Given the impeding timeline of developing good quality quantum processing units, it is the moment to rethink the approach to advance quantum computing research. Rather than waiting for quantum hardware technologies to mature, we need to start assessing in tandem the impact of the occurrence of quantum computing in various scientific fields. However, to this purpose, we need to use a complementary but quite different approach than proposed by the NISQ vision, which is heavily focused on and burdened by the engineering challenges. That is why we propose and advocate the PISQ approach: Perfect Intermediate Scale Quantum computing based on the already known concept of perfect qubits. This will allow researchers to focus much more on the development of new applications by defining the algorithms in terms of perfect qubits and evaluate them on quantum computing simulators that are executed on supercomputers. It is not the long-term solution but will currently allow universities to research on quantum logic and algorithms and companies can already start developing their internal know-how on quantum solutions.

量子计算——从 NISQ 到 PISQ


鉴于开发高质量量子处理单元的时间紧迫，现在是重新思考推进量子计算研究的方法的时候了。我们不需要等待量子硬件技术成熟，而是需要开始同时评估量子计算的出现对各个科学领域的影响。然而，为此目的，我们需要使用一种与 NISQ 愿景所提出的补充但完全不同的方法，NISQ 愿景高度关注工程挑战并为其带来负担。这就是为什么我们提出并提倡 PISQ 方法：基于已知的完美量子位概念的完美中级量子计算。这将使研究人员能够通过根据完美量子位定义算法并在超级计算机上执行的量子计算模拟器上对其进行评估，从而更加专注于新应用程序的开发。这不是长期解决方案，但目前将允许大学研究量子逻辑和算法，公司也可以开始开发有关量子解决方案的内部专业知识。
