## Job description

Job Description

As a Quantum Hardware Intern / Working Student you support the design, implementation, and scaling of advanced quantum photonic components for our quantum computing systems. You will contribute to experiments on prototype quantum photonic integrated circuits, assist in component and system‑level research, and help ensure reliable hardware integration in our lab environment.

You will work closely with quantum, photonics engineers, and control‑electronics specialists, building and testing optical and quantum‑optical setups around our quantum systems. In this role you gain hands‑on experience with state‑of‑the‑art Quantum Hardware and play a supporting part in advancing the technology that powers the quantum future.

- Perform design‑of‑experiment tasks for prototype under guidance from senior engineers.
- Assemble, test, measure, and characterize quantum photonic devices, with a focus 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.
- Contribute to internal projects by running experiments to schedule, tracking progress, and reporting deviations or issues.
- Interface with internal stakeholders for component sourcing, test planning, and technical coordination where required.
- Document laboratory findings in a clear and structured way and present results in internal meetings.

## Requirements

- Enrolled 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 lab equipment (lasers, fibers, detectors, tabletop optics) from courses, projects, or internships.
- Knowledge of integrated photonic components such as ring resonators, MZIs, beam splitters, and waveguide couplers.
- Basic understanding of quantum optics concepts (single photons, interference, coincidences, entanglement) and strong motivation to work in quantum technologies.
- Proficiency in Python for data analysis and simple experiment automation; familiarity with scientific libraries is a plus.
- Methodical, systematic approach to experiments and troubleshooting, with strong technical writing skills for internal documentation.
- Proactive, accurate, and independent working style, combined with the ability to thrive in a multidisciplinary team.
- Fluency in English, both spoken and written.

Exciting aspects of the role

- Work with technology at the cutting edge of quantum computer engineering, directly on Quantum PIC‑based processors and subsystems.
- Contribute to challenging, high‑tech projects, helping solve real hardware problems and enabling new quantum experiments.
- Be part of a dynamic, international team of quantum, photonics, and electronics experts, each bringing deep domain knowledge.
- Gain hands‑on experience assembling, testing, and characterizing quantum photonic hardware that bridges the gap from research prototype to deployable system.
- Play a meaningful role in driving innovation for a quantum future, with the potential to extend the internship into a thesis or early‑career opportunity depending on performance and company needs.

Join us in building the future of quantum technologies!

## About QuiX Quantum BV

## Company Overview
- **One-liner**: QuiX Quantum is the European market leader in photonic quantum computing, building deployable, integrated photonic quantum computers for data centers and HPC environments.
- **Entity Type**: Private (Series A, raised in July 2025)
- **Headquarters**: Enschede, Netherlands (with additional offices in Amsterdam, Netherlands; Ulm and Stuttgart, Germany)
- **Founded**: 2019
- **Founders**: Dr. Jelmer Renema (CEO) and Dr. Stefan Hengesbach (Chief Scientist) – full founding team details not publicly disclosed

## Core Business
- **Primary industry**: Photonic quantum computing hardware and systems
- **Target customers**: B2B – data centers, high-performance computing (HPC) centers, supercomputing facilities, research institutions, and government/defense organizations
- **Mission**: “Delivering quantum powerful and deployable at scale” – engineering photonic quantum computers that can run in standard data center environments without cryogenics

## Products & Services
- **Special Purpose Quantum Computer**: A photonic quantum computer optimized for specific applications (e.g., risk modeling, fraud detection) that operates in data centers, using hybrid quantum-classical architecture.
- **Quantum Photonic Processor**: A patented, reconfigurable photonic chip (20 optical channels, 2.9 dB loss, >99% transformation fidelity) that is plug-and-play, temperature stable, and fully calibrated – the core component of QuiX’s systems.
- **Universal Quantum Computer**: A field-upgradeable, modular photonic quantum computer (currently in development, with a public roadmap to logical qubits announced in May 2026).

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of $42.2M (LinkedIn data) across multiple rounds including a Series A of $17.5M (July 2025) led by European Innovation Council Fund and Invest-NL, and earlier grants from EIC Accelerator ($19.1M)
- **Notable Investors**: European Innovation Council Fund, Invest-NL, PhotonVentures, Oost NL, FORWARD.one
- **Growth Signals**:
  - More than 15 photonic quantum systems deployed in the field worldwide
  - First company to sell a universal photonic quantum computer in Europe (first customer: German Aerospace Center DLR)
  - Headcount growth of 50% year-over-year (70 employees as of mid-2026)
  - Recent milestones: demonstrated below-threshold error mitigation (April 2026), introduced PACU control unit (June 2026), unveiled path to logical qubits (May 2026)
  - 9 patents filed (topics: microtechnology, microwave technology, photonics)

## Competitive Advantages
- **Photonics platform**: Operates at room temperature using telecom-grade components – no cryogenics, lower total cost of ownership, easier to deploy and maintain than competing quantum platforms (e.g., superconducting, trapped-ion).
- **Lowest-loss photonic chips**: Proprietary silicon nitride CMOS-compatible chips achieve the industry’s lowest optical loss, essential for scaling to useful quantum computers.
- **Fastest clock speed**: Photonic quantum computing clock speeds of 100 MHz to 1 GHz, compared to <10 MHz for other platforms.
- **Error resilience**: Photonic systems are inherently more noise-resistant and allow more efficient error correction, reducing hardware overhead.
- **Drop-in ready**: Designed for standard data center and HPC environments, overcoming the “lab-only” barrier of other quantum hardware.

## Strategic Focus
- Scaling from special-purpose to universal photonic quantum computing, with a real-world roadmap to logical qubits.
- Deepening partnerships with HPC and data center operators across Europe and beyond.
- Continuing to drive down optical loss and improve component integration through a fabless manufacturing model.
- Expanding commercial traction beyond early adopters (e.g., DLR, University of Twente) into financial services, defense, and AI workloads.

## Why Work Here
- **Cutting-edge technology**: Work at the forefront of photonic quantum computing, a platform with strong commercial and scientific momentum.
- **Growth environment**: Rapidly scaling company (50% headcount growth in the past year) with clear product milestones and a live customer base.
- **International presence**: Four offices across the Netherlands and Germany (Enschede, Amsterdam, Ulm, Stuttgart) – likely offering hybrid or remote flexibility (not explicitly stated, but typical for tech scale-ups).
- **Hands-on impact**: Small team (70 people) means engineers and scientists can directly influence architecture and product direction.
- **Culture**: Focus on engineering excellence, field-upgradable modular systems, and a “fabless” approach that leverages external manufacturing partners for flexibility.
- **Talent development**: Active internship/master’s project opportunities (e.g., quantum light sources) and a growing team with open positions in quantum hardware, software, and photonics.
