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 towards 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 working towards building a “fault tolerant” quantum computer (accepting errors and working around them) based on cat qubits. Alice&Bob believes its first “useful” quantum computer will be available by 2030. “From the get go, Alice & Bob had a very clear vision of how quantum computers should be made [and] it was all about fault tolerance,” said CEO and co-founder Théau Peronnin in an interview. “What we’ve seen in the whole industry over the last 12 to 18 months is really a complete shift to align with our vision.” The appetite for more computing power is at the highest it has ever been — a belief underscored by major projects like the $500 billion Stargate AI data center commitment in the U.S., and the huge boost that computing chip makers like Nvidia have seen in recent times.
