  The Superstripes 2016 conference, held on June 23-29, 2016 in the island of
Ischia in Italy celebrated the 20th anniversary of this series of conferences.
For 20 years structural, electronic, and magnetic phase inhomogeneities in
quantum matter have been the scientific focus for a growing physics community
interested in complexity in quantum matter. It has been the meeting point for
different scientific communities facing the challenging project to unveil the
complex space and time landscapes in quantum matter. The interesting spatial
inhomogeneity length scale of multiple coexisting phase ranges from atomic to
mesoscopic and the time fluctuations are spread over multiple time scales. The
response of these materials changes using different experimental techniques
with different spatial and time resolution probing different aspects of the
quantum complexity.
