Quantum Computing Companies
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…
