Job description

About Quandela

Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum solutions. The company’s unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient datacenters and scalability, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors.

Join Us at the Forefront of Quantum Computing Innovation

Description of the Team/Project

When will we be able to design a new molecule to cure cancer? Could RSA-2048 be decrypted in 2032? These are among the important questions posed by our clients.

Answering them requires quantum resource estimation: determining how a specific algorithm, applied to a given problem instance, could run on Quandela’s spin-optical quantum computer. This process—known as compilation—enables us to estimate the hardware resources required, including the number of components and the QPU size needed to solve the problem.

Resource estimation is one of the Algorithms, Applications and AI team missions you'll belong to.

Your Key Responsibilities

• Develop knowledge of fault-tolerant quantum computing, quantum algorithms for chemistry, quantum error correction, and—where needed—quantum compilation.
• Build a deep understanding of a quantum-chemistry algorithm to be defined, and break it down into its constituent subroutines.
• Review the literature on existing resource-estimation approaches for the selected algorithm.
• Adapt the resource-estimation methodology to the bi-planar SPOQC architecture for a specified quantum error-correction code.
• Compile the algorithm using pipe diagrams.
• Integrate the implementation into Quandela tools and evaluate resource requirements across a range of problem-instance sizes.

Requirements

Education & Background

• MSc student in Quantum Information Science, Quantum Computing, Physics, Computer Science, or a related field.

Technical Skills

• Knowledge of quantum error-correction codes, such as the surface code and honeycomb Floquet code.
• Understanding of fault-tolerant quantum computing, including lattice surgery and pipe diagrams.
• Familiarity with quantum algorithms for quantum chemistry, including quantum phase estimation, quantum singular value transformation, quantum signal processing, and Trotterization.
• Knowledge of quantum compilation techniques, such as rotation synthesis and ZX-diagrams.
• Familiarity with tools including CUDA-Q Logical, Microsoft Azure Quantum Resource Estimator, Qualtran, Stim, and TQEC.

Languages

• Fluent English, written and spoken, is required.

Benefits

• Swile Card (meal vouchers)
• 50% participation in transportation costs
• Possibility of remote work
• Internship Allowance between €1,200 and €1,400 per month
• 1,5 days off per month, cumulative
