Qolab is a quantum hardware company building scalable superconducting quantum processing units using semiconductor manufacturing techniques. It was founded in 2022 by Alan Ho (former Head of Product for Google Quantum AI), John Martinis (former Head of Hardware for Google Quantum AI and 2025 Nobel laureate in Physics) and UW-Madison physics professor Robert McDermott, and incubated at the University of Wisconsin-Madison. The company fabricates its own qubits and sells a turn-key superconducting QPU platform to research institutions while working toward utility-scale machines. It raised a $16M Series A led by Octave Ventures with the Development Bank of Japan, WARF and Phoenix Venture Partners, and has since announced manufacturing collaborations with partners including Applied Ventures.
What sets it apart
A window-junction fabrication process that replaces lift-off with subtractive etching on 300mm semiconductor tools, plus wafer-scale integration of qubit and wiring wafers into modular tiles, aimed at making high-coherence qubits manufacturable at scale rather than one chip at a time.
A deployable superconducting quantum processing unit platform with a turn-key experimental setup, high-quality in-house fabricated qubits and pulse-level hardware control, able to load up to six devices in a single cooldown for parallel research.
