Puri connects quantum-information theory with the noise a real device has, studying how control and error protection can work with that structure.
arXivarXiv / NaturePuri’s research asks how a device’s physical noise should shape the design of reliable computation. Her bias-preserving-gate work develops operations that retain an advantageous error structure during a calculation. Her coauthored Kerr-cat work connects that design question with experimental stabilization, gates and readout in superconducting oscillator systems. The Puri Group describes its focus as theoretical quantum information processing and quantum optics, with collaboration across experimental groups. That theory-to-device connection is useful for understanding why adding physical qubits alone is not a complete protection strategy: the code, operations, measurements and assumed noise all have to work together.
Yale School of Engineering & Applied SciencearXivarXiv / NatureYale University / Puri GroupYale School of Engineering & Applied ScienceA useful reading question: how does the structure of the noise affect the protection a device needs? Separate a proposed method from a measured improvement, then look for the device assumptions and the experimental test that would support the claim.

Keep in perspective
Yale pages use differing faculty-rank wording. This profile states the supported departmental appointments without inferring a promotion.
The group’s theoretical focus and experimental collaborations do not establish that every proposed protection method has been demonstrated on a device.
