The P-Series Quantum is positioned between the excellent P-Series Quantum X and the more affordable M-Series Quantum. As you might guess from the naming scheme, almost all of Vizio's 2020 TVs feature quantum dots, microscopic nanocrystals that enhance color saturation. They also all feature full-array local dimming (FALD) backlights, which make for better than average contrast--especially during HDR viewing. Time in the lab revealed something we already assumed: the P-Series Quantum is excellent. In fact, the only reason to spring for the higher-end Quantum X is if you really want top-of-the-line brightness and color performance.
The TU8000 series is one of Samsung's mid-range offerings for 2020, and while it unfortunately doesn't come with quantum dots in tow, it nevertheless aims to impress you with performance that punches above its weight class, not to mention Samsung's usual penchant for sleek, modern design and snappy smart features. While the TU8000 manages to succeed in delivering commendable marks in certain categories, its overall performance isn't quite as good as other, similarly priced TVs. The reality is that this is an incredibly competitive price bracket, and although the TU8000 is solid, there are better options on the table for anyone who isn't committed to the Samsung lineup. The Samsung TU8000 comes with a built-in, Tizen-powered smart platform that will feel familiar if you've used a Samsung TV in recent years. We bought a 55-inch Samsung TU8000 for our lab tests, but different sizes of TVs in a series tend to perform very similarly to to one another.
Forgive the pun, but the Sony X800H is a land of contrasts. We love how bright it gets (particularly during HDR content), but its brightness is undercut by the TV's relatively shallow black levels. Its color production is fantastic for a mid-range TV, but its not as colorful as some of its rivals. All told, the X800H performs admirably and won't break the bank, but there are better-performing TVs in this price range. If you've got your heart set on a Sony brand TV, however, the X800H will probably be a good fit.
Efficient interfaces between photons and quantum emitters form the basis for quantum networks and enable optical nonlinearities at the single-photon level. We demonstrate an integrated platform for scalable quantum nanophotonics based on silicon-vacancy (SiV) color centers coupled to diamond nanodevices. By placing SiV centers inside diamond photonic crystal cavities, we realize a quantum-optical switch controlled by a single color center. We control the switch using SiV metastable states and observe optical switching at the single-photon level. Raman transitions are used to realize a single-photon source with a tunable frequency and bandwidth in a diamond waveguide. By measuring intensity correlations of indistinguishable Raman photons emitted into a single waveguide, we observe a quantum interference effect resulting from the superradiant emission of two entangled SiV centers.
In addition to its peak performance, its beautiful design, and its laundry list of extra features, the LG C1 is just a flat-out better value than this year's LG Gallery OLED (known as the "G1"). In fact, when it comes to picture quality, I'd wager that most folks wouldn't notice much of a difference between the two. The C1 is almost as good as the LG G1, but it's also a better all-around package than most of the TVs we've tested, too. From its incredible performance to its future-facing features, the LG C1 is easily one of the best TVs we've ever seen. Editor's note: Due to COVID-19 complications, this review leans heavily on test results in lieu of extended hands-on time with the TV.
