Quantum Scientist - Algorithms

About the role

The Quantum Scientist - Algorithms role at Xanadu involves joining a technical team dedicated to developing fault-tolerant quantum computers. The role focuses on discovering and optimizing quantum algorithms, particularly those relevant to quantum chemistry and materials science. Collaboration with industry, government, and academic partners is essential.

Responsibilities

• Design and pioneer innovative quantum algorithms tailored for fault-tolerant quantum computers.
• Improve algorithm efficiency by minimizing qubit counts, gate complexity, and overall resource requirements.
• Identify high-value applications targeted at quantum chemistry and materials science.
• Demonstrate the feasibility and scalability of new algorithms and applications through rigorous resource estimation.
• Collaborate directly with industry leaders to deliver solutions for real-world problems.
• Work alongside compilation and quantum error correction (QEC) experts to compile quantum algorithms to fault-tolerant architectures.
• Collaborate with PennyLane software developers to create state-of-the-art tools for quantum algorithms research.
• Author high-quality scientific papers, technical reports, and comprehensive documentation.
• Generate valuable intellectual property and actively support the filing of related patents.
• Present research findings to strategic partners and at premier conferences and events.

Requirements

• Must be currently authorized to work in the United States on a full-time basis.
• PhD in Physics, Computer Science, Chemistry, Mathematics, Engineering, or a related quantitative discipline — or equivalent practical experience.
• Strong track record of research accomplishments in quantum computing, evidenced by publications, patents, or technical work.
• Deep knowledge of fundamental concepts in quantum algorithms, such as Hamiltonian simulation, Trotter product formulas, quantum signal processing, linear combination of unitaries, amplitude amplification, quantum phase estimation, and quantum read-only memories.
• Expertise in computational methods for quantum chemistry and materials science, for example active space constructions, coupled cluster, and DMRG.
• Capacity to thrive in an interdisciplinary team environment and drive independent research when required.
• Excellent communication skills, with a proven ability to convey complex technical ideas to specialist and non-specialist audiences.
• Strong self-management skills to balance individual project priorities, deadlines, and deliverables in a fast-paced environment.

Qualifications

• Expertise in spectroscopy simulations, quantum embedding methods, and battery applications (preferred).
• Experience performing constant-factor resource estimation for fault-tolerant quantum algorithms (preferred).
• Experience collaborating with industry or government partners (preferred).
• Strong software development and scientific programming skills in Python, preferably with a proven track record of contributing to open-source scientific libraries (preferred).
• Solid understanding of quantum error correction and fault-tolerant architectures (preferred).
• Knowledge of quantum compilation techniques (preferred).
