Kazimir Malevich’s Tochil’schik Printsip Mel’kaniia, or The Knifegrinder (1912–13), exemplifies the fragmentation of forms characteristic of futurism and echoes the superposition of states characteristic of quantum mechanics. On page 36 , Tim Langen describes dipolar supersolids, a class of quantum materials that are simultaneously solid and superfluid. On page 44 , Peter Lodahl, Arne Ludwig, and Richard Warburton describe how advances in quantum materials are leading to new applications in quantum computation.
