The unique ability of qubits to exist in multiple states concurrently leads to exponentially faster calculations, making quantum computers particularly valuable for industries where data processing speed and accuracy are critical.
Fault-Tolerant Quantum Computers
Alice & Bob’s approach centers around an innovative concept known as “cat qubit” quantum architecture. The company’s vision is notably clear: achieving fault tolerance is key to making quantum computers viable. According to CEO and co-founder Théau Peronnin, the quantum computing industry has seen a significant shift aligning with this vision over the past year to year and a half. The quest for a fault-tolerant quantum computer—one that can effectively handle and rectify errors during computations—is crucial for the scalability and practical deployment of quantum systems.
The “cat qubit” architecture is inspired by Schrödinger’s cat, a famous thought experiment in quantum mechanics that illustrates the principle of superposition. This architecture focuses on a holistic design that incorporates error correction directly into the hardware, rather than increasing the number of qubits in an attempt to eliminate all faults. By accepting that some errors are inevitable and designing systems to manage and correct these errors, Alice & Bob aim to simplify the overall system architecture. This strategy is not merely theoretical; it has positioned the startup to potentially have a functional and scalable fault-tolerant quantum computer by 2030. This innovative approach is gaining traction within the industry, signaling a move towards more practical and accessible quantum computing solutions.
