Twenty companies, six ways to build a quantum computer: Israel’s quantum map

In 2019, Israel had five quantum companies and about 50 people working in the field.

Last July, a private-sector map of the field counted nine core quantum computing startups, along with about 15 working on related technologies.

But there is no consensus on how to build a quantum bit, or qubit, the basic unit of quantum information.

Q-Factor is pursuing neutral atoms, Quantum Source is focused on photonic quantum computing, LightSolver works on optical computing, and Quantum Transistors is developing a diamond-based quantum chip.

It also operates the Israeli Quantum Computing Center at Tel Aviv University.
