we show\nthat switching is not required for coherent state continuous variable quantum\nkey distribution. We show this via the no-switching protocol which results in\nhigher information rates and a simpler experimental setup. We propose an\noptimal eavesdropping attack against this protocol, for individual Gaussian\nattacks, and we investigate and compare the no-switching protocol applied to\nthe original BB84 scheme.",
