An advanced computational tool for understanding quantum materials
Ball and stick representation of the atoms in a crystal with a spin defect in the center, and the three-dimensional surfaces (red and blue) showing the excited states of the…
Researchers take a different approach with measurement-based quantum computing
Atsushi Sakaguchi and his team are exploring the possibility of using light to produce quantum computers that are measurement based rather than gate based. Credit: RIKEN The race to develop…
Why string theory requires extra dimensions
Superstrings may exist in 11 dimensions at once. Credit: National Institute of Technology Tiruchirappalli String theory found its origins in an attempt to understand the nascent experiments revealing the strong…
New strategy reveals ‘full chemical complexity’ of quantum decoherence
Rochester researchers have reported a strategy to understand how quantum coherence is lost for molecules in solvent with full chemical complexity. The findings open the door to the rational modulation…
