Chinese scientists have successfully developed a quantum superconducting diode that is incredibly thin, measuring just one seven-hundredth of the thickness of a human hair. This remarkable device is capable of operating with zero energy consumption and high efficiency within the temperature range of liquid nitrogen (minus 196 degrees Celsius). It boasts a rectification efficiency of 100% and possesses properties that make it resistant to quantum noise.

On November 28, the pertinent research findings were published in Nature Physics, paving the way for the development of a new generation of superconducting electronic devices. This device achieves zero dissipation by leveraging a quantum entanglement mechanism, where electrons form pairs. This mechanism effectively addresses the issue of heat generation caused by the erratic movement of electrons in traditional superconducting diodes, while also enhancing the device's resistance to noise.

Notably, the operating temperature range of this device is nearly 10 times higher than that of the previous liquid helium temperature range (minus 269 degrees Celsius). This advancement significantly reduces cooling costs and represents a crucial technological breakthrough for various fields, including quantum computing, low-power chips, and green energy.
