Just SiC. Silicon Carbide Semiconductor Research May Pan Out for Quantum Information Processing

Silicon is in the scope for many quantum computing research teams. But what exactly is SiC?  To understand the application to quantum computing in this piece, we had to sort it out.  From ROHM Semiconductor: “SiC (silicon carbide) is a compound semiconductor composed of silicon and carbide. SiC provides a number of advantages over silicon, including 10x the breakdown electric field strength, 3x the band gap, and enabling a wider range of p- and n-type control required for device construction.  The result is breakthrough performance, not possible with silicon, making it the most viable successor for next-generation power devices. A variety of polytypes (polymorphs) of SiC exists, each with different physical properties. Of these polytypes, 4H-SiC is the most ideal for power devices.”

Researchers Make Tuneable Optical SiC Chip

In brief…

+  American researchers have created a SiC photonic integrated chip that can be thermally tuned by applying an electric signal. They think the approach could one day be used to create a large range of reconfigurable devices such as phase-shifters and tuneable optical 0couplers needed for networking applications and quantum information processing.while also being biocompatible and operating at wavelengths from the visible to infrared.

“Devices such as the one we demonstrate in this work can be used as building-blocks for next generation quantum information processing devices and to create biocompatible sensors and probes,” said the paper’s first author Xi Wu.

+  Although most optical and computer chips are made of silicon, there is increasing interest in SiC because it exhibits better thermal, electrical and mechanical properties than silicon

+  SiC is particularly attractive for quantum computing and communication applications because it has defects that can be optically controlled and manipulated as quantum bits, or qubits. Quantum computing and communication promises to be significantly faster than traditional computing at solving certain problems because data is encoded in qubits that can be in any combination of two states at once, allowing many processes to be performed simultaneously.
