Researchers develop new solid-state quantum structure material operational at room temperature
+ The Ulsan National Institute of Science and Technology (UNIST) said in a statement on November 1 that its research team has developed a solid-state quantum structure material using silicon carbide nanowires.
South Korean researchers have developed a new solid-state quantum structure material using silicon carbide nanowires. The new material featuring a fast recombination time exhibit outstanding optical properties of high-brightness single photons and is operable at room temperatures.
+ Conventional polyatomic crystal-based structures can have errors, caused by crystallographic defects such as vacancies and stacking faults when processing electronic spin or light particles as qubits. The new nanowire-based system uses coupled point-planar defect complexes in the nanowire to lead an unusually strong zero-phonon transition to achieve highly efficient quantum interactions between multiple qubits.
+ “Instead of using high-quality single-crystal material like the diamond, we were able to create a stable, fast and efficient room-temperature quantum system using low-quality materials,” UNIST’s head researcher Kim Je-hyun was quoted as saying. He said that the newly-developed system can be applied to various fields including quantum computing, quantum communication, and sensors.
