Alice & Bob

We are working with superconducting circuits which is one of the most promising platforms for building a quantum computer. Our unique technology of self-correcting superconducting quantum bit, the cat qubit, allows for a much simpler road to fault-tolerant and universal gate-based quantum computing.
