 Majorana qubits decoded in quantum computing breakthrough


Scientists have developed a new way to read the hidden states of Majorana qubits, which store information in paired quantum modes that resist noise. The results confirm their protected nature and show millisecond scale coherence, bringing robust quantum computers closer to reality.

"This is a crucial advance," says Ramón Aguado, a CSIC researcher at the Madrid Institute of Materials Science (ICMM) and co author of the study. He explains that the team has successfully retrieved information stored in Majorana qubits by applying a technique known as quantum capacitance. According to Aguado, this method functions as "a global probe sensitive to the overall state of the system," enabling scientists to access information that was previously difficult to observe. To clarify the importance of the result, Aguado describes topological qubits as "like safe boxes for quantum information." Instead of keeping data in one fixed location, these qubits spread information across two linked quantum states called Majorana zero modes. Because the data is distributed in this way, it gains natural protection.
