State-dependent lattices for quantum computing with alkaline-earth-metal atoms

1 min read

Extends alkaline-earth clock-state qubit architectures with nuclear-spin-dependent optical lattices for gate operations and addressing.

Abstract

Recent experimental progress with alkaline-earth atoms has opened the door to quantum computing schemes in which qubits are encoded in long-lived nuclear spin states, and metastable electronic states are used for manipulation and readout. This work details a variant using nuclear-spin-dependent optical lattices and expands the gate toolbox.

Key Findings

  • Refines the original alkaline-earth clock-state qubit proposal into a more detailed control architecture.
  • Clarifies implementation pathways for addressing and entangling operations.
