The fractional quantum anomalous Hall effect (FQAHE) offers a promising path toward universal topological quantum computation by hosting non-Abelian Fibonacci anyonic parafermions. Recent breakthroughs in twisted bilayer MoTe2 and rhombohedral multilayer graphene/hBN moiré superlattices have demonstrated fractionally quantized states, paving the way for high-filling fractions and fractional topological superconductivity, both of which are potential foundations for parafermions. Challenges remain in generalizing the required exotic states and integrating superconductivity, but FQAHE could be a key solution to the universality of topological quantum computation.
NIST researchers have developed a new mathematical formula to calculate the concentration of particles suspended within a solution. This new approach is more accurate than current methods because it correctly accounts for variation in particle size. The new method will be useful in various fields, including nanomedicine, food science, environmental science and advanced manufacturing.
SUTD researchers have developed a new class of algorithms that enable low-latency, real-time computing and data transmission in large-scale satellite networks, which could lead to smarter, faster global connectivity.
That fit people have a reduced risk of premature death from various diseases is a recurring result in many studies. New research from Uppsala University shows that people with high fitness levels in their late teens also have a reduced risk of dying from random accidents. This suggests that the associations seen in previous studies have probably been misleading.
