Digital-analog quantum computing (DAQC) is an alternative paradigm for
universal quantum computation combining digital single-qubit gates with global
analog operations acting on a register of interacting qubits. Currently, no
available open-source software is tailored to express, differentiate, and
execute programs within the DAQC paradigm. In this work, we address this
shortfall by presenting Qadence, a high-level programming interface for
building complex digital-analog quantum programs developed at Pasqal. Thanks to
its flexible interface, native differentiability, and focus on real-device
execution, Qadence aims at advancing research on variational quantum algorithms
built for native DAQC platforms such as Rydberg atom arrays.

数字 - 模拟量量子计算（DAQC）是一种将数字单量子比特门与作用于相互作用量子比特寄存器的全局模拟量操作相结合的通用量子计算的替代范式。本文介绍了 Pasqal 开发的用于构建复杂的数字 - 模拟量子程序的高级编程接口 Qadence，通过其灵活的界面、原生可区分性和对实际设备执行的关注，Qadence 旨在推动针对 Rydberg 原子阵等原生 DAQC 平台构建的变分量子算法的研究。
