TL;DR: This work reports a wholly artificial compound that acts on small molecules to create a gradient in their local concentration by using redox energy and precisely organized noncovalent bonding interactions to pump positively charged rings from solution and ensnare them around an oligomethylene chain, as part of a kinetically trapped entanglement.

TL;DR: In this article, a degenerate telecommunication wavelength entangled-photon source from an ultrafast pulsed laser pumped spontaneous parametric down-conversion (SPDC) was designed and realized, which shows simultaneously 97% heralding efficiency and 96% indistinguishability between independent single photons without narrowband filtering.

TL;DR: In this article, a green antihypertensive drug Losartan potassium (LP) with superior corrosion protection ability was developed for the first time, and the results indicated that LP exhibited superior mixed-type corrosion protection to steel at different temperatures owing to the formation of compact and ordered LP-adsorption film on steel surface.

TL;DR: In this paper, the authors demonstrate a secure key distribution that breaks the absolute key-rate limit of repeaterless QKD over a 509km-long ultralow loss optical fiber.

TL;DR: This work adopts the technology developed in the frequency and time transfer to lock two independent laser wavelengths and utilizes additional phase reference light to estimate and compensate the fiber fluctuation and calculates the secure key rates with the finite size effect.
