Join our team

At Qubitcore, we are redefining what's possible in Ion Trap Quantum Computing: solving Scalability and Error Correction challenges better than everyone else.

We're backed by leading deep-tech venture capitals and moving fast to scale our impact. We welcome new talents to help us along this exciting journey.

Open positions:

Researcher (Experimental/AMO)

Full Time
Okinawa

Areas of expertise: AMO Physics, Quantum Optics, Cavity QED, Laser Systems, UHV, Quantum Information Science

Lead the experimental development of next-generation ion-trap quantum computers. We are looking for AMO experimentalists with skills in operating lasers, optics, UHV systems and electronics, with knowledge in cavity QED and quantum optics theory. Researchers with expertise in MEMS, integrated photonics, and microfabrication are also highly valued.

Researcher (Theoretical/AMO)

Full Time
Okinawa

Areas of expertise: AMO Physics, Quantum Optics, Photonic Quantum Networking, Cavity QED

Lead the photonic interconnect theory effort at the heart of our distributed architecture. Design and analyze ion–photon entanglement generation schemes, model photonic link performance, and develop quantum networking protocols that connect our QPU modules. Work hand-in-hand with experimentalists to translate models into real hardware performance.

Researcher (Theoretical/QEC)

Full Time
Okinawa

Areas of expertise: Quantum Error Correction, Fault-Tolerant Quantum Computing, Quantum Information Theory

Own the full error-correction stack—from building system-level error budgets to designing QEC codes and fault-tolerant protocols that run on real ion-trap hardware. Work closely with experimental and hardware teams to co-design the QCCD architecture and drive our path toward fault-tolerant quantum computation.

Engineer (Hardware)

Full Time
Okinawa

Areas of expertise: Light fabrication, Microfabrication, Electronics, Hardware control, Software Development, Cloud Computing, UHV and cryogenic tech, FPGA and RFSoC
