High Optical Access Trap

{{ page.title }}

Ion trap and rendering of experimental apparatus

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

Illustration of usage of spectator qubits

Fast B-field fluctuation compensation by measuring spectator qubits and adjusting laser frequency.

Illustration of sympathetic cooling

Sympathetic cooling on spectator ions' motional modes to cool logical qubits.
