Abstract:One of the most fundamental quantum states of light is the squeezed vacuum， in which noise in one of the quadratures is less than the standard quantum noise limit. In nanophotonics， it remains challenging to generate， manipulate， and measure such a quantum state with the performance required for a wide range of scalable quantum information systems. Here， we report the development of a lithium niobate–based nanophotonic platform to demonstrate the generation and all-optical measurement of squeezed states on the same chip. The generated squeezed states span more than 25 terahertz of bandwidth supporting just a few optical cycles. The measured 4.9 decibels of squeezing surpass the requirements for a wide range of quantum information systems， demonstrating a practical path toward scalable ultrafast quantum nanophotonics.

以货币层级理论重勘张居正变法：信用重构、层级失衡与财政宿命
After Zhang’s death， the core institutional framework of silver-based fiscal monetisation persisted. Hierarchical inversion remained latent during periods of abundant silver inflow but generated cascading systemic collapse once the global credit cycle tightened.

A stable perovskite heterojunction was constructed for inverted solar cells through surface sulfidation of lead –rich perovskite films. The formed lead-sulfur bonds upshifted the Fermi level at the perovskite interface and induced an extra back-surface field for electron extraction. The resulting inverted devices exhibited a power conversion efficiency >24% with a high open-circuit voltage of 1.19 volts， corresponding to a low voltage loss of 0.36 volts. The strong Pb-S bonds could stabilize perovskite heterojunctions and strengthen underlying perovskite structures that have a similar crystal lattice. Devices with surface sulfidation retained more than 90% of the initial PCE after aging at 85°C for 2200 hours or operating at the maximum power point under continuous illumination for 1000 hours at 55° ± 5°C.
