Alice & Bob raises $104M, says quantum computers based on cat qubits will be ready by 2030

Quantum computing remains something of a holy grail in the world of technology: It promises a huge leap in computing power, but only if someone can figure out how to square away the fault rates that prevent any scaling of the tech.

Now, one of the more promising quantum startups in Europe is announcing a big round of funding to help it work toward a solution.

Alice & Bob, a Paris-based startup that is a pioneer in the area of cat qubit quantum architecture, has raised €100 million ($104 million). It plans to use this Series B to continue…
