Summary: Accurate measurement of mouse magnetocardiography (MCG) is crucial for heart disease research. However, conventional measuring instruments such as superconducting quantum interference devices (SQUIDs) have limitations in terms of size, cost, and promotion. To overcome these challenges, we developed a mouse MCG measurement system using a spin-exchange-relaxation-free (SERF) atomic magnetometer. This system includes a magnetic sensor, a mouse fixation device, a magnetically shielded device, and a data acquisition and processing module. Through experiments and analysis, we demonstrated the advantages of our proposed system in detecting mouse MCG signals.

Summary: Ensembles of dopants have wide applications in quantum technology, but the miniaturization of corresponding devices is hindered by dipolar interactions. Dynamical decoupling can alleviate the decoherence in crystals with strong anisotropic spin-spin interactions, originating from anisotropic g tensor, but cannot fully eliminate it. These findings can be extended to various quantum systems used for quantum sensing, microwave-to-optical conversion, and quantum memory.

Summary: A long-lived memory qubit was successfully integrated into a mixed-species trapped-ion quantum network node. Ion-photon entanglement was initially generated between a network qubit in 88Sr+ and transferred to 43Ca+ with a fidelity of 0.977(7), and then mapped to a robust memory qubit. The network qubit was further entangled with a second photon without affecting the memory qubit. Quantum state tomography showed that the decay of ion-photon entanglement fidelity on the memory qubit was about 70 times slower. Dynamical decoupling extended the storage duration, achieving an ion-photon entanglement fidelity of 0.81(4) after 10 s.

Summary: In recent proposals of quantum circuit models for generative tasks, the evaluation of their performance has been focused on reproducing known target distributions. However, this approach limits the assessment of generative models to data memorization rather than generalization. This work addresses this knowledge gap by introducing a generalization evaluation framework. The study demonstrates that the quantum circuit Born machine (QCBM) exhibits improved generalization performance when increasing circuit depth, and it can effectively learn and generate unseen high-quality samples.
