IonQ has appointed Inder M. Singh as its new CFO and COO, a dual-role leadership change aimed at accelerating the company’s growth and innovation.

On September 4, 2025 (local time), IonQ announced a strategic leadership change to accelerate corporate growth and innovation, appointing Inder M. Singh as Chief Financial Officer (CFO) and Chief Operating Officer (COO).
Simultaneously, the company officially announced a groundbreaking advancement in the development of synthetic diamond film, a core technology for quantum computing and networking.
According to reports from investors.ionq, Seeking Alpha, optics.org, PostQuantum, and Ainvest, the new CFO-COO Singh, 66, immediately succeeded former CFO Thomas Kramer, who will serve in an advisory role for up to 60 days to support the transition.
Singh’s appointment brings over 30 years of financial and strategic experience, including serving as a senior independent director on IonQ’s board and successfully leading Arm’s massive IPO in 2023 as its CFO.
Meanwhile, IonQ, in collaboration with Element Six, a leading synthetic diamond specialist under the UK’s De Beers Group, has developed a quantum-grade synthetic diamond film compatible with existing semiconductor manufacturing processes. This new technology is hailed as an innovation that overcomes a key bottleneck in quantum networking hardware production, enabling industrial-scale mass production beyond the laboratory scale.
Notably, it is compatible with standard foundry processes used in the $1 trillion semiconductor industry. It enables the heterogeneous integration of diamond-based quantum memory with other devices, accelerating the commercialization of photonic interconnects and quantum computing devices.
Based on this technological progress, IonQ is pursuing an ambitious roadmap targeting 2 million physical qubits by 2030. This corresponds to approximately 40,000 to 80,000 logical qubits, with commercialization planned for a 10,000 physical qubit single chip in 2027 and a 20,000 qubit system using two connected chips in 2028.
By achieving high qubit reliability (logical error rate below 1E-12), the company is moving closer to realizing fully fault-tolerant quantum computing for healthcare, artificial intelligence, and cybersecurity. This synthetic diamond film development builds upon last year’s acquisitions of Oxford Ionics’ 2D ion trap and photonic-based network technology Lightsynq.
Financially, IonQ has secured solid cash liquidity with revenue growing 68% over the past year. Its Q2 2025 revenue reached $20.7 million, exceeding the high end of expectations by 15%. The company maintains approximately $1.6 billion in cash, cash equivalents, and investments, providing ample funding for R&D, M&A, and commercialization expansion.
With a stock price increase of over 500% in three years and a portfolio of global clients including Amazon AWS, AstraZeneca, and NVIDIA, IonQ is solidifying its global leadership in quantum computing and networking technology.
The CFO-COO appointment and synthetic diamond innovation signify a major inflection point for IonQ to strengthen both its technological capabilities and management prowess, securing a significant lead in the fiercely competitive quantum computing market. The ripple effects across quantum science and industry are anticipated.
