Research Scientist (Device Fabrication)

RESEARCH SCIENTIST, Device Fabrication: Located at Northwestern University, to join the group of Professor Enectali Figueroa-Feliciano and Dan Baxter. The successful applicant will join the Figueroa Group at Northwestern, and lead the qubit and detector fabrication effort. We are building various transmon-based qubit computation and sensor devices, as well as MKIDS and TES-based detectors for particle physics. Preference will be given to candidates with demonstrated leadership of research groups, supervision and mentoring of students, and familiarity with successful grant writing.

The Figueroa Group is currently involved in several projects involving device fabrication:

  • We are currently designing transmon-based qubits to study TLS noise, quasiparticle poisoning, the quantum Zeno effect, correlated errors, cross-talk, and phonon interactions in qubits. We are also working on training AI to design qubits, and will be fabricating and validating AI qubit designs.
  • We are part of the HARMONICA project, and DARPA-funded effort to design and build QIS-based neutrino detectors. As part of this project, we are designing and fabricating quantum acoustic detectors and quantum parity detectors; both using transmons for their readout.
  • In addition to transmon-based devices, we are fabricating MKID and TES-based detectors for a variety of projects in QIS, dark matter, and neutrino physics.

REQUIREMENTS: A minimum of three years of experience working in a lithography fabrication environment. Applications will be evaluated on a rolling basis until the position is filled.

Please submit a letter of interest and curriculum vitae, and have three letters of recommendation sent to: figueroagroup-jobs@northwestern.edu


Postdoctoral Researchers in Particle Physics and Quantum Computing

Located at Northwestern University, to join the group of Professor Enectali Figueroa-Feliciano. The successful applicant will play a leading role in the CosmiQ quantum sensing and computing initiative with Fermilab.

The Figueroa Group is currently involved in several projects involving cryogenic detectors:

  • CosmiQ is an R&D effort to develop qubits and related technologies for both particle sensing and quantum computing with members from Fermilab, IIT, and Northwestern. Northwestern is an active partner working on qubit measurement, modeling, and fabrication. We are focusing on the interplay between radiation and qubits, understanding how to maximize/minimize qubit sensitivity for sensing/computing. We are designing and fabricating transmon-based qubits to study and manipulate these effects, and on strategies for enhancing robustnes and adapatbility of qubits for fault-tolerant quantum computing.
  • R&D at Fermilab: Our group, in collaboration with Fermilab, operates two sister facilities: the Northwestern EXperimental Underground Site (NEXUS), and the Quantum Integration and Experimental Testbed (QUIET). Both are 100 meters underground in Fermilab’s MINOS tunnel.

    • REQUIREMENTS: A Ph.D. in physics. Candidates' background must be in experimental nuclear or particle physics, superconducting qubits and quantum computing, or experimental condensed matter physics. Applications will be evaluated on a rolling basis until the position is filled.

    Please submit a letter of interest and curriculum vitae, and have at least two letters of recommendation sent to: figueroagroup-jobs@northwestern.edu
