Shruti Puri

Designs quantum operations and error-correction methods that exploit structured noise, linking the theory of cat-qubit gates with experimental stabilization, control and measurement of superconducting oscillator qubits.

Puri’s work asks how a qubit’s physical noise can shape the design of a reliable computer. Her bias-preserving-gate research develops operations that maintain an advantageous error structure instead of destroying it during computation. The Kerr-cat experiment supplies a complementary physical demonstration, combining stabilization, gates and readout in a superconducting oscillator. These contributions connect device behavior with fault-tolerant architecture. They support an approach to reducing the demands of error correction under stated assumptions, rather than eliminating errors altogether.
