About this role

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're a diverse team of 250+ brilliant minds from over 35 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!

Benefits:

Our success is your success: own it with our BSPCE plan
Direct IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture.
Flexible remote policy, up to 40 % a month
A Parental plan including additional benefits such as crèche support or additional days-off to take care of under 12 years old children
Subsidized membership with Urban Sports Club
Mental health support with moka.care
25-day vacation policy (as per French law) + RTT
Half of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle users
Competitive health coverage, with Alan.
Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
French language courses covered by the company for those interested

Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.

You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!

We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.

Research & Technical Development

Lead or contribute to a quantum applications/algorithms project, potentially in collaboration with academic or private partners

Develop new applications — from initial state preparation to gate count optimization to translating use cases into algorithms

Define, improve, or optimize (parts of) our compilation architecture

Build and improve tooling for applications or compilation work

Implement code in Qualtran and determine/optimize the logical and cat qubit resources required to run it

Publish research findings (target: 1 paper/year)

Co-author patents and produce research documentation that strengthens our IP portfolio, when relevant

Represent the company in scientific collaborations, at conferences, or in review/commentary of external papers, when relevant

Team & Company Contribution

Share learnings and insights through the L2/L3 guild

Contribute to and improve team processes and cross-team interfaces, taking ownership of specific areas

Provide technical insight and expertise on research projects owned by others

Support other teams by lending your expertise — including representing the company to (potential) partners and clients
3+ years of hands-on research experience

PhD in quantum algorithms, quantum information theory, mathematics, or a related field (e.g., quantum chemistry)

Strong knowledge of quantum information and algorithms (e.g., qubitization, Trotterization, spin models, the Hubbard model, tensor networks)

Understanding of how algorithms connect to compilation and error correction (e.g., time-optimal computation, Pauli frames, lattice surgery, magic state distillation/cultivation, LDPC codes)
