New Identity for Cayley's First Hyperdeterminant with Applications to Symmetric Tensors and Entanglement
Isaac Dobes
In this article, a new formula for computing Cayley's first hyperdeterminant in terms of the Levi-Civita symbol is given. It is then shown that this formula can be used to compute…
Cayley's First Hyperdeterminant is an Entanglement Measure
Isaac Dobes, Naihuan Jing
Previously, it was shown that both the concurrence and -tangle on -qubit pure quantum states can be expressed in terms of Cayley's first hyperdeterminant \cite{dobes2024qubi…
Classifying Density Matrices of 2 and 3 Qubit States Up To LU Equivalence
Isaac Dobes, Naihuan Jing
In this paper we present a modified version of the proof given Jing-Yang-Zhao's paper titled "Local Unitary Equivalence of Quantum States and Simultaneous Orthogonal Equivalence,"…
Local Unitary Equivalence of Tripartite Quantum States In Terms of Trace Identities
Isaac Dobes, Naihuan Jing
In this paper we present a modified version of the proof given Jing-Yang-Zhao's paper "Local Unitary Equivalence of Quantum States and Simultaneous Orthogonal Equivalence," which e…
Qubits as Hypermatrices and Entanglement
Isaac Dobes, Naihuan Jing
In this paper, we represent -qubits as hypermatrices and consider various applications to quantum entanglement. In particular, we use the higher-order singular value decompositi…
