Universal coherence protection in a solid-state spin qubit …
2020/8/12· Decoherence limits the physical realization of qubits and its mitigation is critical for the development of quantum science and technology. We construct a robust qubit eedded in a decoherence-protected subspace, obtained by applying microwave dressing to a clock transition of the ground-state electron spin of a silicon carbide divacancy defect. The qubit is universally protected …

Carbure de silicium — Wikipédia
Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique ultraréfractaire ultradure semiconductrice synthétique, qu''on peut trouver dans la nature sous la forme d''un minéral très rare, la moissanite.Grâce au procédé Acheson, depuis la fin du XIX e siècle, on sait produire industriellement de la poudre de carbure de silicium, qui servit d''abord comme abrasif.

Abstract: We present an analytical bond-order potential for silicon, carbon, and silicon carbide that has been optimized by a systematic fitting scheme.
Phase equilibrium in the formation of silicon carbide by …
2016/5/15· Methods of linear algebra were used to find a basis of independent chemical reactions in the topochemical conversion of silicon into silicon carbide by the reaction with carbon monoxide. The pressure–flow phase diagram was calculated from this basis, describing the composition of the solid phase for a particular design of vacuum furnace. It was demonstrated that to grow pure silicon carbide
Physics - Supersolid, with a Twist
The frictionless flow of atoms within solid helium may be confined to the axis of a screw disloion, a spiral defect like the one in this crystal of silicon carbide. × The strange quantum phenomenon known as supersolidity occurs when atoms flow without friction through a solid block of helium, possibly along a network of defects extending through an otherwise perfect crystal.
