Alice & Bob is a quantum computing company based in Paris and Boston.[1][2] The company is known for its cat qubit quantum architecture and its work in quantum error correction.[1][3]
Alice & Bob was spun out of a federation of French research labs by Théau Peronnin and Raphaël Lescanne.[4] While pursuing his PhD in physics, Peronnin was part of the quantum-electronics group at École normale supérieure, building the academic foundations for quantum computers. Meanwhile, Lescanne published a paper on exponential suppression of bit-flips in a qubit encoded in an oscillator.[5] Together, Peronnin and Lescanne co-founded Alice & Bob in 2020 to continue this work.[6][7]
Since then, the company has raised more than $134 million in funding to develop fault-tolerant quantum computers based on cat qubits.[1][8]
In 2023, Alice & Bob opened a subsidiary in Boston to facilitate the company's expansion.[9]
The following year, the company was selected for France's $548 million PROQCIMA initiative, a key component of the nation’s National Strategy for Quantum.[10]
In 2025, Alice & Bob announced plans to build a $50 million advanced quantum computing laboratory in Paris to support product development and testing.[11]
Later that year, DARPA selected the company to join its Quantum Benchmarking initiative, a project focused on identifying which approaches can deliver an industrially useful quantum computer. [12]
