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 [...]

Equinix, a global digital infrastructure company, has announced a strategic partnership with Alice & Bob, a leading quantum computing company. This collaboration aims to provide Equinix customers worldwide, including in the United States, with secure access to Alice & Bob's advanced quantum technology through Equinix Metal and Equinix Fabric. Additionally, businesses can leverage Alice & Bob's quantum strategy services to unlock potential opportunities in areas such as simulation, optimization, machine learning, and cryptography. Alice & Bob's quantum technology features a patented self-correcting superconducting quantum bit called the cat qubit. This innovation addresses computation errors in current quantum computers, offering a more [...]

Rigetti Computing has appointed Thomas J. Iannotti as their new Chairman of the Board. He is also currently the Chairman of the Board of Directors at Applied Materials Inc. Mr. Iannotti has extensive experience in the computing industry and had served as the Senior Vice President and General Manager, Enterprise Services, at Hewlett-Packard Company before his retirements from that company. Earlier in his career, he had worked at Digital Equipment Corporation and Compaq Computer. Mr. Iannotti's predecessor, Cathy McCarthy, will continue to serve on the Rigetti Board of Directors. A press release announcing his appointment is available here. As part of [...]

Quantum Machines has announced it is create a new subsidiary in Germany called QM Technologies GmbH and is setting the subsidiary's headquarters in Stuttgart, Germany. There is a large amount of quantum activity in Germany and this new subsidiary will help the company access and participate in these projects. This will be Quantum Machines second European hub joining one in Denmark that they obtained in March 2022 when they acquired QDevil. In addition, the company has local teams in US, Canada, France, Japan, and Australia. A press release from Quantum Machines announcing the opening of this new German headquarters can be accessed here. Alice & [...]
