Quantum teleportation moves the quantum state of a system between physical locations without losing its coherence, an essential criterion for emerging quantum information applications. Now, electron-spin-state teleportation in covalent organic electron donor–acceptor–stable radical molecules is demonstrated using entangled electron spins produced by photo-induced electron transfer.

Frequency-bin qubits get the best of time-bin and dual-rail encodings, but require external modulators and pulse shapers to build arbitrary states. Here, instead, the authors work directly on-chip by controlling the interference of biphoton amplitudes generated in multiple, coherently-pumped ring resonators.

It is generally assumed that no-signalling constraints and relativistic causality are equivalent. Here, the authors show that, in the multipartite setting, the no-signalling condition is in general stronger than demanding relativistic causality.

Non-local quantum correlations between distant particles cannot be explained by signals propagating slower than the speed of light. It is now shown that they cannot be explained by hidden influences propagating faster than the speed of light either, because that would permit faster-than-light communication.
