Headquartered in Broomfield, Colorado, Quantinuum is a full-stack quantum computing company formed through the merger of Honeywell Quantum Solutions and Cambridge Quantum. The firm develops trapped-ion quantum hardware alongside specialized software platforms, including quantum chemistry engines, compiler toolkits, and quantum-cybersecurity applications.

Quantinuum is seeking a Fault Tolerant Quantum Algorithms Researcher in our Broomfield, CO location with expertise in physics, chemistry, computer science, or mathematics to design fault-tolerant quantum algorithms for our trapped-ion quantum processors. You will work with an interdisciplinary team of quantum algorithms and error correction researchers and implement your ideas on the world’s most powerful quantum computers. Your work will advance quantum algorithms and fault-tolerant quantum computation methods, and will include opportunities for collaborative research with academic, government, and industry partners.

Key Responsibilities:

  • Conduct fundamental research in fault-tolerant quantum algorithms, and the codesign of algorithms and error correction
  • Work with an interdisciplinary team of quantum hardware, software, algorithms, and error correction researchers to advance fault-tolerant quantum computing (FTQC)
  • Implement ideas on the worlds’ most powerful quantum computers, and advise on the development of future quantum computing architectures
  • Conduct collaborative FTQC research with external academic, national lab, and commercial partners

You Must Have:

  • PhD required prior to start
  • Minimum 5+ years (PhD inclusive) experience with research in quantum algorithms, theoretical physics or chemistry, or quantum error correction, demonstrated through a strong publication track record
  • Minimum 2+ years’ experience with scientific programming in Python, C++, Rust, or a comparable language(s)
