Quantum bits (qubits) hold promise for the realization of quantum computers, which will surpass classical computers for specific tasks, such as searching large databases or performing quantum chemical computations. Moving forward, materials optimization will be instrumental to improve the performance and scalability of qubits and enable the realization of practical quantum computers. In this focus issue, our collection of articles explores the materials-related challenges and opportunities for different types of qubits, including superconducting, trapped-ion, spin, germanium and topological qubits. See Qubits meet materials science.

Nanomaterials can be engineered to exploit different nano–bio interactions with a single system. Such multifunctionality is particularly important for the treatment of complex and heterogeneous diseases, such as cancer. Biomolecule-based nanostructures, including polysaccharides, nucleic acids, peptides and proteins, are often intrinsically bioactive as targeting and/or therapeutic agents, making them ideal building blocks for the design of smart cancer nanomedicines. See Wang, J. et al.
