New Quantum Light Source, A Step To The Future Of Quantum Chips

According to the latest reports, it seems that Chinese experts are developing new quantum light sources as a step towards the future of quantum chips. Here are more details about this below.

Enter the future of quantum chips

A team of researchers in China has successfully developed a quantum light source using a common semiconductor called gallium nitride (GaN).

This marks a significant step towards building a functional quantum chip. GaN is typically used in blue light-emitting diodes and the team’s use of this material to create a crucial component for quantum computation is a promising advancement.

According to the South China Morning Post, the development has been reported recently.

Researchers from the University of Electronic Science and Technology of China (UESTC), Tsinghua University, and the Shanghai Institute of Microsystem and Information Technology have developed a quantum light source that has the ability to generate pairs of entangled light particles.

These particles are foundational for transmitting information within quantum systems.

The development could lead to more efficient quantum chips that are easier to integrate into quantum devices, according to newspaper reports. The scientists believe that the potential applications in quantum computing are vast.

According to an article in Physical Review Letters, the device offers a broader range of wavelengths than existing quantum light sources that typically rely on materials such as silicon nitride and indium phosphide.

“We demonstrate that gallium nitride is a good quantum material platform for photonic quantum information, in which the generation of quantum light is crucial,” lead author Zhou Qiang said in Physics Magazine recently.

The GaN-based quantum light source has a wider wavelength range and can also pave the way for developing other crucial components for quantum circuits.

Thomas Walther from the Technical University of Darmstadt told Physics Magazine that this is a significant advancement that could greatly reduce the costs and size of these systems, making them more durable and compact.

This development is a major step forward for the field of quantum computing.
