QUANTUM SCIENCE & ENGINEERING AT HRL

HRL Laboratories is a world leader in developing solid-state technology for quantum computing and networking. We are advancing a variety of technologies including silicon heterostructure quantum dot qubits, silicon carbide photonics, superconducting nanowire single photon detectors, chip-scale atom-optics components, and microwave-dot hybrid systems. These efforts build on our decades of experience in research and development and draw on robust collaborations with academia.

HRL’s campus in Malibu, CA is equipped with on-site epitaxial semiconductor growth tools, a state-of-the-art 10,000-square-foot nano-fabrication cleanroom facility, high-performance computational resources for theory and simulation, and cryogenic test and measurement laboratories. It is the same site that originated world-changing inventions such as the self-aligned gate MOSFET and the world’s first laser.

What differentiates HRL’s approach from other professional quantum efforts?

  • Long-term strategy – The potential of quantum technology extends far beyond immediate applications, but will take time to realize.
  • Collaborative – We organize around the fact that quantum engineering requires a highly diverse set of skills and backgrounds.
  • Vertically integrated – We leverage the rapid development cycles made possible by on-site epitaxial semiconductor growth, device fabrication, software development, qubit testing, and theoretical analysis.
  • Pioneering – Many of our technological approaches are not yet mainstream, but have demonstrated and compelling advantages.
  • Experience – HRL has a long history as a leader in key enabling technologies such as materials growth and characterization, high-performance circuits, advanced packaging, and quantum information science.

Scientists, engineers, software developers, graduate students, and undergraduate students who are interested in quantum science and engineering are encouraged to apply to our open positions.
