Tiny French chip startup challenges mighty Amazon to produce formidable quantum chip – inspired by a famous cat

Quantum computers have shown amazing promise in recent years, with companies from IBM to Google building increasingly powerful machines that are expected to many areas fundamentally, from encryption to medical research.

Quibits – quantum bits that occupy a superposition of both 1 and 0 at the same time – are the building blocks of quantum machines. But today’s most powerful quantum computers are hugely inefficient due to a phenomenon called ‘quantum error’. This affects more than 1,000 qubits for every single unaffected ‘logical’ quibit.
