🚀 IonQ Tempo Timeline & Key Milestones

2024
   •   Late 2024: IonQ began ramping production of Forte Enterprise systems. Reddit commentary suggests a plan to build five units—with production shifting to Tempo after these are complete. ?
   •   July 22, 2024: IonQ presented its accelerated roadmap, setting Tempo as a 2025 delivery goal, emphasizing high performance, error correction features, and enterprise readiness. ?

Early 2025
   •   January 10, 2025: CEO Peter Chapman reaffirmed Tempo (AQ?64) is set for 2025 delivery, alongside next-gen AQ?256 systems. ?
   •   IonQ targets >99.9% physical two-qubit gate fidelity on Tempo and 99.999% logical gate fidelity by year-end 2025 using their new partial error-correction technique. ?
   •   Tempo is the first to use barium-based qubits and a reconfigurable multi-core quantum architecture (RMQA), enabling scalability and faster gate operations. ?

2025 (Delivery Year)
   •   Tempo is expected to ship development systems with AQ?64, supporting 100 physical qubits and flexible mid-circuit measurement capabilities. ?
   •   IonQ projects achieving 99.999% logical fidelity by the end of 2025. ?

Beyond Tempo
   •   By 2027: IonQ aims for 10,000 physical qubits on a single chip. ?
   •   2028: A multi-chip photonically interconnected system targeting 20,000 physical qubits and full quantum networking. ()

🎯 Why Tempo Matters
   •   Enterprise-Grade Design: Rack-mountable, modular architecture engineered for enterprise data centers—not lab environments. ()
   •   Error Correction Breakthroughs: IonQ’s 3:1 physical-to-logical qubit ratio significantly advances mid-circuit error correction, targeting fault tolerance sooner. ?
   •   Barium Qubits & RMQA: This new material system and multi-core approach support scalability, throughput, and resilience. ?

?

✅ Key Takeaways
   •   Tempo is set for 2025 delivery, transitioning IonQ into production-ready, enterprise-grade quantum hardware.
   •   It will launch with AQ?64, supporting ~100 physical qubits, with fidelity optimized for real-world workloads.
   •   This system represents a major leap in IonQ’s roadmap, unlocking scalable performance and setting the stage for 10k–20k qubit systems by 2027–2028, and eventually reaching 2 million physical qubits by 2030. ? ?
