About the Job

Requirements

  • Enrollment in a Master's or advanced Bachelor's program in experimental physics, photonics, quantum engineering, or a related applied science discipline.
  • Hands-on experience with optical laboratory equipment, including lasers, fibers, detectors, and tabletop optics, from courses, projects, or internships.
  • Knowledge of integrated photonic components such as ring resonators, Mach–Zehnder interferometers, beam splitters, and waveguide couplers.
  • Basic understanding of quantum optics concepts including single photons, interference, coincidences, and entanglement.
  • Proficiency in Python for data analysis and simple experiment automation.
  • A methodical and systematic approach to experiments and troubleshooting, with strong technical writing skills for internal documentation.
  • Fluency in English, both spoken and written.

Responsibilities

  • Perform design-of-experiment tasks for prototypes under the guidance of senior engineers.
  • Assemble, test, measure, and characterize quantum photonic devices, focusing on scalability and reproducibility.
  • Develop, align, and maintain optical and quantum-optical setups in the laboratory.
  • Collaborate with design, production, and quantum science teams to integrate quantum hardware into larger system demonstrators.
  • Run experiments to schedule, track progress, and report deviations or issues for internal projects.
  • Interface with internal stakeholders for component sourcing, test planning, and technical coordination where required.
  • Document laboratory findings clearly and systematically and present results in internal meetings.

Desired Qualifications

  • Familiarity with scientific Python libraries.
  • Potential to extend the internship into a thesis or early-career opportunity, depending on performance and company needs.

About the Company

QuiX Quantum

Photonic quantum processors for room-temperature computing

QuiX Quantum develops quantum photonic processors and complete quantum computing systems that operate at room temperature using photons in reconfigurable silicon nitride waveguides (TriPleX) to form universal, tunable interferometers. A fabless model means they design the chips and IP in-house but contract fabrication to specialized foundries; their processors route photons through low-loss on-chip circuits to realize quantum interference. Compared with others, they emphasize room-temperature photonics, high qumode counts on compact chips, and a proven track record with large-scale processors and a DLR sale, plus cloud-based remote access. Their goal is to deliver a first-generation universal photonic quantum computer by 2026 and enable broader access through cloud services and collaborations.
