    CIE Retreat - 1979?
    (1979-09)
    That year the annual CIE retreat was held at Fox Run, a resort hotel in western Massachusetts as we looked for more suitable locations for future retreats.

    CIE Retreat - Camp Bement - 1980
    (1980-09)
    This was the first retreat held at Camp Bement, a summer camp in central Massachusetts owned by a group of churches, that CIE used for many years thereafter for its annual retreats. This version features a complete list of names of those in the picture.

    Multi-Objective Evolutionary Architecture Search for Parameterized Quantum Circuits
    (2023) Ding, Li; Spector, Lee
    Recent work on hybrid quantum-classical machine learning systems has demonstrated success in utilizing parameterized quantum circuits (PQCs) to solve the challenging reinforcement learning (RL) tasks, with provable learning advantages over classical systems, e.g., deep neural networks. While existing work demonstrates and exploits the strength of PQC-based models, the design choices of PQC architectures and the interactions between different quantum circuits on learning tasks are generally underexplored. In this work, we introduce a Multi-objective Evolutionary Architecture Search framework for parameterized quantum circuits (MEAS-PQC), which uses a multi-objective genetic algorithm with quantum-specific configurations to perform efficient searching of optimal PQC architectures. Experimental results show that our method can find architectures that have superior learning performance on three benchmark RL tasks, and are also optimized for additional objectives including reductions in quantum noise and model size. Further analysis of patterns and probability distributions of quantum operations helps identify performance-critical design choices of hybrid quantum-classical learning systems.
