Long-lived Qubits: Unlocking Utility-Scale Quantum Computing

Quantum computing has entered an era where scalable architecture is increasingly evaluated by qubit count, gate fidelity and hardware complexity. Yet many of the most promising future workloads—including quantum error correction, hybrid quantum-classical optimization, quantum machine learning and distributed quantum computing—share a common requirement: time. They require quantum states to remain coherent long enough to support increasingly deep computational workflows. 

In this talk, I will discuss why coherence time is not merely another hardware metric, but one of the fundamental resources that will unlock utility-scale quantum computing. I will present how Qudora´s Near-Field Quantum Control (NFQC) provides the foundation for this vision by combining ultra-low noise qubit control with intrinsically long coherence times in a scalable trapped-ion architecture. Together, these capabilities enable deeper quantum circuits, more efficient fault-tolerant operation, and a practical path toward commercially useful quantum computing.
