We demonstrate the strong coupling between a single electron spin in silicon and a single photon in a superconducting microwave cavity. Using the same cavity we perform rapid high-fidelity single-shot readout of two-electron spin states.

Parametric downconversion sources often trade generation rate for increased purity. We present a feed-forward scheme that mitigates the adverse effects of filtering on photon generation rates while simultaneously removing uncorrelated noise from the source output.

Full characterization of quantum system is both necessary and overwhelming task as complexity grows. In our letter we propose a simple experimental scheme based on compressed sensing to characterize close to pure many-level quantum systems with reasonable accuracy. Our technique could efficiently characterize quantum sources, channels and systems.

In contrast to standard communication, counterfactual communication (CFC) counterintuitively allows information exchange without particle exchange. In this paper we use advances in integrated photonics to implement a CFC protocol that does not rely on post-selection.
