Scientists have discovered that a "single atomic defect" in a layered 2D material can hold onto quantum ... is an ultra-thin ...

One way around this problem is to replace silicon with graphene-like 2D materials that maintain their semiconducting properties even at a single-atom scale. Another way is building 3D chips ...

Additionally, a six-level inverted-Y scheme has been proposed to improve the precision of two-dimensional and three-dimensional atom localization. This model demonstrates that the presence of ...
