Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.
The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!
We are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing €100 million of funding in 2025 to develop our unique technology.
Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future!
Alice & Bob is building fault-tolerant quantum computers based on cat qubits. As we move from lab to product, we are building a Quantum HPC team to interface between our deep tech and strategic clients—especially in the Defense and cybersecurity sectors.
We’re looking for a Cryptanalysis Specialist to leverage our cryptographic expertise within this team. Your mission: analyze the impact of quantum computing on cryptographic systems, develop credible technical narratives for Defense partners, and contribute to internal research aligned with our FTQC roadmap.
You may come from a cryptography background and want to move deeper into quantum computing—or the reverse. Either way, you’ll be expected to grow on both fronts.
Why Join Quantum HPC team?
- You’ll be at the forefront of quantum-era cryptographic risk
- Your work will directly support business strategy in high-stakes sectors like Defense and cyber
- You’ll collaborate with a multidisciplinary team of physicists, engineers, and strategic partners
- You’ll help shape the narrative of quantum cryptanalysis beyond the hype, backed by real technical credibility
Most cryptographers don’t get to work directly with a quantum hardware team. Most quantum scientists don’t get to shape real-world crypto applications.
Here, you do both.
