Quantum Algorithms Theorist - Resource Estimation and Design(13804)
職種Position R&D / Engineer /Technician (AI, Data)
会社概要Company profile This is with a deep-tech startup developing and commercializing world-leading neutral-atom quantum computing systems, one of the most promising next-generation computing architectures.

The company was established in collaboration with leading quantum physics research groups in Japan and is working toward the practical realization of quantum computers as a next-generation computational platform. Through joint research initiatives with universities, national laboratories, and global technology partners, the team is advancing quantum hardware development for future industrial applications and international markets.

Quantum computing is expected to transform industries such as:

drug discovery
advanced materials design
artificial intelligence
financial optimization
energy systems

Among multiple quantum architectures, the company focuses on neutral-atom quantum computing, widely considered one of the most scalable and promising approaches for large-scale quantum processors.

This role offers a rare opportunity to contribute not only to research infrastructure but also to the real-world deployment and industrialization of next-generation computing technology.
仕事内容Job description This role involves incorporating hardware-aware constraints into the estimation of computational resources necessary for running quantum algorithms on neutral atom devices. This includes algorithm selection, circuit design, and logical resource estimation for application across many high-impact domains. We are looking for candidates to bridge application-level algorithm development to the constraints of hardware, to specify the scale of machine necessary to execute them, and to realise practical quantum advantage.

[Responsibilities]
-Identify, design, and evaluate viable quantum algorithms for neutral atom quantum computers.
-Compare algorithm implementations and identify trade-offs between accuracy, space costs, runtime, and demands of physical hardware.
-Incorporate hardware-aware constraints to implement algorithms that take advantage of neutral atom capabilities such as long-range connectivity and parallel operations.
-Evaluate and refine the logical resource costs of distinct fault-tolerance frameworks together with QEC theorists to estimate the full physical cost of algorithms under realistic assumptions.
-Communicate algorithmic costs and trade-offs, including the scale and requirements of future devices, to both internal technical staff and external audiences.
応募資格Requirement [Required Qualifications]
-PhD or equivalent in Quantum Information, Physics, Computer Science or Mathematics.
-Strong background in quantum algorithms and working with quantum circuits.
-Experience with quantum algorithms such as Hamiltonian simulation, quantum chemistry and materials simulation.
-Experience with resource estimation for fault-tolerant quantum computing with relevant experience in research publication.
-Ability to communicate algorithmic costs and trade-offs to both internal technical staff and external audiences.
-Ability to work alongside and collaborate with people across the diverse disciplines of engineering, experimental physics and software.

[Preferred Qualifications]
-Familiarity with neutral atom hardware constraints.
-Familiarity with different frameworks for fault-tolerance and how to evaluate logical gate costs under each framework.
