Abstract
Electron superlattices allow the engineer of correlated and topological quantum phenomena. The recent emergence of moiré superlattices in two-dimensional (2D) heterostructures has led to exciting quantum phenomena discoveries. However, the requirement of the moiré pattern poses stringent limitations, and its potential cannot be switched on and off. Here, we demonstrate remote engineering and on/off switching of correlated states in bilayer graphene. Employing a remote Coulomb superlattice realized by localized electrons in a twisted bilayer WS2, we impose a Coulomb superlattice in the bilayer graphene with period and strength determined by the twisted bilayer WS2. When the remote superlattice is turned off, the two-dimensional electron gas (2DEG) in the bilayer graphene is described by a Fermi liquid, when it is turned on, correlated insulating states at both integer and fractional filling factors emerge. This approach enables in-situ control of correlated quantum phenomena in 2D materials hosting a 2DEG.

Description of the data and file structure
The 'source_data.rar' archive contains a main folder named 'Raw data'. Within this main folder, there are several subfolders categorized based on the type of figures they contain:
- Main Figures: Four folders.
- Extended Data Figures: Ten folders.
- Supplementary Figures: Five folders.
Each folder is named according to the corresponding figure caption. Below is the details of each folder

Folder Structure and Content
Inside each folder, you will find text files corresponding to the subpanels of each figure. For instance, the data file for generating Figure 3c is named Figure 3c.txt.
Data Format
The format of the data files depends on the type of plot:
- Line Plots:
- The first column represents the horizontal axis (x-axis).
- The other columns represent the vertical axis (y-axis).
- Two-Dimensional Color Plots:
- The first column and the first row represent the horizontal and vertical axes, respectively.
- The remaining matrix data represents the color values for the plot.
This structured organization ensures that each figure and subpanel can be easily generated using the corresponding data files.
