Absolutely maximally entangled states of seven qubits do not exist
Pure multiparticle quantum states are called absolutely maximally entangled if all reduced
states obtained by tracing out at least half of the particles are maximally mixed. We provide a …

Generalized concurrence measure for faithful quantification of multiparticle pure state entanglement using Lagrange's identity and wedge product
VS Bhaskara, PK Panigrahi - Quantum Information Processing, 2017 - Springer
Concurrence, introduced by Hill and Wootters (Phys Rev Lett 78: 5022, 1997), provides an
important measure of entanglement for a general pair of qubits that is faithful: strictly positive …

Multi-directional unitarity and maximal entanglement in spatially symmetric quantum states
We consider dual unitary operators and their multi-leg generalizations that have appeared at
various places in the literature. These objects can be related to multi-party quantum states …
