Programmable optical parametric amplifier synthesizer for cubic phase states and amplified Schrodinger cat states
Yusuf Turek, Ming-Yan Sun, Xiao-Xi Yao
We introduce a programmable optical parametric amplifier (OPA) synthesizer that, under a heralded photon-number-resolving framework, generates high-fidelity cubic phase states and…
Multiphoton heralding generates large-amplitude squeezed Schrödinger cat states and parity-selective Fock superpositions from squeezed vacuum via an OPA
Yusuf Turek, Ming-Yan Sun, Xiao-Xi Yao
We propose a multiphoton heralding scheme using an optical parametric amplifier (OPA) that converts squeezed vacuum into two families of non-Gaussian states: large-amplitude squeez…
Non-Gaussian Quantum State Engineering with Postselected von Neumann Measurements
Xiao-Xi Yao, Yusuf Turek
We introduce a feasible protocol for generating non-Gaussian (nG) states via postselected von Neumann measurement for continuous-variable quantum information processing. The method…
Quantum-Classical Boundary Engineering in Weak-to-Strong Measurements via Squeezed Vacua
Janarbek Yuanbek, Wen-Long Ma, Yusuf Turek
This study establishes a post-selected von Neumann framework to regulate non-classical features of single-photon-subtracted squeezed vacuum (SPSSV) and two-mode squeezed vacuum (TM…
Non-Gaussian state preparation and enhancement using weak-value amplification
Xiao-Xi Yao, Yusuf Turek
We introduce a protocol for generating a broad class of non-Gaussian (nG) quantum states via postselected weak measurement techniques. The scheme involves injecting an arbitrary qu…
Effects of driven atomic ensemble on the output spectrum and entanglement of optomechanical system
Burabigul Yakup, Yi-Fang Ren, Mamat Ali Bake +1
This paper considers an indirect driving model of a cavity QED system in which the left cavity wall consists of a large ensemble of two-level atoms driven by a classical laser fiel…
