Google DeepMind has come up with an error correction technique it says will make quantum computers more reliable, particularly at scale. While quantum computing holds tremendous promise — potentially able to solve in just a few hours problems it would take a conventional computer “billions of years” to figure out, Google claims — the systems are notoriously unstable, due to the delicacy of the “quantum state.” AlphaQubit is an AI-based decoder that identifies quantum computing errors with accuracy. Combining DeepMind’s machine learning expertise with Google Quantum AI error correction, the technique advances efforts to create a reliable quantum computer.

CuspAI, a UK startup that aims to help engineer sustainable materials, has raised $30 million from venture funds in Europe and the U.S., secured a partnership with Meta’s FAIR unit, and employed the advisory services of AI pioneer Geoffrey Hinton in its mission to tackle climate change. “CuspAI leverages cutting-edge generative AI, deep learning, and molecular simulation to streamline the material design process,” the company announced. Its platform “functions like a search engine for materials, allowing users to request specific properties for new materials on demand,” speeding the process of “the discovery of materials with precise functionalities.” Continue reading Green Startup CuspAI Secures $30 Million, Meta Partnership

Microsoft and Quantinuum have improved the logical error rate in quantum computing by 800x, a breakthrough the partners say has the potential to usher in a new era of qubit processing. Using ion-trap hardware from Quantinuum and a qubit-virtualization system from Microsoft, the team ran more than 14,000 experiments with no errors — a huge feat in the notoriously fickle realm of qubits. The system has error diagnostics and corrections built in, identifying which errors need to be fixed and correcting them without destroying the underlying logical qubits, according to the companies.
