The grant was provided by Bpifrance on behalf of the French government as part of the France 2030 initiative. Alice & Bob's partners in this effort include academic partners ENS de Lyon and Mines Paris - PSL. The project, named Cat Factory, will use Alice & Bob's Cat qubit technology which we recently described here which combines a base Cat qubit which virtually eliminates bit flips with an LDPC code to create a much more efficient implementation. To achieve 100 logical qubits, this projects intends to use just 1500 physical qubits that will be fitted into a large dilution refrigerator and [...]

Alice & Bob’s scientific leadership and advisors. Alice & Bob, a prominent developer in fault-tolerant quantum computers, has announced its newly constituted Consultative Board, comprising quantum computing pioneers Daniel Gottesman, David DiVincenzo, John Martinis, and Yasunobu Nakamura. The board will advise on the long-term roadmap and prioritization of milestones. Daniel Gottesman is renowned for the Gottesman-Knill Theorem, proving quantum error correction codes' utility in achieving fault-tolerant quantum computing. David DiVincenzo established the "DiVincenzo Criteria," defining quantum computers' minimal requirements. John Martinis led Google’s 2019 quantum supremacy experiment. Yasunobu Nakamura pioneered the superconducting qubit. Raphael Lescanne, CTO and Co-founder of Alice & [...]

A very important ratio for fault tolerant quantum computers is the Physical-to-Logical ratio. The represents the number of physical qubits needed to implement a logical qubit. The lower this ratio is, the better because it makes it easier to implement in hardware, reduces the cost of the machine, and many other things. The problem is that with many of the quantum error correction codes that have been developed, the number is quite high. It could be 1000:1 or even higher. One of the reasons quantum error correction is harder than classical error correction is that many quantum processors can suffer from [...]

The chip is codenamed Helium 1 and contains 16 qubits to test out Alice & Bob's cat qubit architecture for achieving a very high fidelity logical qubit. The term "tape out" means that the company has finished the design and sent the design files to a fabrication facility for construction. After the chip has been built, it will undergo extensive testing, characterization, and calibration by the company's engineering team to realize the optimum performance and then made available for external use by the company's customers. Any lessons learned during this process will be utilized in the design of the next chip [...]

Alice & Bob, a hardware developer in quantum computing, has partnered with OVHcloud to launch Felis, the first quantum emulator capable of predicting the behavior of logical qubits. Available through the OVHcloud Public Cloud universe, Felis allows users to tune error rates and abstracts error correction, simplifying quantum algorithm testing. Felis is a significant addition to OVHcloud’s quantum emulators and a step forward for the French quantum industry. It enables algorithm developers to experiment with high-quality qubits, accelerating the path to industrially relevant applications. This is the first time an emulator is capable of anticipating the behavior of logical qubits with [...]
