quantum system
portion of the whole universe (environment or physical world) which is taken under consideration to make analysis or to study for quantum physics pertaining to the wave-particle duality in that system and everything else than this system
particle in a spherically symmetric potential
quantum mechanical model of a quantum nonrelativistic particle subject to a classical spherically symmetric potential well
spin chain
model in quantum statistical physics consisting of a graph with a spin attached to each vertex and with interactions given by the graph topology
quantum computer
computational device relying on quantum mechanics
open quantum system
quantum mechanical system that interacts with a quantum-mechanical environment
time crystal
quantum system whose ground state is one in which the particles are in repetitive motion
two-state quantum system
quantum system that can exist in any quantum superposition of two independent (physically distinguishable) quantum states; quantum systems with two possible states
