量子计算正处于从基础研究向实际应用转变的边缘。然而，要迈向大规模量子计算，就必须开发一种可扩展的量子比特系统。在经典半导体技术中，集成电路的发明使这成为可能，它允许大量组件相互连接，而无需对每个组件都进行焊接。同样，我们预计，随着量子比特数量的增加，互连和控制线的扩展将成为创建大规模量子技术的核心瓶颈。在此，我们定义量子 Rent指数p，以量化在整个量子计算栈的不同层面克服这一挑战的进展。我们进一步讨论量子可扩展性的概念，将其作为一个平台实现通用量子计算所需的大量子体积潜力的指标，并回顾在迈向真正大规模量子比特系统的过程中不同量子比特实现所面临的可扩展性限制。（C）2019年由爱思唯尔公司出版
Quantum computing is on the verge of a transition from fundamental research to practical applications. Yet, to make the step to large-scale quantum computation, an extensible qubit system has to be developed. In classical semiconductor technology, this was made possible by the invention of the integrated circuit, which allowed to interconnect large numbers of components without having to solder to each and every one of them. Similarly, we expect that the scaling of interconnections and control lines with the number of qubits will be a central bottleneck in creating large-scale quantum technology. Here, we define the quantum Rent exponent p to quantify the progress in overcoming this challenge at different levels throughout the quantum computing stack. We further discuss the concept of quantum extensibility as an indicator of a platform's potential to reach the large quantum volume needed for universal quantum computing and review extensibility limits faced by different qubit implementations on the way towards truly large-scale qubit systems.
