Vanadium spin qubits as telecom quantum emitters in …
Solid-state quantum emitters with spin registers are promising platforms for quantum communiion, yet few emit in the narrow telecom band necessary for low-loss fiber networks. Here, we create and isolate near-surface single vanadium dopants in silicon carbide (SiC) with stable and narrow emission in the O band, with brightness allowing cavity-free detection in a wafer-scale material. In

The attractiveness of single crystal SiC in a variety of high power, high voltage, and high temperature device appliions such as electric vehicles and jet engines is counteracted by the very high cost of substrates. Precision cutting of multiple micrometre thick SiC layers and transferring them to lower cost substrates would drive the cost down and allow expanding the use of single crystal
Coherent control of single spins in silicon carbide
Here we demonstrate that missing atoms in a silicon carbide crystal can host single spins that are accessible by optical spectroscopy, with long coherence times even at room temperature. These results expand the interest of silicon carbide into the areas of quantum processing and integrated spintronics.

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive..
SiC Demand Growing Faster Than Supply
The silicon carbide (SiC) industry is in the midst of a major expansion campaign, but suppliers are struggling to meet potential demand for SiC power devices and wafers in the market. In just one example of the expansion efforts, Cree plans to invest up to $1 billion to increase its SiC fab and wafer capacities.

GaN on SiC: The Optimal Solution for 5G | Wolfspeed
However, when evaluating GaN solutions, a common debate emerges: Which is better for RF appliions, GaN on silicon (GaN on Si), or GaN on silicon carbide (GaN on SiC). While there are advantages to each approach, “infrastructure designers choose the solution that offers the best overall value,” says John Palmour, co-founder and CTO of Wolfspeed.
