Local Unitary Invariants for N-qubit Pure State
S. Shelly Sharma, N. K. Sharma
We obtain local unitary invariant polynomials for N qubit quantum state from first principles. A basic unit of entanglement, referred to as negativity font, is defined as a two by…

Quantum coherences, K-way negativities and multipartite entanglement
S. Shelly Sharma, N. K. Sharma
A characterization of N-partite states, based on K-way (K = 2 to N) negativities, is proposed. The K-way partial transpose with respect to a subsystem is defined so as to shift the…

Schrödinger cat state of trapped ions in harmonic and anharmonic oscillator traps
S. Shelly Sharma, N. K. Sharma
We examine the time evolution of a two level ion interacting with a light field in harmonic oscillator trap and in a trap with anharmonicities. The anharmonicities of the trap are…
