- Title: Experimental Implementation of Efficient Quantum Pseudorandomness on a 12-spin System
- Abstract:Quantum pseudorandomness, also known as unitary designs, comprises a powerful resource for emergent quantum technologies. Although in theory pseudorandom unitary operators can be constructed efficiently, realizing these objects in realistic physical systems is a challenging task. Here, we demonstrate experimental generation and detection of quantum pseudorandomness on a 12-qubit nuclear magnetic resonance system. We first apply random sequences to the interacting nuclear spins, leading to random quantum evolutions that can quickly form unitary designs. Then, in order to probe the growth of quantum pseudorandomness during the time-evolutions, we propose the idea of using the system’s multiple-quantum coherence distribution as an indicator. Based on this indicator, we measure the spreading of quantum coherences and find that substantial quantum pseudorandomness has been achieved at the 12-qubit scale. This may open up a path to experimentally explore quantum randomness on forthcoming large-scale quantum processors.

- Title: 专用量子计算机的应用算法
- Abstract:在不久的将来，我们可以预期学术界和工业界在量子计算机的研发上有持续的突破。比如对于 50 个量子比特以上的量子芯片，能够达到非常高精度的调控技术。很有可能对于一些特定的计算任务，这些量子芯片能够执行到一个程度，是经典计算机无法有效模拟的。可是，这些芯片的量子比特个数还是远远不足以实现教科书里面的量子算法。当前的一个重大的问题就是，如何开发针对近期量子芯片的应用，去解决一些实际的科学或者工程问题？此外，对于一般用户，我们预期这些算力强大的专用量子机能够通过互联网，作为一种云服务去访问。这种形式的量子计算云服务也引发出不少学术问题，比如说，如何验证互联网背后的服务器是否带有真正的量子计算机而不是一个经典模拟器？
