IonQ to Acquire Oxford Ionics for $1.075 Billion to Accelerate Fault-Tolerant Quantum Computing

By combining IonQ’s hardware and software stack with Oxford Ionics’ ion-trap-on-chip technology, the deal outlines a roadmap to systems with two million physical qubits by 2030.

Overview

  • The acquisition consists of $1.065 billion in IonQ common stock and $10 million in cash and is expected to close in the second half of 2025.
  • The merged entity will target quantum systems with 256 physical qubits by 2026, more than 10,000 qubits by 2027, and two million qubits by 2030 at logical accuracies above 99.99%.
  • Oxford Ionics founders Dr. Chris Ballance and Dr. Tom Harty are set to remain with IonQ and lead expansion of its quantum development hub in Oxford.
  • Both companies were selected for DARPA’s Quantum Benchmarking Initiative earlier this year, underscoring their role in advancing fault-tolerant architectures.
  • IonQ’s collaborations with AstraZeneca, Amazon Web Services, and Nvidia demonstrated a hybrid quantum-classical workflow that cut a key drug discovery simulation from months to days.
