At Alberta University, physicists have developed a technology that allows data to be transferred between microwaves and light. This technology will enable it to be used in quantum computers and secure communication systems. The new technology works thanks to the strong between microwaves and atomic gas. Microwaves are modulating using an acoustic that encodes information within them. The modulation passes through the gas is sampled with the light, and thus the information from the microwave, via the gas, is transferred to the light. The difference in wavelength between microwaves and light is as much as 50,000. Sending a signal between them is not easy, but they proved, and they succeeded.
