Advanced quantum computers will use modular measurements significantly enhancing their capabilities. However, due to the noisy environment, the measurements may have nontrivial effects on the computation. Making best use of realistic (hence imperfect) measurements is a challenging problem that hinders the development of these technologies. This project, using modern tools of resource theory, aims to design optimal realistic measurement procedures for near-term noisy quantum devices. The expected outcomes of the project are refined methods to optimise quantum measurements in today's rudimentary quantum machines. This will provide a significant benefit to the Australian community, advancing the development of disruptive quantum technologies.

先进的量子计算机将使用模块化测量，大大提高其能力。然而，由于噪声环境的存在，测量结果可能会对计算产生不小的影响。充分利用现实的（因此不完美的）测量是一个具有挑战性的问题，它阻碍了这些技术的发展。本项目利用资源理论的现代工具，旨在为近期噪声量子器件设计最佳的现实测量程序。该项目的预期成果是改进方法，以优化当今基本量子机器中的量子测量。这将为澳大利亚社会带来重大利益，推动颠覆性量子技术的发展。
