What I'm working on
-
#spin-defects
Quantum sensing
Spin defects in hBN and NV centers in diamond, driven optically and by microwaves, read out electrically — for magnetic-field and nanoscale sensing.
-
#hybrid-systems
Hybrid quantum systems
Strong coupling between solid-state spin defects and microwave cavities, connecting long-lived spin states with microwave photons.
-
#photonic-info
Photonic quantum information
Single-photon experiments — high-dimensional gates, multi-photon entanglement, teleportation, nonlocality, and contextuality.
-
#instrumentation
AI + FPGA for quantum measurement
FPGA hardware for deterministic timing and real-time signal processing, with AI-assisted experiment control.
The aim is to move cleanly from a quantum mechanism to a measurement protocol—and from that protocol to an instrument that works outside a single demonstration.

Active projects
Electrical and microwave readout and coherent control of nitrogen-vacancy (NV) centers in diamond and single-photon emitters (SPEs) in two-dimensional materials. We study strong coupling between solid-state defects and microwave cavities, including superconducting resonators.
We develop compact and microscale quantum magnetometers, from portable sensing modules to chip-scale devices with integrated optical, microwave, and electrical control.
We study correlated phases and collective excitations in moiré materials at cryogenic temperatures, including electronic phonons in WS₂/WSe₂ electron crystals ↗ and gate-tunable ferromagnetism in the second moiré band of twisted MoTe₂ ↗.
An integrated control stack for planning experiments, coordinating instruments, and executing low-latency quantum measurement loops.
