Quantum Sensing and Metrology
We generalized quantum signal processing from spin dynamics to simulate continuous variable systems, and use it to design algorithmic quantum sensing protocols with much greater flexibility which achieves beyond the Heisenberg limit sensing capability for decision problems.
Quantum Digital-Analog Signal Processing
The hallmark of digital signal processing is Fourier transform and filter design. Envisioning a quantum future with an increasing demand of processing quantum signals and data, we seek to harness the power of quantum systems and computers for signal processing in the mixed digital-analog fashion.
