| 2 | Experimental realization of a quantum image classifier via tensor-network-based machine learning显示文摘Quantum machine learning aspires to overcome intractability that currently limits its applicability to practical applications.However,quantum machine learning itself is limited by low effective dimensions achievable in stateof-the-art experiments.Here,we demonstrate highly successful classifications of real-life images using photonic qubits,combining a quantum tensor-network representation of hand-written digits and entanglement-based optimization.Specifically,we focus on binary classification for hand-written zeroes and ones,whose features are cast into the tensor-network representation,further reduced by optimization based on entanglement entropy and encoded into two-qubit photonic states.We then demonstrate image classification with a high success rate exceeding 98%,through successive gate operations and projective measurements.Although we work with photons,our approach is amenable to other physical realizations such as nitrogen-vacancy centers,nuclear spins,and trapped ions,and our scheme can be scaled to efficient multi-qubit encodings of features in the tensor-product representation,thereby setting the stage for quantum-enhanced multi-class classification. | KUNKUN WANG LEI XIAO WEI YI SHI-JU RAN PENG XUE | 2021 | Photonics Research2021，9，12： | 2 |
| 3 | Experimental witnessing for entangled states with limited local measurements显示文摘We experimentally demonstrate a method for detection of entanglement via construction of entanglement witnesses from a limited fixed set of local measurements(M).Such a method does not require a priori knowledge about the form of the entanglement witnesses.It is suitable for a scenario where a full state tomography is not available,but the only resource is a limited set of M.We demonstrate the method on pure two-qubit entangled states and mixed two-qubit entangled states,which emerge from photonic implementation of controllable quantum noisy channels.The states we select are motivated by realistic experimental conditions,and we confirm it works well for both cases.Furthermore,possible generalizations to higher-dimensional bipartite systems have been considered,which can potentially detect both decomposable and indecomposable entanglement witnesses.Our experimental results show perfect validity of the method,which indicates that even a limited set of local measurements can be used for quick entanglement detection and further provide a practical test bed for experiments with entanglement witnesses. | GAOYAN ZHU CHENGJIE ZHANG KUNKUN WANG LEI XIAO PENG XUE | 2022 | Photonics Research2022，10，9： | 0 |
