Inhibiting the self-discharging process of quantum batteries in non-Markovian noises.

One of the main challenges in developing high-performance quantum batteries is the self-discharging process, where energy is dissipated from a quantum battery into the environment. In this work, we investigate the influence of non-Markovian noises on the performance of a quantum battery. Our results demonstrate that adding auxiliary qubits to a quantum battery system can effectively suppress the self-discharging process, leading to an improvement in both the steady-state energy and extractable work.

Young's double-slit interference with two-color biphotons.

In classical optics, Young's double-slit experiment with colored coherent light gives rise to individual interference fringes for each light frequency, referring to single-photon interference. However, two-photon double-slit interference has been widely studied only for wavelength-degenerate biphoton, known as subwavelength quantum lithography. In this work, we report double-slit interference experiments with two-color biphoton.

[A systematic evaluation of randomized controlled trials for acupuncture and moxibustion treatment of insomnia].

Objective: To assess the therapeutic effect of acupuncture on insomnia.

Methods: A systematic evaluation of all relevant randomized controlled trials (RCT) about acupuncture and moxibustion treatment of insomnia was carried out. The data were statistically analyzed with a special software RevMan 4.

Experimental observation of classical subwavelength interference with a pseudothermal light source.

We report the experimental observation of classical subwavelength double slit interference with a pseudothermal light source. The experimental results are in good agreement with the theoretical simulation using the second order correlation function for the thermal light.
