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…
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…
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…
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…
Sub-Planck structures and sensitivity of the superposed photon-added or photon-subtracted squeezed-vacuum states
Naeem Akhtar, Jizhou Wu, Jia-Xin Peng +2
The Wigner function of the compass state (a superposition of four coherent states) develops phase-space structures of dimension much less than the Planck scale, which are crucial i…
