Description of the Team/Project
During this internship, you will work on the energetic cost and optimization of photonic fault tolerant quantum computing. Quantum computers are highly sensitive to noise, which induce errors. The latter can be mitigated or corrected at the expense of spending resources, which have an energy cost. The goal of the internship is to build a model tailored to Quandela's hardware, enabling to compute the energy costs of fault tolerant quantum computing. You will work in the Algorithm and Applications team, and build on previous work done for NISQ algorithms.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
BLOCK 1 — EXECUTIVE SNAPSHOT
This role addresses a critical pivot point in the maturation of photonic quantum computing: the energetic and resource overhead associated with achieving fault tolerance. As the quantum industry transitions beyond NISQ-era limitations, the feasibility of logical qubits and large-scale computation hinges on minimizing the physical resources—especially power consumption—required for quantum error correction (QEC) protocols. This internship is strategically positioned to develop the proprietary modeling framework necessary to quantify and optimize the power efficiency of Quandela’s specific photonic architecture, providing essential, data-driven intelligence for long-term hardware scalability and the commercial viability of future quantum data centers.
BLOCK 2 — INDUSTRY & ECOSYSTEM ANALYSIS
The quantum computing value chain is currently stratified, with disparate hardware modalities (e.g., superconducting, ion trap, neutral atom, photonic) all confronting the fundamental challenge of scalability subject to stringent physical constraints. Photonic quantum computing, while possessing distinct advantages in ambient operating temperature and networking potential, faces a TRL (Technology Readiness Level) constraint around highly efficient single-photon sources and low-loss interconnects. The primary scalability bottleneck across all platforms remains the prohibitive resource cost—latency, qubit count, and, crucially, energy—of implementing QEC to synthesize high-fidelity logical qubits. This resource expenditure is orders of magnitude higher than for classical computation, creating a sustainability and economic hurdle for mass adoption. The market structure mandates energy efficiency as a key competitive differentiator, particularly in the emerging quantum data center vendor landscape. A critical workforce gap exists in professionals capable of bridging theoretical quantum information science (specifically QEC and resource analysis) with practical hardware implementation metrics. This project directly contributes proprietary data to inform Quandela's hardware-software co-design efforts, providing crucial, quantifiable benchmarks against competing modalities and driving internal R\&D investment towards maximum energy-per-logical-operation throughput.
BLOCK 3 — TECHNICAL SKILL ARCHITECTURE
The required capabilities center on quantitative quantum resource analysis, which translates abstract quantum information theory (QIT) principles into executable engineering metrics. Mastery of QEC codes, particularly surface codes or related topological architectures suitable for photonic entanglement generation and manipulation, is the foundational domain knowledge. The execution outcome is a high-fidelity predictive energy model, necessitating strong proficiency in computational physics and algorithm implementation. The model must integrate constraints specific to the Quandela hardware stack—such as photon source efficiency, switching losses, and optical component noise profiles—to calculate the overall physical resources required per unit of logical computation. Python proficiency is essential not merely for coding, but for deploying numerical methods, statistical analysis, and simulation toolchains (e.g., QuTiP, ProjectQ, or custom internal frameworks) to ensure the model yields actionable, scalable data that informs physical layer engineering decisions. These skills enable throughput by identifying inefficient quantum circuit elements and drive scalability by ensuring future error-corrected systems meet industrial power-draw standards.
