Questions

Can a foreigner apply for these roles?

36 of the 36 roles here state no citizenship or security-check demand. A role that does - export-controlled quantum hardware and cryptography work often does - says so in its advert, and the card marks it.

Which quantum companies hire most?

QunaSys (8), QuEra Computing (7), Nanofiber Quantum Technologies (5), JIJ (5), Quantinuum (3).

Which employers count as quantum companies?

Companies whose main business is quantum technology - quantum computer makers (superconducting, trapped-ion, neutral-atom, photonic, spin qubits), quantum software and algorithm companies, quantum sensing and communication, and the makers of their control electronics, lasers and cryogenics - and every role whose title names quantum work at any employer.

How fresh is this?

Every role is re-checked on the employer's own careers board at least every 48 hours, and the page is rebuilt every night.
