Query: Enhancing quantum cryptography with quantum dot single-photon sources   Quantum cryptography harnesses quantum light, in particular single photons,
to provide security guarantees that cannot be reached by classical means. For
each cryptographic task, the security feature of interest is directly related
to the photons' non-classical properties. Quantum dot-based single-photon
sources are remarkable candidates, as they can in principle emit
deterministically, with high brightness and low multiphoton contribution. Here,
we show that these sources provide additional security benefits, thanks to the
tunability of coherence in the emitted photon-number states. Generating either
mixed or coherent states of light allows for enhanced performance of many
quantum cryptography applications. We identify the optimal optical pumping
scheme for the main quantum-cryptographic primitives, and benchmark their
performance with respect to Poisson-distributed sources such as attenuated
laser states and down-conversion sources. The presented results will guide
future developments in solid-state and quantum information science for photon
sources that are tailored to quantum communication tasks.
