Quantum computing with alkaline earth atoms

Foundational alkaline-earth neutral-atom architecture proposal where qubits are encoded in long-lived nuclear-spin / clock-compatible manifolds with separate storage and transport operations.

Abstract

We present a complete scheme for quantum information processing using the unique features of alkaline earth atoms. We show how two completely independent lattices can be formed for the ${}^1$S${}_0$ and ${}^3$P${}_0$ states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations.

Key Findings

• Introduces a clock-state-compatible neutral-atom qubit architecture.
• Establishes a clear control/readout path using metastable manifolds.
