Research Internships

• Amazon Braket Science (Quantum Research), Seattle, Washington May 2022- July 2022
  Advisor: Yunong Shi, Eric Kessler
  Project Summary: Shaped the vision of AWS Braket’s quantum software stack for near-term quantum computers by establishing a systematic view of noise-aware compilation workflow and software error-mitigation. I also implemented a software framework for efficient native gate selection for quantum circuits to improve the fidelity of quantum programs.

• Google Quantum AI Research, Remote, California May 2021- July 2021
  Advisor: Cody Jones
  Project Summary: Designed a reconfigurable, lightweight, low latency, accurate lookup table decoder for studying quantum error correction in the near-term.

• Microsoft Research, Redmond, Washington May 2019- July 2019
  Advisor: Nicolas Delfosse, Srilatha Manne, Doug Carmean
  Project Summary: Designed the micro-architecture of a fully pipelined Union-Find decoder to enable quantum error correction. This decoder is orders of magnitudes faster than existing designs (usually software). Also, proposed an optimized hardware-efficient system architecture to scale the design for large fault-tolerant quantum computers.

Full-Time Work Experience

• NXP Semiconductors, Austin, Texas May 2016- August 2017
  Worked as a Digital Design Engineer in the Digital Networking Group where I designed PCIe controller and energy-efficient Ethernet modules for networking SOCs. I also defined the architecture and designed the control and reset block to support integration of various IPs in different SOCs.
• LSI Corporation (now Broadcomm), Bangalore, India August 2012- August 2014
  Worked as an IC Design Engineer in the Custom Solutions Engineering Group where I worked on the design and verification of Ethernet and PCIe subsystems.
