SU(2) Invariants of Symmetric Qubit States
Swarnamala Sirsi, Veena Adiga
Density matrix for N-qubit symmetric state or spin-j state (j = N/2) is expressed in terms of the well known Fano statistical tensor parameters. Employing the multiaxial representa…

Entangling capabilities of Symmetric two qubit gates
Swarnamala Sirsi, Veena Adiga, Subramanya Hegde
Our work addresses the problem of generating maximally entangled two spin-1/2 (qubit) symmetric states using NMR, NQR, Lipkin-Meshkov-Glick Hamiltonians. Time evolution of such Ham…
