Abstract: Blind quantum computing is a promising application of distributed quantum systems, in which a client can perform computations on a remote server without revealing any details of the applied circuit. Although the most promising realizations of quantum computers are based on various matter-qubit platforms, implementing blind quantum computing on matter qubits remains a challenge. Using silicon-vacancy (SiV) centers in nanophotonic diamond cavities with an efficient optical interface, we demonstrated a universal quantum gate set consisting of single- and two-qubit blind gates over a distributed two-node network. Using these ingredients, we performed a distributed algorithm with blind operations across our two-node network, proving a route to develop blind quantum computation with matter qubits in distributed, modular architectures. Editor's summary: Quantum computers can outperform classical computers at certain tasks and offer guaranteed security in terms of information communication. However, they are unlikely to be available as individual devices any time soon. Blind quantum computing would allow clients to run their algorithms on quantum servers that are housed in larger facilities without giving away any information about the requested task. Wei et al. demonstrate a small-scale blind quantum computing protocol using optically addressable silicon-vacancy centers. Exploiting the nuclear and electronic spin of the centers for storage and manipulation, the authors demonstrate a set of quantum gates and algorithms across their two-node network. This approach is promising for quantum computing over larger distributed networks. —Ian S. Osborne [ABSTRACT FROM AUTHOR]
