Scientists have discovered that a single defect in a 2D material, hexagonal boron nitride (hBN), can retain quantum information for a surprising length of time at room temperature. This spin coherence property allows for the storage of quantum information for approximately 1 millionth of a second, without the need for special conditions or large magnets. Manipulating electron spins within these defects using light at room temperature is groundbreaking. The findings, published in Nature Materials, confirm the potential of 2D materials in advancing quantum technologies and highlight the power of investigating new materials for future applications.
