• Title: Influence of squeezing on the weak-to-strong measurement transition
• Authors: Kevin Araya-Sossa and Miguel Orszag
• Abstract summary: We show that the shift in the pointer's position and momentum establishes a relationship with a new value defined as the transition value. A new strategy is introduced to achieve different measurement regimes by just adjusting the parameters of the coherent squeezed pointer state. Our scheme has been theoretically applied in a trapped ion illuminated by a bichromatic laser beam, with a high potential to be implemented in future setups.

• Abstract: In this work, we study the measurement transition for a coherent squeezed pointer state through a transition factor $\Gamma$ that involves a system-pointer coupling by using an arbitrary measured observable $A$. In addition, we show that the shift in the pointer's position and momentum establishes a relationship with a new value defined as the transition value, which generalizes the weak value as well as the conditional expectaction value. Furthermore, a new strategy is introduced to achieve different measurement regimes by just adjusting the $r$ and $\phi_{\xi}$ parameters of the coherent squeezed pointer state, opening an interesting way to test quantum mechanics foundations. Our scheme has been theoretically applied in a trapped ion illuminated by a bichromatic laser beam, with a high potential to be implemented in future experimental setups.

In addition to the sheer liberation of experimental expense, the photon-countering-based pointer is well-calibrated for the detection of weak signals.

  We make measurement-induced phase transitions observable using pre-selection scheme. The steering can be chosen so gently that the basic properties of the underlying transition, such as entanglement structure and critical exponents, are not modified. This insight further enables a quantum simulation strategy, determining the underlying class in state-of-the-art quantum platforms without measurement readout.
