About the Job

Requirements

  • A Ph.D. in Physics, Electrical Engineering, Materials Science, or a related field, with coursework background in condensed matter physics, quantum field theory, and quantum error correction control theory.
  • Experience using open-source and commercial software platforms such as PennyLane, TopQAD, scqubits, and SQuADDS.
  • Thorough understanding of superconducting qubit design theory and experience building in-house simulation tools and utilizing existing open-source tools.
  • Experience simulating low-temperature DC and RF measurement of qubit devices.
  • Proficiency in a wide array of programming languages, such as Python, Rust, TCL, or C, and the ability to choose the appropriate language for the task, including knowledge of or willingness to acquire knowledge of FPGA-based microcontrollers.
  • Ability to independently pursue fundamental research, including writing and publishing papers.
  • Ability to communicate complex data and insights clearly to technical and non-technical audiences.

Responsibilities

  • Lead and execute research projects in quantum computing superconducting-qubit simulation of multi-qubit systems using in-house and commercial simulation tools.
  • Collaborate with product teams to tackle novel challenges and develop solutions.
  • Stay current with industry and academic trends, publish papers, and present at conferences.
  • Develop and present detailed reports and visualizations to communicate findings, trends, and actionable insights to stakeholders at all levels.
  • Collaborate with room-temperature and low-temperature DC and RF metrology scientists to accurately describe realistic population-lifetime distributions, and with quantum error-correction information theorists to help choose quantum error-correction schemes.
  • Implement large-scale simulation models for quantum error-correction schemes, including distillation, on distributed networks of superconducting qubits.
  • Develop detailed understanding of how distributions of microscopic parameters affect the overhead needed to produce fault-tolerant logical qubits from physical qubits.
  • Develop detailed quantum-mechanical models of superconducting-qubit devices and theoretical and empirical models for their microscopic parameters.
  • Determine requirements for the distribution profiles of microscopic parameters of qubits and qubit gates to support fabrication of fault-tolerant quantum-computing systems with a minimal number of physical qubits.

About the Company

Western Digital

Makes hard drives for cloud and AI data centers

Western Digital, which goes by WD, designs and makes hard disk drives, mostly the high-capacity models that cloud and AI data centers use to store huge amounts of data cheaply. In 2013, its HGST unit shipped the first helium-filled hard drives, which fit more disks into each drive and use less power. Its drives store data on stacks of spinning magnetic disks, and the lineup runs from Ultrastar data center drives to WD Red and WD Purple drives for home servers and security cameras. WD makes its money selling these drives to cloud companies, PC makers, and retail shoppers. Western Digital was founded in 1970 and is based in San Jose, California, and in 2025 it spun off its flash memory business as Sandisk.
