- Abstract: Microfabricated ion-trap devices offer a promising pathway towards scalable
quantum computing. Research efforts have begun to focus on the engineering
challenges associated with developing large-scale ion-trap arrays and networks.
However, increasing the size of the array and integrating on-chip electronics
can drastically increase the power dissipation within the ion-trap chips. This
leads to an increase in the operating temperature of the ion-trap and limits
the device performance. Therefore, effective thermal management is an essential
consideration for any large-scale architecture. Presented here is the
development of a modular cooling system designed for use with multiple
ion-trapping experiments simultaneously. The system includes an extensible
cryostat that permits scaling of the cooling power to meet the demands of a
large network. Following experimental testing on two independent ion-trap
experiments, the cooling system is expected to deliver a net cooling power of
111 W at ~70 K to up to four experiments. The cooling system is a step towards
meeting the practical challenges of operating large-scale quantum computers
with many qubits.

A quantum charge-coupled device (QCCD) is a leading candidate for advanced quantum information processing.
Here, we demonstrate a different approach we call exchange cooling.
Unlike sympathetic cooling, exchange cooling does not require trapping two different atomic species.
This approach validates the feasibility of a single-species QCCD processor, capable of fast quantum simulation and computation.

In small satellites there is less room for heat control equipment, scientific instruments, and electronic components.
An autonomous thermal control tool that uses deep reinforcement learning is proposed for learning the thermal control policy onboard.
The proposed framework is able to learn to control the payload processing power to maintain the temperature under operational ranges.

We show how to implant low-energy ions into silicon devices featuring an enlarged 60x60 $mu$m sensitive area.
Despite the weak internal electric field, near-unity charge collection efficiency is obtained from the entire sensitive area.
This can be explained by the critical role that the high-quality thermal gate oxide plays in the ion detection response.

Reservoir engineering is a remarkable task that takes dissipation and decoherence as tools rather than impediments.
We develop a collisional model to implement reservoir engineering for the one-dimensional harmonic motion of a trapped ion.
Having multiple internal levels, we show that multiple reservoirs can be engineered, allowing for more efficient synthesis of well-known non-classical states of motion.
