The University of Washington has developed boron nitride-based quantum sensors<\/strong> that can endure pressure 30,000 times that of the Earth’s atmosphere. The new technology may revolutionize high-pressure physics<\/strong>.<\/p>\n\n\n\n

Despite recent advances in quantum technologies<\/a><\/em><\/strong>, one of the biggest problems in the field remains unresolved: reliably measuring quantum behavior<\/strong> under extreme pressure<\/strong>. Research has been significantly limited until now because sensors used previously could not withstand these conditions. However, a new study led by the University of Washington<\/strong> points to a development that could radically change this situation. Researchers announced that new quantum sensors<\/strong> made from boron nitride<\/strong> can withstand pressures up to 30 GPa<\/strong> (30,000 times the Earth’s atmosphere).<\/p>\n\n\n\n

According to the study published in Nature Communications<\/strong>, these sensors can measure the magnetic field<\/strong>, stress, and other physical changes in materials exposed to extreme pressure with quantum sensitivity<\/strong>. This technology is seen as a groundbreaking step, both in understanding the behavior of matter under high pressure<\/strong> and in the development of new quantum devices<\/strong>.<\/p>\n\n\n\n

The Limit of Diamond Sensors Surpassed: The Solution is 2D Boron Nitride<\/h2>\n\n\n\n

The research team had previously developed similar quantum sensors by creating atomic vacancies within diamond crystals<\/strong>. However, the three-dimensional structure of diamonds limited the accuracy of measurements by creating a distance between the sensor and the material being studied. The new method eliminates this disadvantage.<\/p>\n\n\n\n

Scientists created controlled vacancies by bombarding layers of hexagonal boron nitride (hBN)<\/strong>, which are only a few atoms thick, with a neutron beam<\/strong>. The resulting atomic vacancies<\/strong> convert electron spins<\/strong> into a measurable quantum signal. Thanks to the sensor’s two-dimensional structure<\/strong>, the distance between the sensor and the material being studied can be reduced to less than a nanometer<\/strong>. This provides a significant advantage compared to diamond-based sensors.<\/p>\n\n\n\n

Despite this, the diamond<\/strong> still plays a key role in the system. Researchers use a diamond anvil cell<\/strong>, consisting of two diamond surfaces, to generate the high pressure. The boron nitride sensors<\/strong> placed inside this setup make it possible to operate at pressure levels that no quantum measuring device has previously been able to withstand.<\/p>\n\n\n\n
