A computer-generated hologram compression and transmission system is designed. The system uses a hybrid neural network based on quantum compensation to compress and decompress computer-generated holograms and uses a quantization method and Huffman coding to encode the compressed holograms for transmission. The receiving side decodes and decompresses the data stream to obtain the recovered hologram, which can be used to reconstruct the original object information for 3D image display. Our numerical experiments show that quantum compensation can improve the quality of the reconstructed image. Furthermore, we introduce a quantum compensation factor to describe the strength of quantum compensation and verify experimentally that the quantum compensation module may drive the conventional neural network to converge in fewer training epochs.

The exceptional performance of ceria (CeO) in catalysis and energy conversion is fundamentally governed by its defect chemistry, particularly oxygen vacancies. The formation of each oxygen vacancy (V) is assumed to be compensated by two localized electrons on cations (Ce). Here, we show by combining theory with experiment that while this 1 V: 2Ce ratio accounts for the global charge compensation, it does not apply at the local scale, particularly in nanoparticles.

In this paper, two conclusive three-party cyclic assisted cloning protocols in amplitude damping (AD) channel are put forward that, respectively clone three arbitrary unknown single-qubit states and single-qutrit states with the help of a state preparer. Each of our protocols includes three consecutive stages: quantum channel preparation, cyclic quantum teleportation (CQT), and multi-party assisted cloning. The first stage of each protocol proposes the detailed processes of sharing a pure entangled quantum state as a component of a quantum channel in AD channel via entanglement compensation.

Background: Tracking irradiation to moving targets in spot-scanning particle therapy, which corrects the spot position and energy in real-time, may decrease treatment time and increase accuracy. However, because of the temporal performance of the system, clinical translation remains challenging. Processing time, including image acquisition, volumetric image synthesis, correction assessment, and system response, is required to control the actual treatment system.

Ferrimagnets that can be driven to magnetic compensation show promise for use in spintronics as they exhibit a finite anomalous Hall effect at zero magnetic field without having a substantial magnetic moment. Compensated ferrimagnet spintronic devices with both a large anomalous Hall effect and a high coercivity would be simultaneously easy to read and difficult to erase. The kagome ferrimagnet TbMnSn has been reported to host a large intrinsic anomalous Hall effect.
