NIST, in collaboration with Fermilab’s SQMS Center and other partners, is making significant progress in improving quantum computing technology. A key focus is on enhancing the performance of superconducting qubits, which are essential components of quantum computers. Researchers are working to increase qubit coherence times—how long qubits can maintain their quantum state—by using advanced fabrication techniques, such as encapsulating niobium qubits with materials like gold or tantalum. These improvements help reduce material losses and make quantum computers more reliable and powerful.
The work is part of the SQMS Nanofabrication Taskforce, led by NIST scientists who are refining both materials and fabrication processes. Recent advancements have achieved coherence times of up to 0.6 milliseconds, a major step forward in superconducting quantum technology. Researchers are also exploring new superconducting materials and improving Josephson junctions to further boost performance. These efforts aim to build scalable, fault-tolerant quantum computers, which could revolutionize fields like healthcare, cybersecurity, and economic growth by enabling faster drug discovery, stronger encryption, and new industries.
