Removing exactly one photon from an arbitrary input pulse is an elementaryoperation in quantum optics and enables applications in quantum informationprocessing and quantum simulation. Here we demonstrate a deterministicsingle-photon absorber based on the saturation of an optically thick free-spacemedium by a single photon due to Rydberg blockade. Single-photon subtractionadds a new component to the Rydberg quantum optics toolbox, which alreadycontains photonic logic building-blocks such as single-photon sources,switches, transistors, and conditional $\pi$-phase shifts. Our approach isscalable to multiple cascaded absorbers, essential for preparation ofnon-classical light states for quantum information and metrology applications,and, in combination with the single-photon transistor, high-fidelitynumber-resolved photon detection.
