In the modern formalism introduced by Dirac, all quantum states are represented by objects called kets in an infinite-dimensional Hilbert space. A ket is an abstract complex vector associated with a wave function and therefore with a physical state of a particle, a photon, or any microscopic quantum object. Here begins the exploration of the arsenal of quantum mechanics. #ket #autoket #states #quantummechanics #physics #mathematics #hilbert #spacevector #quantum #geometry #mathematics #linearalgebra #linearalgebra #vectors #matrix #operators #quantumstates #vectors #dirac
