Page curve under final state projection
نویسندگان
چکیده
The black hole singularity plays a crucial role in formulating Hawking's information paradox. global spacetime analysis may be reconciled with unitarity by imposing final state boundary condition on the spacelike singularity. Motivated proposal, we explore effect of projection two dimensional conformal field theories. We calculate time evolution under postselection employing real part pseudoentropy to estimate amount quantum entanglement averaged over histories between initial and states. find that this quantity possesses Page-curve-like behavior.

Prophecy: Accelerating Mobile Page Loads Using Final-state Write Logs
Web browsing on mobile devices is expensive in terms of battery drainage and bandwidth consumption. Mobile pages also frequently suffer from long load times due to high-latency cellular connections. In this paper, we introduce Prophecy, a new acceleration technology for mobile pages. Prophecy simultaneously reduces energy costs, bandwidth consumption, and page load times. In Prophecy, web serve...
متن کاملBlack hole evaporation in a thermalized final-state projection model
We propose a modified version of the Horowitz-Maldacena final-state boundary condition based upon a matter-radiation thermalization hypothesis on the Black Hole interior, which translates into a particular entangled state with thermal Schmidt coefficients. We investigate the consequences of this proposal for matter entering the horizon, as described by a Canonical density matrix characterized b...
متن کاملUnitarity of black hole evaporation in final-state projection models
Almheiri et al. have emphasized that otherwise reasonable beliefs about black hole evaporation are incompatible with the monogamy of quantum entanglement, a general property of quantum mechanics. We investigate the final-state projection model of black hole evaporation proposed by Horowitz and Maldacena, pointing out that this model admits cloning of quantum states and polygamous entanglement, ...

This paper demonstrates the chemical sensing capability of a miniaturized fiber inline Fabry-Pérot sensor fabricated by femtosecond laser. Its accessible cavity enables the device to measure the refractive index within the cavity. The refractive index change introduced by changing the acetone solution concentration was experimentally detected with an error less than 4.2×10.
متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
