Alice & Bob Enable Companies to Prepare for Practical Quantum Computing with Industry-First Logical Qubit Emulator

Alice & Bob publishes theoretical evidences that using cats you would need 60 times fewer qubits to run powerful quantum algorithms compared to other state-of-the-art architectures. In the lab, the first operations between qubits are performed on the Hydrogen chip series.

Dec 4, 2024 · The white paper outlines a clear path to achieving useful quantum computing through Alice & Bob’s cat qubit technology, which promises to deliver high-fidelity logical qubits while using significantly fewer hardware and energy …

How will we make it happen? Alice & Bob's detailed plan to build a useful quantum computer by 2030.

May 15, 2024 · If proven and scaled, it would enable industry-changing applications in chemistry, biotechnology, cryptography, and other fields. This chip demonstrates a cornerstone of Alice & Bob’s approach to fault-tolerant quantum computing: embedding bit-flip correction in each qubit.

We're harnessing reality's quantum nature. This is the science behind quantum computing ─ qubits, quantum errors and new kind of error correction.

Experimentalists validate our scientific progress toward fault-tolerance. With each iteration, we gain new insights, aiming for every chip produced and measured to be Alice & Bob’s best yet.

This roadmap outlines five key milestones that will bring us closer to achieving the first fault-tolerant quantum computer capable of solving real-world problems. The Five Key Milestones. Master the Cat Qubit; Build a Logical Qubit; Fault-Tolerant Quantum Computing; Universal Quantum Computing; Useful Quantum Computing
