- Effects of intrinsic decoherence in multipartite system subjected to Kerr effect and parametric amplification with quantum correlations and estimation (2026) · Modern Physics Letters A · doi
The vulnerability of entanglement to external noise is a significant barrier to creating reliable quantum devices. There is a need to understand the interplay between quantum correlations and quantum Fisher information. The effects of system's Hilbert space dimensionality on the correlation dynamics and parameter estimation precision are not well understood.
