  • Most of the current protocols for learning properties of quantum states are based on the assumption that the states are prepared in the same way over time. Here, the authors show a way to remove this assumption, while incurring only a polynomial increase in sample complexity.

  • Quantum communication schemes rely on cryptographically secure quantum resources to distribute private information. Here, the authors show that graph states—nonlocal states based on networks of qubits—can be exploited to implement quantum secret sharing of quantum and classical information.

  • Quantum technologies require an extremely precise functioning of their components which is ensured by sophisticated tools for device characterization. This Technical Review surveys and assesses the currently available tools according to their overall complexity, information gain, and underlying assumptions.
