Postdoctoral Researcher or Research Scientist in Hybrid Quantum Circuits, RIKEN Center for Quantum Computing (26-1488)

Job Description

This postdoc in superconducting quantum circuits is with the Hybrid Quantum Circuits Research Team at the RIKEN Center for Quantum Computing, near Tokyo. RIKEN is hiring a few postdoctoral researchers or research scientists. They will design and test qubits for a fault-tolerant superconducting quantum computer.

At a glance

• Positions: A few Postdoctoral Researchers or Research Scientists (job 26-1488)
• Where: RIKEN Wako Campus, Wako, Saitama, Japan; on site
• Team Director: Atsushi Noguchi
• Pay: From 400,000 yen a month (postdoc) or 470,000 yen a month (research scientist), with allowances
• Contract: 1 year, renewable on evaluation up to 31 March 2031
• Apply: open until filled (re-checked 13 November 2026)

About the hybrid quantum circuits work

• Work on “Design and Characterization of Qubits for Integrated Circuits” in the Moonshot Goal 6 project to build a fault-tolerant superconducting quantum computer
• Do research on quantum electronics with superconducting circuits
• Do research on hybrid quantum systems, such as microwave resonators and trapped electrons controlled by superconducting circuits

The team builds long-lived quantum systems and controls them with superconducting circuits. Its aim is to beat their natural lifetimes using quantum error correction. RIKEN calls you a Postdoctoral Researcher if your doctorate is 5 years old or less, and a Research Scientist if it is older.

Why this role matters

Japan’s Moonshot programme funds a long push towards an error-corrected quantum computer. This team works on the qubits that such a machine needs. The contract can run to 2031, which gives time for deep work.

What RIKEN is looking for

• A doctorate in a related field, or one expected by the hiring date
• Research experience in quantum technologies
• Ability to work on site at Wako; this post does not allow remote work

Pay and location

The ad gives the starting pay as at least 400,000 yen a month for a Postdoctoral Researcher and at least 470,000 yen a month for a Research Scientist. Both figures include the discretionary work allowance. Commuting and housing allowances are paid, and social insurance applies. The contract is for one year and can be renewed on evaluation up to 31 March 2031. The first two months are a trial period. The ad says the post is open until filled, with a start as early as possible.

How to apply

Apply through the official RIKEN job posting. RIKEN’s posting does not give a closing date, so the role is open until filled; ResearchJobs.in will re-check this listing on 13 November 2026.
