Quantum Computing Companies
Quantum Art
Quantum Art is an Israeli quantum computing startup (spun out of the Weizmann Institute of Science in 2022) focused on developing scalable trapped-ion hardware for quantum computers. The company was born out of decades of ion-trap research at Weizmann and the achievement of Israel’s first full-stack quantum computer by its founding team. Led by a team of ~40 physicists and engineers, including veterans from academia…

Quantum Brilliance
Quantum Brilliance (QB) is an Australian-German quantum computing company (founded in 2019 as a spin-out of Australian National University) developing diamond-based quantum accelerators that operate at room temperature. Their hardware uses nitrogen-vacancy (NV) centers in synthetic diamond as qubits - defects in a diamond lattice where a nitrogen atom sits adjacent to a missing carbon. NV-center qubits are attractive because diamond’s rigid lattice protects the…

Quantum Circuits Inc (QCI)
Quantum Circuits, Inc. (QCI) is a Yale University spin-out that has pioneered a novel approach to superconducting quantum computing focused on hardware-efficient error correction. Co-founded in 2017 by leading Yale physicists (including Robert Schoelkopf, Michel Devoret, and Luigi Frunzio), QCI’s mission is to accelerate the path to fault-tolerant quantum computers by "correcting first, then scaling". Unlike many competitors in the superconducting qubit arena that emphasize…

QuiX Quantum
QuiX Quantum is a Dutch quantum technology company specializing in photonic quantum computing hardware. Founded in 2019 as a University of Twente spin-off, QuiX has quickly grown into a European leader in photonic quantum processors and systems. Unlike matter-based qubit platforms that use stationary quantum bits on a cryogenic chip, QuiX’s approach encodes qubits in photons - particles of light that serve as “flying” qubits…

Oxford Ionics
Oxford Ionics is a UK-based quantum computing company specializing in trapped-ion technology, distinguished by its use of microwave-based “electronic” quantum gates instead of the laser-based control typical of most ion-trap systems. Co-founded in 2019 by Dr. Chris Ballance and Dr. Tom Harty - both leading ion-trap researchers - the company has rapidly built a reputation for record-setting performance in qubit fidelity. Oxford Ionics integrates all…

Quandela
Quandela is a French quantum computing company founded in 2017 as a spin-off from the Centre for Nanoscience and Nanotechnology (C2N) in Paris. It has established itself as a pioneer in photonic quantum computing, focusing on single-photon-based qubits and integrated photonic circuits. Quandela’s core modality is optical (photonic) quantum computing, leveraging single photons as qubits. This approach differentiates it from superconducting or trapped-ion platforms, enabling…

Planqc
Planqc is a Munich-based quantum computing startup (founded in 2022 as a Max-Planck-Institute spin-off) developing a neutral-atom quantum computing platform. The company’s core approach is to store quantum information in individual ultra-cold atoms that are trapped in optical lattices - effectively using nature’s identical atoms as qubits. By leveraging techniques from atomic clocks, high-resolution quantum gas microscopes, and fast Rydberg-mediated gates, planqc aims to build…

Quantinuum
Quantinuum, formed by the 2021 merger of Honeywell Quantum Solutions and Cambridge Quantum, is another leader in trapped-ion quantum computing. It combines Honeywell’s hardware prowess with Cambridge’s algorithm/software expertise. Quantinuum’s roadmap is notably direct about pursuing fault tolerance, and they’ve recently accelerated their timeline.
