In February 2026, a significant breakthrough was achieved in the field of topological quantum computing by an international collaborative research team. This team comprised experts from the Madrid Institute for Materials Science, affiliated with the Spanish National Research Council, and Delft University of Technology in the Netherlands. For the first time, they successfully read information from topological qubits, which are based on Majorana modes, utilizing a novel technology known as "quantum capacitance." This milestone paves the way for more stable quantum computing systems. The groundbreaking findings were published in the prestigious journal Nature.

Topological qubits inherently possess a robustness against local noise, a characteristic attributed to their non-local information distribution. However, the challenge of reading information from these qubits has long been a technical hurdle. By constructing modular nanostructures and integrating "quantum capacitance" probe technology, the research team accomplished, for the first time, the real-time, single-shot reading of non-local quantum states. Moreover, they measured a parity coherence time exceeding 1 millisecond, offering crucial experimental evidence for the feasibility of topological quantum computing.
