This document presents a concise overview of the contemporary research directions in quantum computer cybersecurity. The aim of this document is not to be a survey, but rather a succinct summary of the major research directions in quantum computer cybersecurity at the end of the first half of the current decade. The document has been inspired by the presentations and discussions held at the 3$^{rd}$ Quantum Computer Cybersecurity Symposium, but goes beyond the contents of the symposium and aims to summarize at the high level the last five years of quantum computer cybersecurity work in academia. It is hoped that the document can provide researchers as well as government and industry leaders an overview of the current landscape of security threats and defenses against emergent quantum computing technologies. The document also includes a discussion of the current trends in cybersecurity research on quantum computers, and the perceived research gaps that should be filled with future funding and through academic and industry~research.

翻译：本文对当前量子计算机网络安全的研究方向进行了简明概述。本文的目的并非全面综述，而是对当前十年上半叶结束时量子计算机网络安全主要研究方向的精炼总结。本文的撰写灵感来源于第三届量子计算机网络安全研讨会的报告与讨论，但内容超越了研讨会范畴，旨在从宏观层面总结学术界近五年来在量子计算机网络安全领域的工作。期望本文能为研究人员、政府及行业领导者提供关于新兴量子计算技术所面临安全威胁与防御措施的现状概览。文中还探讨了当前量子计算机网络安全研究的趋势，以及需要通过未来资金投入和产学研合作填补的认知研究空白。
