Title: Quantum key distribution protocol with pseudorandom bases,
Abstract: Quantum key distribution (QKD) offers a way for establishing
information-theoretically secure communications. An important part of QKD
technology is a high-quality random number generator (RNG) for quantum states
preparation and for post-processing procedures. In the present work, we
consider a novel class of prepare-and-measure QKD protocols, utilizing
additional pseudorandomness in the preparation of quantum states. We study one
of such protocols and analyze its security against the intercept-resend attack.
We demonstrate that, for single-photon sources, the considered protocol gives
better secret key rates than the BB84 and the asymmetric BB84 protocol.
However, the protocol strongly requires single-photon sources.
