U.S. scientists confirm that quantum radios can help groundwater communication and mapping

<

China National Instruments Network Instrumentation Research and Development Scientists at the National Institute of Standards and Technology (NIST) have confirmed that quantum radio can be implemented in places where GPS, ordinary mobile phones, radio information are difficult to reach, or even completely inaccessible (such as canyons, underwater, and underground). Communication and mapping. When GPS signals are difficult to penetrate water, soil, building walls, or skyscrapers, which are difficult to use in submarines, mine clearance, military or disaster relief, and radio signals are obstructed in a chaotic environment caused by rubble or electromagnetic interference, this technique can be Sailors, soldiers, and surveyors provide technical support.

NIST scientists are experimenting with a low-frequency magnetic radio—an ultra-low frequency (VLF) digitally modulated magnetic signal. Unlike traditional electromagnetic communication signals, the radio can penetrate building materials, water, and soil at higher frequencies. Ultra-low frequency electromagnetic fields have been used in underwater communications, but audio or video data transmission capabilities are limited, and can only transmit one-way text, submarines must also drag tedious wireless cables, slow down and rise to the depth of periscope (18 meters Or about 60 feet below ground to communicate. The biggest problem with low frequency communications is that the receiver sensitivity is low and the bandwidth of existing transmitters is limited, resulting in low data transmission rates. Using quantum sensors will give you the best magnetic field sensitivity and longer communication range, and it will also provide the possibility of high-bandwidth communications like cell phones. NIST scientists rely on the quantum properties of rubidium atoms to make magnetic field sensors to detect digitally modulated magnetic signals and to modulate or control the frequency by changing the magnetic field, especially the horizontal and vertical signal waveforms produced by atoms. The next step is for scientists to develop improved transmitters.
NIST has developed a dc magnetometer that uses polarized light as a detector to monitor the “autobiographical” of deuterium atoms caused by a magnetic field. In addition to its high sensitivity, the magnetometer also features room temperature operation, small size, low power consumption, low cost, low interference, and does not require movement or calibration. Next, NIST plans to build and test a custom quantum magnetometer that resembles an atomic clock. The magnetometer will monitor the signal by switching between the internal energy levels of atoms and other characteristics, and increase the range of low frequency magnetic field signals by increasing the sensitivity of the sensor. To better suppress noise, increase and effectively use the sensor's bandwidth.
The results were published in the December 2017 issue of "Review of Scientific Instruments."
