A century after quantum mechanics revolutionised physics, one of its most transformative applications - the quantum computer - is edging closer to reality. Among the global race of companies pursuing this technology, French startup Quandela is taking a distinctive approach from its headquarters in Massy, just outside Paris.
The company has already built two quantum computers that use photons - particles of light, to encode and process information, setting it apart from competitors relying on other quantum computing architectures.
