Solid neon enables noise-resilient electron qubits for quantum computing
In a study published in Nature Electronics, researchers show that solid neon enables electron qubits to operate with low noise and long coherence times above 100 mK, paving the way for more scalable and robust quantum computing technologies.

Scientific Achievement

Researchers demonstrated resilience of solid neon against charge and thermal noise. The high-frequency noise levels of eNe qubits are measured thousands of times lower than most traditional charge qubits.

Significance and Impact

This work provides a sustainable and modular strategy for enhanced hydrogen peroxide production and coupled organic transformations, demonstrating the potential of abiotic–biotic hybrid platforms for chemical manufacturing and energy applications.

Research Details

  • The superconducting quantum circuit was fabricated in the CNM cleanroom using JEOL electron-beam lithography and Oxford reactive ion etching.
  • The low-temperature quantum experiments were performed in CNM quantum labs using a Bluefors dilution refrigerator system.
