Laboratory for hybrid quantum devices
Welcome to Laboratory for hybrid quantum devices
Laboratory for hybrid quantum devices is led by Professor Chunming Yin at School of Physical Sciences, USTC. Our research focuses on quantum computing and quantum sensing using semiconductor nanostructures. If you are interested in joining us, feel free to contact Chunming for lecturer, postdoc and PhD positions.
Research
1. Single spins with optical access
This project aims for optical cavity coupling between two or more single spins
to achieve long distance coupling between two spins. The ultimate goal is find
a way to build an integratable quantum computing platform with coupled spins, each of
which can be read out and controlled individually.
2. Quantum sensing with a single spin
In this project, a single ion or defect in solids can be used as atomic probe
to detect the local electric field, strain, magnetic field, as well as another
nearby charge and spin. This can be used to develop nano-scale sensor for
microelectronics and to build coupled spin/charge quantum systems.
3. New architecture for single spin detection
Towards the future, we are also working on designing and fabricating new
architectures, that would allow us to implement this single ion spectroscopy
on more types of defects with potentially higher sensitivity.
