In the past 4 years the COST Action MP1403 Nanoscale Quantum Optics (NQO) established and supported crosslinks between quantum science & technology, nanoscale optics & photonics and materials science. The Action has recently released a Roadmap on Research and Innovation in NQO and the associated Market Research Study. The full reports and the executive summaries are available for download at www.cost-nqo.eu/support/documents/. Feedback is welcome and can be submitted to cost-nqo@uni-siegen.de
