Description
Quantum simulators are platforms used to simulate classically intractable quantum systems. The ability to select an initial state, engineer interactions and select a measurement scheme enables a programmatic way to study quantum effects. Trapped atomic ions provide a versatile quantum simulation testbed due to their native all-to-all interactions, long coherence times and simple qubit state manipulation schemes. We present a large-scale quantum simulator, engineered to hold over 30 171Yb+ ion-qubits for both analog and digital quantum processing. The system incorporates an extreme high vacuum chamber (XHV), site selective qubit addressing, in situ mid-circuit measurement and reset, and high numerical aperture (NA) imaging for rapid state detection. We measure a local pressure of (3.9 ± 0.3) × 10−12 mbar using the ions in the room temperature system [1], corresponding to a long average interval of (1.9 ± 0.1) hrs/ion for collisions with background atoms, suitable for large scale quantum simulation experiments. Furthermore, a dual acousto-optical deflector (AOD) configuration has been implemented for site-selective addressing, as our means to implement single and multi-qubit logical operations. Using Fourier holography, a pristine beam is engineered to address a single ion with low-crosstalk to measure and reset a qubit state during a circuit [2]. This platform is intended to enable a wide range of quantum simulation experiments, including investigations of driven-dissipative quantum dynamics and measurement-driven quantum phase transitions.
