Alice & Bob and Inria Detail “Unfolded Code” for Hardware-Efficient Magic State Preparation

Mohamed Abdel-Kareem2025-08-06T07:06:44-07:00

Scientists from Alice & Bob, a quantum computing company, and Inria, France’s national institute for research in digital science and technology, have submitted a new study for peer review. The study details a new quantum error correction scheme, dubbed the “unfolded code,” which presents a method for producing magic states on superconducting quantum computers. This research addresses the challenge of magic state preparation, a resource-intensive aspect of quantum computing necessary for achieving a universal fault-tolerant gate set. Their new approach, outlined in the paper “Unfolded distillation: very low-cost magic state preparation for biased-noise qubits,” leverages the noise bias of cat qubits, [...]

Alice & Bob Raises €100M ($104.9M USD) Series B to Accelerate Cat Qubit-Based Fault-Tolerant Quantum Computing

Mohamed Abdel-Kareem2025-01-28T12:01:01-08:00

Alice & Bob, a company developing fault-tolerant quantum computers, announced the closure of a €100 million ($104.9 million USD) Series B funding round, led by Future French Champions (FFC), AVP, and Bpifrance. The funding aims to advance Alice & Bob’s mission of building the world’s first useful quantum computer by 2030. Alice & Bob’s proprietary “cat qubit” technology suppresses bit-flip errors, enabling scalable quantum computing with significantly reduced hardware requirements. This innovation allows the company to achieve fault tolerance with only thousands of qubits instead of the millions needed by other approaches. Funds will support the development of the first error-corrected [...]
