Quantum Leap: Alice and Bob Achieve 10x Qubit Stability Increase

French quantum qubit developer Alice and Bob have made significant advancements in extending the stability of qubits for quantum computers. Their latest research has shown a remarkable increase in the resilience of qubits, particularly in reducing quantum errors.

The Cat qubit design developed by Alice & Bob has proven to extend the resilience to quantum errors, with bit-flip times now exceeding tens of seconds. This breakthrough research, conducted in collaboration with the Quantic team in Paris, marks a crucial milestone in the field of quantum computing.

The study titled "Quantum control of a cat-qubit with bit-flip times exceeding ten seconds" showcases the substantial improvement in the stability of superconducting qubits, paving the way for more reliable and fault-tolerant quantum computing systems.

By significantly extending the bit-flip times from milliseconds to tens of seconds, Alice & Bob have achieved a level of performance that surpasses any other existing superconducting qubit technology. This advancement holds great promise for the future of quantum computing.

In a recent development, Alice & Bob have successfully taped out a 16-qubit quantum processor, demonstrating their commitment to pushing the boundaries of quantum technology and expanding the capabilities of quantum computing systems.

Quantum computers are susceptible to two main types of errors: bit-flips and phase-flips. The innovative Cat qubit design by Alice & Bob has been instrumental in exponentially reducing bit-flips, which are akin to classical bit flips in traditional digital computing.

"This successful collaboration has leveraged our cat qubit design to achieve remarkably long bit-flip times while maintaining precise quantum control," stated Raphaël Lescanne, the CTO of Alice & Bob. The team's dedication to overcoming the challenges of quantum error correction is evident in their groundbreaking research.

Utilizing their 'Boson 3' chipset, which features the TomCat cat qubit design, Alice & Bob have set a new standard in quantum computing. The efficient quantum tomography protocol employed in TomCat allows for enhanced control of quantum states without the need for a transmon, a common source of bit-flips in other quantum systems.

The Boson 4 chipset, another remarkable achievement by Alice & Bob, has achieved over 7 minutes of bit-flip lifetime, showcasing the scalability and reliability of their quantum technology.

Looking ahead, Alice & Bob are focused on further enhancing their technology to meet the demands of their latest architecture, aiming to deliver a 100 logical qubit quantum computer. Their ongoing efforts to improve cat qubit phase-flip times and readout fidelity underscore their commitment to innovation in quantum computing.

The team's ability to control the phase of coherent superpositions while achieving macroscopic bit-flip times represents a significant step towards developing fully protected hardware-efficient quantum architectures.

With a system that inherently stabilizes against bit-flips, Alice & Bob are pioneering more efficient quantum error correction methods that address phase-flips with greater precision. This strategic approach is poised to revolutionize the field of quantum computing.

"Alice & Bob is dedicated to advancing the stability of cat qubits and refining quantum error correction techniques," affirmed Théau Peronnin, the CEO of Alice & Bob. Their research underscores the unparalleled potential of prolonged bit-flip times offered by their superconducting qubit technology.
