Quantum computers are an incredible innovation. They use a concept called superposition to simulate several different solutions to a given problem at once, so they're more efficient than traditional computers at processing specific workloads, particularly in areas like science and cryptography. Rigetti Computing (RGTI 3.79%) has built some of the industry's most capable quantum computers, but they still produce relatively high error rates, making them impractical for solving many real-world problems. As a result, the company is struggling to generate meaningful revenue. Rigetti stock has plummeted 61% from last year's record high; here's where I predict it could be in 12 months. Rigetti's most powerful computer is now widely available Rigetti is unique because it built an entire in-house supply chain for its quantum computing business. It operates a fabrication facility, it created its own programming language called Quil, and it even launched its own cloud platform where it leases quantum computing capacity to enterprises for a fee. Therefore, Rigetti can bring new computers to market and commercialize them much faster than its competitors. During the first quarter of 2026, the company made its flagship Cepheus-1-108Q system widely available through its own cloud platform, but also through third-party platforms including Amazon Braket and Microsoft Azure Quantum, giving it unprecedented reach. NASDAQ: RGTI Key Data Points Cepheus-1-108Q is the industry's largest multichip quantum computer. It features 108 qubits, so it offers 3 times the scale of Rigetti's previous Cepheus-1-36Q system. It also boasts a single-qubit gate fidelity of 99.9%, which means it only makes one error in every 1,000 quantum operations. That error rate still makes Cepheus-1-108Q impractical for solving many real-world problems. Moreover, it has a 2-qubit fidelity of just 99.1%, implying nine errors for every 1,000 quantum operations. Qubits are extremely sensitive to noise, so making two of them
