Quantum-Enhanced Biomedical Imaging and Treatment
The last decades have witnessed how quantum coherence transformed a multitude of atomic and optical technologies.
Applying to biological processes, a new set of tools can be developed that enable unprecedented understanding of ourselves
and the nature, and eventually help battle against diseases.
Quantum Processing on Chip
There has been tremendous progress in contructing quantum computers using matter qubits,
such as trapped atoms, ions, and superconductors. We explore an all-photonics avenue using lowloss linear optics
and extreme nonlinear optics on chip to build room-temperature, robust, scalable, integrated quantum circuits, which
could demonstrate quantum supremacy for certain limited computational tasks in the near term but eventually leads to
general-purpose photonic quantum computers in the future.
High-dimensional Quantum Communications
We are undertaking novel engineering approach to robust quantum communications in challenging environment
including vastly high-dimensional coding, and choosing unconventional wavelengths for free-space links.
Quantum remote sensing
We have demonstrated quantum parametric mode sorting, a programmable filter based fast nonlinear optics,
overcome the performance limit of linear time-frequency filters. It opens doors to exotic applications
in remote sensing and ranging.
We utilize new capabilities through advanced quantum photonics to detect and assess atmosphere conditions, chemical compounds, etc., from distant locations.
Information crisis is impending, if not here already. Existing
platforms have proven unable to handle booming information. We work to address this challenge
by pushing all-optical technologies to the attojoule regime, which amounts to ~10
photons per pulse.
