The team even transmitted video games through the atoms to a monitor.
In a glass container, two different color lasers were used to preparein Rydberg states. The researchers previously relied on the arrangement with cesium atoms to demonstrate the basic radio receiver and a "headphone" appliance to "boost sensitivity a hundredfold".
To prepare the radio receiver, a stable carrier signal is applied to the glass container, which comprises the Rydberg atoms. This signal is modulated using input from a video camera or other source. Next, the modulated signal is transmitted through a horn antenna to the atoms - which causes an energy shift.
The researchers found that small beam diameters for both lasers led to faster responses and color reception - a data rate of 100 megabits per second was achieved. This is an excellent speed for video gaming and household internet. However, the atomic television may take a while to be part of your home entertainment setup; research is ongoing to increase the system's bandwidth and data rates.We demonstrate the ability to receive live color analog television and video game signals with the use of the Rydberg atom receiver. The typical signal expected for traditional 480i National Television Standards Committee format video signals requires a bandwidth of over 3 MHz.
