Abstract: Entanglement is one of the key feature of quantum world that has no classicalcounterpart. This arises due to the linear superposition principle and thetensor product structure of the Hilbert space when we deal with multiparticlesystems. In this paper, we will introduce the notion of entanglement forquantum systems that are governed by non-Hermitian yet PT-symmetricHamiltonians. We will show that maximally entangled states in usual quantumtheory behave like non-maximally entangled states in PT-symmetric quantumtheory. Furthermore, we will show how to create entanglement between twoPTQubits using non-Hermitian Hamiltonians and discuss the entangling capabilityof such interaction Hamiltonians that are non-Hermitian in nature.
