Dr. Yu-Chen Chen obtained his Ph.D. at Oxford University in UK. His research is focused on the single spin defects in wide bandgap materials and their quantum applications. His research topics include developing new methods to engineer single defects with good spin and optical coherence properties, finding new spin defects in other wide bandgap materials, and understanding their spin dynamics.

Dr. Chen developed a laser writing method that uses a femtosecond pulsed laser to fabricate nitrogen-vacancy (NV) centres with perfect optical coherence properties in diamonds. The traditional engineering methods cannot generate the NV with good optical coherence properties, as it is the critical requirement to entangle NV centres. Dr. Chen’s laser writing method can achieve this result because it generates less damage to the diamond structure. This method has been filed as a US patent. Dr. Chen also researched the spin dynamics of new spin defects in hexagonal boron nitride 2D materials.

After Dr. Chen joins the quantum photonics team, he will be dedicated to researching the single spin defects in nitride materials and the single spin defects with telecom band emission. His research aims to make great progress in the solid-state qubits’ applications in quantum communication, as well as contribute to nurturing talents and improving the industry development in Taiwan.

Dr. Yu-Chen Chen has been an assistant research fellow at the Research Center for Applied Sciences since April, 2022.
