Q-Factor
Israeli neutral-atom quantum-computing startup spun out of the Weizmann Institute and Technion atomic-physics groups, emerged from stealth in April 2026 with a USD 24M seed round co-led by NFX and TPY Capital, with Intel Capital, Korea Investment Partners, and the Israel Innovation Authority participating. Pursues a Rydberg-interaction architecture with a stated long-term scaling target beyond one million qubits. Pre-product as of mid-2026, with first-generation high-qubit testbeds under assembly. Founded by Nir Davidson, Ofer Firstenberg, Yoav Sagi, and Guy Raz.

modalities.qc.qubit_type— Confirmed as neutral-atom Rydberg-interaction architecture; specific atomic species (Rb / Cs / Sr) not disclosed in launch materials -
founded— Calcalist reports founding in 2026; "months after its founding" framing in launch coverage suggests incorporation in late 2025 or early 2026 — exact registration date not public -
current_flagship.name— No named system; first-generation testbeds described as under assembly -
shareholders— Stake percentages not disclosed; private seed round with no public cap table -
key_personnel— No CEO publicly named in launch coverage; Guy Raz is the sole non-academic co-founder and the likely operating lead, but the title has not been confirmed -
roadmap— Million-qubit target is the stated long-term ambition without a dated milestone schedule
