Quantum Computing Companies
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…

Quantum Computing Inc
Quantum Computing Inc. (QCI) is a young entrant in the quantum computing race that has charted a strikingly different course from its larger rivals. Rather than building superconducting or ion-trap processors requiring extreme isolation, QCI focuses on photonic quantum machines that operate at room temperature and even embrace environmental noise - a paradigm it calls Entropy Quantum Computing. In theory, this approach allows QCI’s devices…

Xanadu
Xanadu is a Toronto-based quantum computing company pioneering photonic (light-based) quantum processors. Founded in 2016 by CEO Christian Weedbrook, the venture has quickly become a leader in continuous-variable photonic quantum computing hardware and software. Xanadu’s approach leverages squeezed-light photons as qubits - allowing operations at room temperature and compatibility with existing fiber-optic networks - in contrast to the cryogenic setups required by superconducting or trapped-ion…
