We present a new quantum computing architecture using a spin bus for controllable long-range interactions. This design enables scalable solid-state quantum computation with existing experimental resources.

Area of Science:

  • Quantum Information Science
  • Solid-State Physics
  • Quantum Computing Architectures

Background:

  • Controllable long-range couplings are crucial for scalable quantum computation.
  • Existing architectures face challenges in achieving robust and controllable interactions.

Purpose of the Study:

  • To propose an experimentally feasible architecture for controllable long-range couplings.
  • To demonstrate the generation of entangled states using this architecture.

Main Methods:

  • Utilizing a spin bus with strong, always-on interactions.
  • Dynamically coupling the spin bus to external qubits (Loss and DiVincenzo type).
  • Leveraging a spectral gap in a finite-size chain to enable long-range correlations.
