Gemini-Class Gate-Model Quantum Computer
A gate-model neutral-atom platform bringing programmable, logical qubit experiments into reach, today’s bridge to tomorrow’s quantum advantage.
Technical Highlights & Architecture
Highly Flexible
Dynamic qubit array (DQA™) shuttles qubits across two zones, storage and entanglement, for fault‑resilient mapping and flexibility.
All‑to‑All Connectivity
Native parallel entangling capabilities accelerate circuit execution over densely connected logic graphs.
High Performance
Delivers > 99 % fidelity on 1‑qubit gates and > 99.2 % on 2‑qubit gates, even across low‑latency parallel pairs. SPAM and shuttling fidelities also exceed 99 %.
Hybrid Ready
Designed for room temperature integration with HPC-class systems or use alongside analog platforms via Bloqade™ emulation.
Innovation Spotlight: Fault-Tolerant Breakthroughs on Gemini
Gemini isn’t just experimental: it’s foundational to fault-tolerant quantum progress.
In collaboration with Harvard and MIT, QuEra demonstrated logical‑level magic‑state distillation entirely within the logical qubit layer on Gemini, building error‑protected logical qubits using distance‑3 and distance‑5 color codes and a 5‑to‑1 distillation protocol.
This result achieved higher magic‑state fidelity than inputs, with quadratic suppression of logical errors, marking the first time fault‑tolerant magic state generation has been executed in practice.
