High Optical Access Trap

Ion trap and rendering of experimental apparatus — Illustration of experimental setup, including the HOA trap from Sandia, the feedthrough and support assembly, and the available trapping regions.

Diagram of trapping regions — Illustration of experimental setup, including the HOA trap from Sandia, the feedthrough and support assembly, and the available trapping regions.

Key features:

High optical access, including slit for access from bottom.
Separate loading, storage, and quantum regions.
100 individually controlled electrodes for fast and precise shuttling, splitting, merging.

Entangle Long Chains of Ions (STAQ)

Illustration of pairwise gates on distant ions — Entangling long chains of ions using pairwise Mølmer-Sørensen gates on distant ions and ion shuttling.

Illustration of ion chain splitting — Splitting and shuttling entangled states. Measure Bell violation (CHSH) to test entanglement robustness to ions' shuttling.

Spectator Qubits (MURI)

Using Calcium-40 as logical qubit, we have two options for spectator qubit:

Calcium-48
Strontium
