Environment-assisted squeezing in a coherently driven non-Hermitian degenerate parametric oscillator
Muhdin Abdo Wodedo, Berihu Teklu, Konstantin G. Zloshchastiev +2
Environment-assisted approaches to nonclassical light offer a practical path to strong squeezing in imperfect, lossy platforms. In this paper, we study a degenerate parametric osci…
Influence of quantum decoherence on the survival of quantumness in neutrino oscillations
Jilali Loulijat, Abdallah Slaoui, Mohamed Gouighri +1
This study examines the dynamics of quantumness in two-flavor neutrino oscillations subjected to a dephasing channel, using representative oscillation parameters associated with th…
Nonlinearity and Quantum Metrology in the Double-Morse Potential
Firoz Chogle, Berihu Teklu, Jorge Zubelli +1
We address the nonlinear properties of the double-Morse potential as a resource for single-mode quantum states due to its double-well structure and anharmonicity. We obtain analyti…
Stroboscopic Saturation of Multiparameter Quantum Limits in Distributed Quantum Sensing
Berihu Teklu, Victor Montenegro
High-precision sensors that exploit uniquely quantum phenomena have been shown to surpass the standard quantum limit of measurement precision. However, in the general scenario wher…
Amplifying Two-Mode Squeezing in Nanomechanical Resonators
Muhdin Abdo Wodedo, Tesfay Gebremariam Tesfahannes, Tewodros Yirgashewa Darge +2
Quantum squeezing plays a crucial role in enhancing the precision of quantum metrology and improving the efficiency of quantum information processing protocols. We thus propose a s…
Optimizing mechanical entanglement using squeezing and parametric amplification
Muhdin Abdo Wodedo, Tesfay Gebremariam Tesfahannes, Tewodros Yirgashewa Darge +1
We propose a scheme of an optomechanical system that optimizes entanglement in nanomechanical resonators through quantum state transfer of intracavity squeezing and squeezed reserv…
