Quantum computers use qubits (quantum bits) to perform calculations. Qubits can be created by manipulating the spin states in quantum systems with magnetic fields. One major problem in the development of quantum computers is making qubits scalable. Hence, the quantum system must be constructed so that tens to hundreds of them can be physically imbedded into a single chip to form the basis of a quantum computer. One promising quantum system is the diamond nitrogen vacancy (NV) center. Current methods of controlling NV centers are not scalable, so adding multiple NV centers to a quantum computer design is difficult or infeasible. My SuperUROP project involves designing a CMOS microscale solenoid that emits microwave frequency magnetic fields to drive a single NV center. The solenoid should produce a strong magnetic field, yet be uniform enough so that several of them can be placed on a single chip without interfering with one another. The development of a scalable quantum system will pave the way for placing hundreds of qubits on a single chip.


I am participating in SuperUROP because it is a great opportunity to gain research experience. My background in both physics and electrical engineering has helped prepare me for this research. I am excited to learn more about the applications of quantum mechanics, practical electrical engineering skills, how to conduct quality research, and how to communicate and write about my research.
