Researchers at the Joint Quantum Institute (JQI) and the University of Maryland have developed a new method for creating quantum-entangled images using a technique called four-wave mixing. This method involves shining two laser beams into a cloud of rubidium gas, which produces two entangled images – one from the original pattern and an inverted, upside-down copy.
The key advantages of this new method are its simplicity, versatility, and efficiency. Unlike previous methods, it can create entire images at once and produce a wide variety of shapes. The technique also requires only easy-to-prepare laser beams and a small cell of rubidium vapor.
The potential applications of this new method are vast, including secure communication systems and quantum computing. The researchers are eager to continue exploring the possibilities of this new technique and are working to scale up the production of quantum images and investigate their properties in more detail.
This breakthrough in producing quantum-entangled images is considered a significant contribution to the field of quantum physics and has the potential to revolutionize the development of quantum technologies.
