Corporate
Alice & Bob operates from dual headquarters in Paris, France and Cambridge, Massachusetts, representing the pioneering quantum computing company developing the world's first universal fault-tolerant quantum computer exclusively based on cat qubit technology. The Boston headquarters is located at 1 Broadway Building, Cambridge, Massachusetts, strategically positioned in the heart of the Cambridge academic and commercial landscape renowned for quantum research excellence. The Paris headquarters serves as the primary corporate center with plans for a new 4,000 square meter state-of-the-art research and development facility currently under construction to house advanced quantum chip development operations. Founded in 2020 by CEO Théau Peronnin (t******@alice-bob.com) and CTO Raphaël Lescanne, the company has raised €130 million total funding including a €100 million Series B round led by Future French Champions, AVP (AXA Venture Partners), and Bpifrance in January 2025. The workforce has expanded to 110 employees including over 30 PhDs with plans to reach 200 personnel during the current funding phase, maintaining selective recruitment from leading European academic institutions. Alice & Bob achieved historic recognition as the first quantum computing company selected for France's prestigious French Tech Next40 program in June 2025, placing the company within a national framework supporting high-growth technology firms with proven commercial traction. The company is constructing a $50 million quantum chip development lab in Paris featuring state-of-the-art cleanroom facilities, 20 cryostats, and integrated quantum systems, while also receiving €16.5 million in French government funding through the "Cat Factory" project to advance fault-tolerant quantum computing architecture.

Market
The quantum error correction market represents over 90% of quantum computing's ultimate value proposition, currently valued at $1.8 billion with projections reaching $15.2 billion by 2030 representing a 41.3% compound annual growth rate as fault-tolerant quantum computers transition from research to commercial applications. The superconducting quantum processor segment within this market commands $680 million current market size with 38.7% CAGR driven by major technology companies' adoption of quantum cloud services and enterprise customers seeking practical quantum advantage for optimization and simulation workloads. The fault-tolerant quantum computing subsegment specifically represents $420 million in 2025 market value with extraordinary 67.2% growth rate as industry consensus shifts away from NISQ (Noisy Intermediate-Scale Quantum) approaches toward error-corrected logical qubit systems. Error correction hardware and software integration markets total $290 million presently with 45.8% annual expansion as quantum companies recognize that hardware-level error suppression provides superior resource efficiency compared to software-only error correction approaches. European quantum computing investment reached €820 million across startups while French quantum companies specifically attracted €370 million, demonstrating strong regional market development and government support for quantum technology commercialization. The logical qubit achievement market represents the critical inflection point where quantum computing transitions from experimental to practical utility, with early market entrants capturing disproportionate value through intellectual property advantages and customer relationships.
Product
Alice & Bob's core product portfolio centers on cat qubit quantum processing units featuring built-in hardware-level error correction that reduces quantum error correction from a two-dimensional surface code problem requiring ~1,000 physical qubits per logical qubit to a one-dimensional repetition code needing as few as 5 physical cat qubits per logical qubit. The current Boson chip series achieved Milestone 1 with reliable cat qubit manufacturing and world-record bit-flip protection exceeding seven minutes, while the upcoming Helium series targets Milestone 2 with the company's first error-corrected logical qubit operating below the error-correction threshold. Advanced LDPC (Low-Density Parity-Check) cat codes enable 100 high-fidelity logical qubits operation with only 1,500 physical cat qubits, compared to conventional approaches requiring 20 million physical qubits for equivalent functionality, representing 200-fold resource efficiency improvement. Revolutionary "squeezed" cat qubits demonstrate 160x improvement in bit-flip error rates through quantum state compression techniques that optimize error suppression without increasing phase-flip errors, extending bit-flip lifetimes from 138 milliseconds to over 22 seconds. The product ecosystem includes NVIDIA CUDA-Q integration through Dynamiqs simulation library providing 75x speedups for time-dependent quantum system simulation on GPUs, enabling researchers and developers to model cat qubit behavior efficiently. Cloud accessibility through "The Box" platform allows global testing of cat qubit technology, democratizing access to revolutionary quantum error correction capabilities for research institutions and commercial developers. Platform competition includes IBM's transmon-based quantum processors, Google's Sycamore superconducting qubits, Rigetti's Aspen series, IonQ's trapped-ion systems, while pure-play competition encompasses Quantum Circuits Inc's dual-rail cavity approach, Atlantic Quantum's fluxonium architecture, Oxford Quantum Circuits' coaxmon designs, and emerging players like Anyon Systems' on-premise solutions.
The cat qubit architecture addresses the breadth of quantum computing market requirements by providing the fundamental building block for fault-tolerant quantum computers with dramatically reduced overhead compared to conventional approaches. The technology enables practical implementation of quantum algorithms like Shor's factoring algorithm with 60-200 times fewer qubits than competing architectures, making quantum cryptography breaking economically feasible with hundreds of thousands rather than tens of millions of physical qubits. Alice & Bob's fault-tolerant approach accepts some errors while fixing others at the hardware level, distinguishing it from competitors who attempt to correct all errors through software-based error correction requiring massive qubit overhead. Research and development moats include proprietary cat state stabilization mechanisms protecting against bit-flip errors, advanced control systems optimizing quantum gate fidelity, scalable manufacturing processes enabling cost-effective cat qubit production, and theoretical frameworks for LDPC error correction on cat qubit architectures. The company's 35% R&D allocation to Cat Qubit Architecture creates defensive patent barriers around fundamental superconducting circuit designs, while 25% investment in Error Correction Hardware develops hardware-level fault tolerance mechanisms that competitors cannot easily replicate. The "Cat Factory" government collaboration targeting 2.5x reduction in control complexity demonstrates ongoing innovation in practical quantum computer engineering rather than purely theoretical advances.
