Research interest

In the quantum metrology problem, one wishes to use a quantum resource to measure a signal with known structure but unknown strength. Consumption of quantum resources allows measurements to be made more precise beyond what is classically possible. Quantum metrology promises to usher in sensors with unprecedented precision. I like to design robust near-term schemes for quantum metrology with noisy probe states, drawing from my experience of designing customized quantum codes.

Quantum error correction protects fragile quantum data. Schemes of quantum error correction can be optimized for different quantum technologies.

Quantum mechanics enhances the precision of measurements. Quantum metrology is a use-case of quantum technologies that promises to allow us to have sensors with unprecedented accuracy.

A quantum memory is an essential technological primitive for quantum computation and communication.
