Low-Loss Quantum Interconnect for Distributed Quantum Computing
Analysis
Key Takeaways
- •Demonstrates a low-loss quantum interconnect using an aluminum coaxial cable.
- •Achieves high-fidelity state transfer between superconducting modules.
- •Shifts the performance bottleneck from transmission losses to module-channel interface effects and local Kerr nonlinearities.
- •Paves the way for scalable distributed quantum computing and efficient quantum communications.
“The state transfer fidelity reaches 98.2% for quantum states encoded in the first two energy levels, achieving a Bell state fidelity of 92.5%.”
