IonQ Announces Agreement to Acquire Oxford Ionics, Accelerating Path to Pioneering Breakthroughs in Quantum Computing
Deal builds on the strategic cooperation between
Combined entity intends to deliver the world’s most powerful quantum computers by bringing together complementary technologies
The combination is expected to accelerate innovation in drug discovery, materials science, financial modeling, logistics, chemistry, aerospace, cybersecurity and defense

IonQ is a leader in quantum computing and networking, developing high performance systems based on trapped ion technology, to help solve the world’s most complex commercial and research challenges. Oxford Ionics holds the current world records for fidelity, which measures the accuracy of quantum operations.
The transaction will bring together IonQ’s quantum compute, application and networking stack with Oxford Ionics’ groundbreaking ion-trap technology manufactured on standard semiconductor chips. The combined technologies are expected to deliver innovative, reliable quantum computers that increase in power, scale, and problem-solving capabilities. Both companies expect to benefit from the other’s complementary technologies, deep expertise, and IonQ’s global resources and established customer base.

“IonQ’s vision has always been to drive real-world impact in every era and year of quantum computing’s growth. Today’s announcement of our intention to acquire Oxford Ionics accelerates our mission to full fault-tolerant quantum computers with 2 million physical qubits and 80,000 logical qubits by 2030,” said Niccolo de Masi, CEO of IonQ. “We believe the advantages of our combined technologies will set a new standard within quantum computing and deliver superior value for our customers through market-leading enterprise applications.
De Masi continued, “We are pleased to welcome Oxford Ionics founders Dr. Chris Ballance and Dr. Tom Harty, and the rest of the Oxford Ionics team to IonQ. Their groundbreaking ion-trap-on-a-chip technology will accelerate IonQ’s commercial quantum computer miniaturization and global delivery. Our combined path to millions of qubits by 2030 will help ensure unit economics, scale, and power as quantum computing rapidly evolves.”
“We're tremendously excited to work alongside the world-class quantum computing and networking teams at IonQ. Together, we intend to move faster than any other player in the industry to deliver the leading fault-tolerant quantum computers with transformative value for customers,” said CEO of Oxford Ionics, Dr. Chris Ballance. “At Oxford Ionics, we have not only pioneered the most accurate quantum platform on the market – we have also engineered a quantum chip capable of being manufactured in standard semiconductor fabs. We look forward to integrating this innovative technology to help accelerate IonQ’s quantum computing roadmap for customers in
The acquisition of Oxford Ionics follows IonQ’s recent quantum computing and networking momentum, including the recent acquisition of Lightsynq and pending acquisition of Capella.
