Alice & Bob is a quantum computing company founded in 2020 with headquarters in Paris and Boston. The company specializes in pioneering cat qubits, a type of qubit with built-in error correction that significantly reduces hardware requirements for fault-tolerant quantum computers by up to 200 times compared to traditional approaches. Their mission is to build the first universal, fault-tolerant quantum computer capable of delivering meaningful results for real-world applications. Alice & Bob serves researchers, developers, and industries seeking to harness quantum computing power, offering cloud access to their cat qubit technology for experimentation. The company has demonstrated experimental results surpassing those of major tech giants like Google and IBM and has raised over €130 million in funding, growing rapidly with more than 150 employees[1][2][3][5][6].
Alice & Bob was co-founded in 2020 by Theau Peronnin (CEO) and Raphaël Lescanne (CTO), who brought together expertise in quantum physics and engineering. The idea emerged from their work on superconducting circuits and quantum error correction, focusing on cat qubits—a technology that inherently suppresses bit-flip errors, a major obstacle in quantum computing. Early traction included demonstrating superior experimental results and securing significant funding to accelerate development. The company has been advised by Nobel Prize-winning researchers and pioneers like Michel Devoret, who co-invented the cat qubit and contributed to Alice & Bob’s early development[1][3][4].
Alice & Bob is riding the wave of quantum computing’s transition from theoretical research to practical, fault-tolerant machines. The timing is critical as industries increasingly seek quantum advantage for complex problems in material science, cryptography, and optimization. Market forces such as growing investment in quantum technologies, advances in superconducting qubits, and the need for scalable error correction favor Alice & Bob’s cat qubit approach. By reducing hardware complexity and error rates, they influence the ecosystem by setting new standards for quantum computer design and enabling broader access through cloud platforms. Their work accelerates Europe’s position in the global quantum race, contributing to digital sovereignty and innovation[2][3][4][6].
Looking ahead, Alice & Bob aims to deliver the first utility-scale quantum computer for industrial applications by 2030. Their focus will be on optimizing error correction, building logical qubits, and scaling their technology. Trends shaping their journey include increasing demand for quantum advantage, advances in quantum hardware and software integration, and expanding quantum cloud services. As their influence grows, Alice & Bob is poised to be a cornerstone in the quantum computing ecosystem, driving innovation and enabling new computational capabilities across sectors. Their pioneering cat qubit technology and strong scientific foundation position them uniquely to transform quantum computing from experimental to practical use[3][5][6].
