TL;DR: In this paper, the authors present results on the equation of state in QCD with two light quark flavors and a heavier strange quark, and show that the effect of finite cutoff effects is significant for temperatures larger than about twice the transition temperature.

TL;DR: In this article, the first observation of stable single photon sources in an electronic and photonic device-friendly material, silicon carbide (SiC), was reported, which is a viable material for implementing quantum communication, computation and light-emitting diode technologies.

TL;DR: In this paper, the transition temperature in QCD with two light and one heavier quark mass on lattices with temporal extent N_t =4 and 6.457(7) was calculated.

TL;DR: In this article, the authors studied charmonium correlators in pseudoscalar and vector channels at finite temperature using lattice QCD simulation in the quenched approximation, and employed two analysis procedures: the maximum entropy method (MEM) for the extraction of the spectral function without assuming a specific form, to estimate the shape of spectral function, and the standard χ2 fit analysis using typical forms in accordance with the result of MEM.

TL;DR: In this paper, the authors demonstrate that spin ensembles can store quantum information over longer times than previously achieved, a significant step toward a quantum memory, and demonstrate that quantum information can be stored over longer periods of time than classical computers.
