I attended the LIDS student conference to give a presentation titled “Harnessing Quantum Control for Quantum Sensing and Simulation” in session “Information and Networks”. My presentation won the best presentation award!

See my recent results published on PRL and highlighted by MIT News. We develop an unbalanced echo technique to extend the dephasing time of a nuclear spin ensemble to the single spin limit, paving the way for building better gyroscopes and memories.

Please also see our accompanying theoretical work on first-principles calculation of the temperature-dependent transition energies in spin defects published on JPCL.

We recently built a novel fast wide-field quantum sensing setup integrated with a SPAD array, capable of sensing fast dynamics with high sensitivity. The work is now published on Advanced Quantum Technologies and highlighted by Advanced Science News.

Our recent work on manipulating solid-state spin concentration through charge transport is now published on PNAS and is highlighted by MIT News. With the capability of tuning spin density in solid-state defect platforms, researchers may be able to develop better quantum sensors or quantum simulators! The work is also reported by 光子盒.

I am honored to be featured by MIT Center for Quantum Engineering!

I graduated from MIT in June of 2023 with a Ph.D. in Quantum Science and Engineering, and started as a postdoctoral associate at MIT to explore quantum physics with cavity QED and atom array systems!

Excited to contribute to Haowei’s project on ONQ effects, explore their application in optical control of nuclear spins and laser cooling of nuclear magnons, see our results published in PRX and PRL.

It is a great honor for me to win the competitive Princeton Quantum Initiative postdoctoral fellowship!

I obtained the MathWorks graduate fellowship, see this profile page at MIT School of Engineering. “Guoqing Wang is a PhD candidate who is exploring the frontiers of physics and quantum science for the purpose of building fundamental theory and creating next-generation quantum-based technologies. His work has already yielded breakthrough applications, such as high-performance quantum sensors, and contributions in theory, including quantum information protection and simulation of novel quantum phases. As a MathWorks Fellow, he will advance several ongoing projects, all powered by MATLAB tools that he has utilized and/or created. These projects explore: protection and control of large-scale quantum devices and the qubits that comprise them; simulation of novel phases and symmetries and the development of periodically driven quantum systems; and creation of improved quantum sensors for the nanoscale detection of vector AC fields—a valuable capability in fundamental physics research, microwave engineering, material science, and biological applications. Guoqing’s wide-ranging and innovative work is already contributing to multiple projects within and beyond MIT and has potential to impact future research in the field. As his work progresses, he looks to create a full MATLAB-based toolkit for the quantum research community.“

My recent work on developing a quantum mixer to sense arbitrary frequency electromagnetic signals is now published on PRX and is featured in Physics! It is also highlighted by MIT News and 光子盒.
