Alice & Bob has extended its Series B funding round to €100 million with new investment from NVentures, the venture capital arm of NVIDIA, signaling strong confidence in the pursuit of practical quantum computing. This expansion builds on prior backing from Future French Champions, AVP, and Bpifrance, and underscores the potential of Alice & Bob’s unique technology. The companies have already established a substantial technical collaboration, integrating Alice & Bob’s qubits with NVIDIA technologies like CUDA-Q, cuQuantum, and Dynamiqs. “We’ve been working alongside NVIDIA to connect our cat-qubit architecture with its full accelerated computing ecosystem,” says Théau Peronnin, CEO of Alice & Bob, adding that the investment “reinforces our common view that the future of quantum will be hybrid, combining quantum and classical computing to solve real-world problems.”
NVentures Extends Series B for Fault-Tolerant Quantum Computing
Alice & Bob specializes in “cat qubits,” a proprietary technology developed by its founders, and recently demonstrated a potential reduction in hardware requirements for large-scale quantum computing by up to 200 times compared to alternative methods. The investment is not simply financial; a pre-existing technical collaboration between Alice & Bob and NVIDIA has been deepening, with integration work already underway utilizing NVIDIA’s CUDA-Q, cuQuantum, and Dynamiqs platforms. This collaboration aims to integrate cat qubits with NVIDIA’s accelerated computing infrastructure and software, bringing quantum computers to high-performance computing centers globally. NVIDIA views this partnership as crucial for developing hybrid quantum-GPU supercomputers.
Cat-Qubit Architecture Reduces Hardware Requirements for Scalability
Alice & Bob’s advancements in cat-qubit technology are reshaping the projected scale of practical quantum computers, potentially circumventing a major obstacle to widespread adoption. Recent demonstrations reveal their architecture can reduce the hardware needed for a functional, large-scale quantum computer by as much as 200 times when contrasted with alternative qubit designs, and this efficiency stems from the unique properties of “cat qubits” developed by the company’s founders. This reduction in hardware demands is particularly significant given the escalating costs and complexity associated with building and maintaining quantum processors, which currently require extensive infrastructure for error correction. The company’s progress has attracted further investment, with NVentures, NVIDIA’s venture capital arm, extending Alice & Bob’s Series B round to €100 million, signaling strong investor confidence in the potential of fault-tolerant quantum computing despite the field’s early stage. Timothy Costa, Vice President and General Manager of Quantum at NVIDIA, affirmed that “Alice & Bob shares NVIDIA’s vision for accelerated quantum supercomputing,” and that ongoing integration projects are underway to deploy these cat-qubits within high-performance computing centers globally.
We’ve been working alongside NVIDIA to connect our cat-qubit architecture with its full accelerated computing ecosystem, from hardware to software, in support of the first fault-tolerant quantum computers.
