Quantummatter
Quantummatter is a term used in physics to describe states of matter in which quantum mechanical effects are the dominant organizing principle at macroscopic or mesoscopic scales. In quantummatter, properties arise from coherence, superposition, entanglement, and quantized excitations that persist beyond the single-particle level under carefully controlled conditions such as low temperature and isolation from the environment.
Realizations of quantummatter include ultracold atomic gases in optical lattices, superconductors and superfluids, Bose-Einstein condensates, exciton-polariton
Theoretical approaches to quantummatter rely on quantum many-body theory, statistics for bosons and fermions, and models
Research directions focus on quantum simulation of difficult materials, development of quantum computing platforms, and advances
Challenges include decoherence from environmental coupling, material disorder, and scaling entangled states to practical devices. Ongoing
