Overview

Lead the development of the next-generation ion trap quantum computers and foundational technologies that will enable truly scalable and practical quantum computing. We are looking for AMO experimentalists with skills in operating lasers, optics, UHV systems and electronics, and with knowledge in cavity QED and quantum optics theory. In addition, researchers with expertise in microfabrication, integrated photonics and MEMS are highly valued.

 

Detail

  • Engage in the research and development of quantum hardware
  • Design experimental setups and undertake simulations
  • Build up the experimental setup and evaluate its operation
  • Data acquisition and analysis
  • Contribute to publications, conference presentations and intellectual property development

 

Research Themes

  • Cavity QED experiments directly connected to scalable ion-trap quantum computing.
  • Ion trapping: design, operation, and characterization of trapped-ion systems.
  • Development and integration of micro-optics and MEMS for quantum experiments.

 

Position Highlights

  • Close collaboration with theorists and engineers to translate concepts into working hardware and measurements.
  • Opportunity to play a central role in the real-world deployment of ion-trap quantum computers, working at the interface of cutting-edge research and system engineering.
  • Early-stage growth phase (second year since founding), offering broad responsibility, technical ownership, and meaningful influence over design choices and strategy.
  • English-speaking, international environment, collaborating closely with world-class researchers and engineers across theory, experiment, hardware, and software.
  • Strong emphasis on tight feedback loops between theory, experiment, hardware, and control software.

Qubitcore is a deep tech startup originating from the Okinawa Institute of Science and Technology (OIST) and founded in 2024.

The company is developing and delivering next-generation ion trap quantum computers designed to tackle problems that are computationally intensive, in fields such as drug discovery, climate modeling, financial simulations, and generative AI.

Its mission is to bring quantum computing into real-world applications with greater speed and precision.

Qubitcore’s headquarters is located in Yokohama, while its R&D center operates within the OIST campus in Okinawa. Currently, the team consists of 6 members, working closely with OIST to realize Japan's first distributed quantum computer.

Qubitcore's distributed architecture connects multiple quantum processing units (QPUs) via photonic links to form a high-performance, networked quantum system. This approach enables large-scale quantum computation that was previously impractical, opening new frontiers in quantum technology.
