Zoned neutral atom quantum computer schedule optimization

A method for configuring an array of atoms for performing a quantum computation, the method comprising:

• providing a quantum register including an optical trap array having a plurality of zones, the plurality of zones including an interaction zone and a storage zone;
• receiving a plurality of constraints at a scheduling optimizer;
• determining by the scheduling optimizer, an optimized atom schedule that optimizes a value of an objective function that correlates to minimizing a logical error rate while performing the quantum computation and respecting the plurality of constraints including:
• hardware constraints that include an interaction zone geometry based on doublons, a storage zone geometry, and movement constraints within the array of atoms between the interaction zone and the storage zone, the interaction zone geometry including the doublons,
• circuit scheduling that includes initial qubit placement in the optical trap array, gate groupings in the doublons in the interaction zone, and
• qubit groupings for simultaneous moves between the interaction zone and the storage zone;
• and
• receiving the optimized atom schedule by an optical trap generator coupled to the scheduling optimizer;
• deflecting a trapping laser into a first direction and a second direction to form the optical trap array using the optical trap generator;
• and
• moving the array of atoms by the optical trap generator between the doublons in the interaction zone and the storage zone in the optical trap array responsive to the optimized atom schedule.
