Job summary

Photonic is seeking a Senior Quantum Error Correction Developer in British Columbia (Hybrid) to develop fault-tolerant logical operations for LDPC codes and contribute to the quantum compiler stack. You will work across theory and hardware integration, shaping scalable logical qubit platforms.

The role emphasizes collaboration with compiler, hardware, and software teams, plus demonstration of strong mathematical and coding skills for simulation-driven development.

Qualifications

• Advanced degree (M.Sc. or Ph.D.) in math, physics, or CS with focus on quantum error correction.
• Strong math background in linear algebra, representation theory, group theory, or topology.
• Experience with homomorphic/homological measurements, lattice surgery, or magic state distillation.
• Proficiency in Python; experience with QEC simulation tools is a plus.
• Ability to collaborate across teams in a product-driven environment.

Responsibilities

• Develop fault-tolerant logical operations for quantum LDPC codes and other code families relevant to Photonic's architecture, using techniques such as homomorphic measurements, and generalized lattice surgery
• Produce logical primitives (e.g., logical Pauli measurements, entangling gates, magic state injection) for various code families, suitable for integration into the quantum compiler stack
• Analyze and optimize the resource requirements of proposed logical operation schemes, including ancilla qubits, circuit depth/time steps, and magic state factory requirements
• Develop and validate decoding strategies compatible with proposed logical operations
• Leverage the theory of covering spaces, chain complexes, and homological algebra to construct measurement protocols for general CSS and LDPC codes
• Characterize the fault-tolerance properties (threshold, distance preservation, single-shot capability) of proposed schemes through rigorous analysis and numerical simulation
• Collaborate with the compiler team to ensure logical primitives are compatible with the quantum compilation pipeline and can be efficiently scheduled
• Collaborate with hardware, systems, compilers, and software teams to ensure logical operation designs align with hardware constraints, compiler interfaces, and system-level requirements
• Translate theoretical results into engineering specifications and simulation-ready implementations
