Over the past two decades, the fields of quantum information theory and quantum technology have emerged and matured.
The state-of-the-art theoretical and experimental tools developed in this context make it possible to revisit the very foundations of quantum theory and explore the Terra Incognita that may lie beyond. In this Insight we survey recent trends in the study of the foundations of quantum mechanics: from expanding or even rethinking quantum theory, to ambitious new experiments that will seek the elusive effects of quantum gravity.
The Insight will be available FREE online to registered nature.com users until 1 May 2014.
