Decoherence across phase-space scales: From compass states to general quantum states
Naeem Akhtar, Jia-Xin Peng, Tan Hailin +2
Environmental decoherence occurs when a quantum system interacts with its surroundings, progressively reducing quantum interference and coherence, complicating the preservation of…
Sub-shot-noise sensitivity via superpositions of two deformed kitten states
Naeem Akhtar, Xiaosen Yang, Jia-Xin Peng +3
In the present work we explore nonclassical effects in the phase space of two superposed kitten states induced by photon addition and subtraction operations applied in different se…
Enhancement in temperature sensing of a reservoir by Kerr-nonlinear resonator
Naeem Akhtar, Jia-Xin Peng, Xiaosen Yang +1
The challenge of developing high-precision temperature sensors is an important issue that has recently received a lot of attention. In this work, we introduce an estimation techniq…
Compasslike states in a thermal reservoir and fragility of their nonclassical features
Naeem Akhtar, Xiaosen Yang, Muhammad Asjad +3
Superposed photon-added and photon-subtracted squeezed-vacuum states exhibit sub-Planck phase-space structures and metrological potential similar to the original compass states (su…
