Compact Ion-Trap Quantum Computing Demonstrator

Quantum information processing is steadily progressing from a purely academic discipline towards applications throughout science and industry. Transitioning lab-based, proof-of-concept experiments to robust, integrated realizations of quantum hardware an important step in this process. However, the nature traditional laboratory setups does not offer itself readily scaling up system sizes or allow for outside laboratory-grade environments. This transition requires overcoming challenges engineering integration without sacrificing state-of-the-art performance implementations. Here, we present 19-inch rack computing demonstrator based on $^{40}\textrm{Ca}^+$ optical qubits linear Paul trap address many these challenges. We outline mechanical, optical, electrical subsystems. Further, describe automation remote access components stack. conclude by describing characterization measurements relevant digital including entangling operations mediated Molmer-Sorenson interaction. Using setup produce maximally-entangled Greenberger-Horne-Zeilinger states with 24 ions use post-selection error mitigation techniques; par well-established conventional setups.
