噪声中尺度量子(NISQ)技术将在不久的将来推出。拥有50-100个量子比特的量子计算机可能能够执行超过当今经典数字计算机能力的任务，但量子门中的噪声将限制能够可靠执行的量子电路的大小。NISQ设备将成为探索多体量子物理的有用工具，并可能有其他有用的应用，但100量子位量子计算机不会立即改变世界-我们应该将其视为朝着未来更强大的量子技术迈出的重要一步。量子技术专家应该继续努力开发更精确的量子门，并最终实现完全容错的量子计算。
Noisy Intermediate-Scale Quantum (NISQ) technology will be available in the near future. Quantum computers with 50-100 qubits may be able to perform tasks which surpass the capabilities of today's classical digital computers, but noise in quantum gates will limit the size of quantum circuits that can be executed reliably. NISQ devices will be useful tools for exploring many-body quantum physics, and may have other useful applications, but the 100-qubit quantum computer will not change the world right away - we should regard it as a significant step toward the more powerful quantum technologies of the future. Quantum technologists should continue to strive for more accurate quantum gates and, eventually, fully fault-tolerant quantum computing.
