Applied to medium- sized biomolecules with and without hydration shells, the technology could, in the future, uncover effects of solvation on structure, conformation, and photo- induced conformation changes. Quantum interferometry with complex nano - particles is still vast uncharted territory. Thousands of quantum objects, dozens of particle properties, and many new manipulation techniques remain to be explored. Often those quantities are intrinsically more dynamic in complex, warm molecules than they would be in static atoms. Ongoing high-mass interference experiments at the University of Vienna allow handling of de Broglie wavelengths as small as 200 fm. Taking that as the current standard, a source that delivers nanoparticles of 106 atomic mass units (1.66 × 10−24 g) at a velocity of 1 m/s would be suitable for interferometry exper￾iments. Various new sources are being developed to prepare tailor- made molecules and nanoparticles of 107 amu or more for interferometry experiments. Quantum interferometry with biological nano￾materials is a fascinating short-term goal. Quantum physics with proteins or DNA having masses in the range 10 000−100 000 amu would open a new field of research and technology at the interface between quantum optics, physical chemistry, and biomolec￾ular physics. The goal is challenging but not beyond reach: With the successful quantum interference last year of functionalized organic molecules composed of 810 atoms (see figure 5), matter-wave interferom￾etry has already crossed the 10 000-amu threshold.15 I am grateful for support from my research group and from the European Research Council, the European Commission, the Austrian Science Fund, and the University of Vienna.
