TL;DR: In this article, the authors experimentally observed around 2 orders of magnitude circular dichroism (CD) enhancement in the visible region for cysteine molecules located in the hotspots of gold nanosphere clusters.

TL;DR: In this paper, the authors propose efficient, practical protocols for verifying arbitrary $n$-qubit Dicke states, based on Pauli measurements, which are readily applicable with current experimental techniques and are able to verify the robustness of hundreds of qubits.

TL;DR: In this article, a general definition of strong quantum nonlocality based on the local irreducibility is presented, and three sets of locally indistinguishable orthogonal product states are shown to explain the general definition.

TL;DR: The Raman spectra of the edges feature newly observed forbidden Raman modes, which are originally undetectable from the body region, by selecting the edge type and the polarization directions of the incident and scattered light.

TL;DR: In this paper, the authors proposed the concept of quantum process verification and established two efficient and practical protocols for verifying quantum processes, which can provide an exponential improvement over the standard quantum process tomography and a quadratic improvement over direct fidelity estimation.
