UCLA researchers report that adding arginine to tantalum disulfide makes its charge density wave state appear at up to 135°F, up from roughly -135°F. The result is a materials-science finding, not a working device, and the path to energy-efficient quantum memory is still speculative. For quantum readers, the useful signal is that a higher-temperature quantum material is easier to study and engineer, but it still needs independent replication and device-level testing.
UCLA team finds amino acid boosts quantum properties in a material
UCLA research extends the unusual behavior of tantalum disulfide, known as the commensurate charge density wave (CCDW), to 135°F using arginine.
Starting at 135 degrees below zero Fahrenheit, a temperature nearing the record low in Antarctica, researchers at UCLA discovered an unexpected way to extend quantum properties to temperatures well above room temperature. The team found that adding the amino acid arginine to tantalum disulfide enabled the material to exhibit a commensurate charge density wave (CCDW) at temperatures as high as 135 degrees Fahrenheit. This structural arrangement,…
