Alice & Bob brings fault-tolerant Boson cat qubit quantum chip to Google Cloud Market

French quantum computing startup Alice & Bob as we speak introduced that its first cat qubit quantum chip in its “Boson” collection is now accessible on the Google Cloud Market, giving Google clients entry to fault-tolerant quantum computing.

Named after the Schrödinger’s cat thought experiment, cat qubits are a kind of superconducting qubits developed by Alice & Bob to make quantum computer systems extra strong and immune to errors. Cat qubits tackle the difficulty the place conventional qubits, which might be in a state of 0, 1 or a “superposition” of each, are delicate to their atmosphere. Any disturbance could cause a qubit to “decohere” and lose its superposition state, resulting in computational errors.

Cat qubits tackle decoherence by being designed to be “error-protected” by means of error correction that shops quantum info throughout many particles, making them extra resilient to environmental disturbances. Alice & Bob’s cat qubits additionally embrace a hardware-efficient design that reduces the {hardware} necessities for a fault.

The brand new Boson 4 chip accessible by means of Google Cloud as we speak extends the bit-flip time, the length a qubit can preserve its state earlier than it experiences a bit-flip error, to seven minutes. This contrasts with typical superconducting quantum computer systems, the place bit-flip errors can happen dozens of occasions per second, even in one of the best instances.

The startup says the chip represents 4 orders of magnitude enchancment over state-of-the-art superconducting qubits. The development signifies that qubits can preserve their state with out experiencing a bit-flip error for a for much longer length. That’s essential for creating extra secure and fault-tolerant quantum methods and attaining sensible and scalable quantum computing.

With the Boson 4 chip now accessible by means of the Google Cloud Market, Alice & Bob says the scientific neighborhood can now confirm the advantages and potential of cat qubits by performing its personal experiments.

“When my co-founder and I began Alice & Bob, many thought cat qubits would by no means be greater than a lab idea,” stated Chief Government Théau Peronnin. “We at the moment are the primary firm to make a cat qubit chip accessible for everybody to make use of. We’re satisfied Boson 4 will spark curiosity amongst researchers and we’re dedicated to repeatedly extending the vary of experiments which might be carried out with it.”

Alice & Bob is a enterprise capital-backed startup, having raised about $33 million in funding. Traders embrace Elaia Companions SAS, Banque publique d’investissement, Supernova Make investments SAS and Breega Capital SAS.
