New Qubit Architecture Paves Way for Scalable Quantum Computing
Brookhaven Lab scientists demonstrate that constriction junctions can match the performance of traditional SIS junctions, facilitating easier mass production.
- Researchers at Brookhaven National Laboratory have shown that qubits with constriction junctions can perform comparably to those with SIS junctions.
- The new architecture, featuring superconducting layers connected by a thin wire, is more compatible with standard semiconductor manufacturing processes.
- Constriction junctions allow for easier and more reliable large-scale production of qubits, addressing a significant barrier in quantum computing development.
- Scientists identified specific superconducting materials and design parameters that can optimize the nonlinearity and current flow in constriction junctions.
- This breakthrough aligns with the Co-design Center for Quantum Advantage's goal of developing scalable quantum computers through interdisciplinary collaboration.
