Infleqtion has leapfrogged a major hurdle in quantum computing, unveiling research with the University of Wisconsin–Madison that achieves 99.93% reliability in measuring qubits – the fundamental building blocks of quantum computers – without disrupting their delicate states. This breakthrough addresses a critical bottleneck in scaling quantum systems, enabling faster computation cycles and more robust error correction. Researchers, led by Professor Mark Saffman’s group, combined precise measurement with continuous cooling to minimize disruptions. “If you can measure qubits accurately without losing them, you can move faster, repeat measurements more reliably, and build systems that scale beyond the laboratory. That is why this result matters,” said Dr. Pranav Gokhale, CTO at Infleqtion. The findings, published in Physical Review Letters, accelerate Infleqtion’s path towards industrial-scale neutral-atom quantum computers and represent a significant step toward practical, large-scale quantum computation.
Neutral-Atom Qubit Measurement Reduces Errors & Maintains States
Infleqtion and the University of Wisconsin–Madison have demonstrated a significant advance in neutral-atom quantum computing, achieving 99.93% reliability in qubit measurement without disrupting quantum states. This breakthrough centers on a technique combining precise measurement with continuous cooling, a method designed to minimize errors that typically plague increasingly complex quantum systems. Conventional measurement methods often introduce inaccuracies or data loss, hindering scalability—a challenge this research directly tackles by enabling more efficient computation cycles. “High-fidelity, nondestructive measurement is a key requirement for scaling neutral atom quantum systems,” said Professor Mark Saffman.
The collaborative effort, spearheaded by Professor Saffman’s group, represents a practical pathway toward faster and more dependable quantum operations, transitioning the technology from tightly controlled experiments to larger-scale computation. This achievement is crucial for building systems that surpass laboratory limitations and opens avenues for robust error correction. Pranav Gokhale, CTO at Infleqtion.

Infleqtion & UW-Madison Advance Scalable Quantum Computation Cycles
The research, published in Physical Review Letters, tackles the problem of maintaining fragile quantum states during measurement, a notorious impediment to scaling up quantum processors. By integrating precise measurement techniques with continuous cooling, the team minimized disruptions to ongoing quantum circuits, paving the way for faster computation cycles and more effective error correction. “This work addresses a fundamental bottleneck in quantum computing,” said Dr. Pranav Gokhale, CTO at Infleqtion. This advancement allows for more reliable repetition of measurements, a necessity for building larger, more complex quantum systems capable of surpassing current laboratory limitations.
