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 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…
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…
Single-photon-added coherent state based postselected weak measurement
Yi-Fang Ren, Yusuf Turek
We investigated precision measurements in a two-level system coupled to a single-photon-added coherent state (SPACS) under postselection measurement. We analyzed strategies for imp…
