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: In this talk, we will give two quantum applications based on density matrix vectorization. Vectorizing density matrices has been a useful mathematical trick for simplifying many concepts in...
Abstract: A central challenge in developing magnetically coupled quantum registers in diamond is the fabrication of nitrogen vacancy (NV) centers with localization below ∼20 nm to enable fast dipola...
Abstract: Entanglement and superposition are fundamental properties of quantum-mechanical states, with no classical counterparts. It is well-established that elementary particles, such as electrons a...
Abstract: We experimentally resolve several weakly coupled nuclear spins in diamond using a series of dynamical decoupling controls. Some nuclear spin signals, hidden by decoherence under ordinary dy...
Abstract: Magic states are essential yet resource-intensive components for realizing universal fault-tolerant quantum computation. Preparing magic states within emerging quantum low-density parity-ch...
