Abstract: 为了实现大规模容错量子计算,我们必须有探测和纠正噪声的手段——量子纠错。在过去的二十年里,人们构造了一系列不同的量子纠错码,但其中的绝大部分并不适用于近期量子设备。在这个报告里,我们介绍一个...
Abstract: The recognition of entanglement states is a notoriously difficult problem when no prior information is available. Here, we propose an efficient quantum adversarial bipartite entanglement de...
Abstract: Recent breakthroughs have opened the possibility to intermediate-scale quantum computing with tens to hundreds of qubits, and shown the potential for solving classical challenging problems,...
Abstract: The ultimate goal of quantum computing is to build a fault-tolerant quantum computer (FTQC), where the number of qubits is sufficiently large and the error rate is satisfactorily low, such ...
Abstract: Universal quantum computers offer us the opportunities to implement novel quantum matter far away from equilibrium states. There has been remarkable progress in our understanding of the non...
Abstract: The increasing scale of near-term quantum hardware motivates the need for efficient noise characterization methods, since qubit and gate level techniques cannot capture crosstalk and correl...
