Fast coherent control of Rydberg excitations is a key component for quantum logic gates [1] and on-demand single-photon sources based on the Rydberg blockade as demonstrated for room-temperature rubidium atoms in a micro-cell [2]. We pursue an evolution of this single-photon source by employing state-of-the-art 1010 nm fiber amplifiers [3] to drive a Rydberg excitation via the 6P intermediate state. This, together with nanosecond density-switching light-induced atomic desorption (LIAD) pulses, will allow MHz repetition rates and significantly higher photon yields. Here we report on our current observation of GHz Rabi flopping to 32S and 40S Rydberg states. Such excitation timescales also pave the way towards fast optimal control methods for high fidelity Rydberg logic gates.
