Session 1: Spin qubits in color centers and dopants

The spin of electrons and nuclei constitutes a highly coherent degree of freedom in the solid state. Color centers and dopants have the additional feature of being, in many ways, the solid-state equivalent of atomic systems. Their simplicity, robustness and exquisite quantum coherence makes them a prime candidate for quantum computing, sensing and communications.

Session 2: Quantum nanophotonics

Single photons can be used to transport quantum information over long distances and therefore play an important role in quantum technology. Recently, important breakthroughs have been made in developing semiconductor-based single-photon sources.

Session 3: Quantum control in molecular qubits

Molecules offer the combination of atomic scale structural control and tunability. Creating and manipulating quantum properties in molecules opens a pathway to designer quantum systems. Results on developing, understanding, and manipulating molecules will be presented.

Session 4: Quantum surface science

Surfaces of materials offer the opportunity to use scanning probe techniques to measure their properties. This can be combined with atomic-scale manipulation to build structures with atomic-scale precision. Recently it has become possible to perform quantum-coherent manipulation of atoms on surfaces.

Session 5: Quantum limits of mechanical motion

Mechanical degrees of freedom in the quantum regime provide new opportunities in sensing, computing, and fundamental tests of quantum mechanics. Via their versatile and strong coupling to many other quantum degrees of freedom (photons, spins, charges) while maintaining high-quality factors, they are now being used to augment quantum devices and test quantum mechanics at large length scales.
