One crucial building block are\r\ntailored nanoscale integratable quantum light sources, matching the specific\r\nneeds of use-cases. Several different approaches to realize solid-state quantum\r\nemitters [2] with high performance [3] have been pursued. However, the\r\nproperties of the emitted single photons are always defined by the individual\r\nquantum light source and despite numerous quantum emitter tuning\r\ntechniques [4-7], scalability is still a major challenge. Here we show an\r\nemitter-independent method to tailor and control the properties of the single\r\nphoton emission. We demonstrate a laser-controlled down-conversion process from\r\nan excited state of a quantum three-level system [8]. Starting from a biexciton\r\nstate, a tunable control laser field defines a virtual state in a stimulated\r\nprocess. From there, spontaneous emission to the ground state leads to\r\noptically controlled single photon emission. Based on this concept, we\r\ndemonstrate energy tuning of the single photon emission with a control laser\r\nfield. The nature of the involved quantum states furthermore provides a unique\r\nbasis for the future control of polarization and bandwidth, as predicted by\r\ntheory [9,10]. Our demonstration marks an important step towards tailored\r\nsingle photon emission from a photonic quantum system based on quantum optical\r\nprinciples.","lang":"eng"}],"ddc":["530"]}
