Dataset for Phys. Rev. Lett. 126, 170601 : Information and thermodynamics : fast and precise approach to Landauer's bound in an underdamped micro-mechanical oscillator

1) 'Figure4.fig', 'Figure5.fig', 'FigureS4.fig', 'FigureS5.fig' and 'FigureS6.fig' - Matlab Figures

Those Matlab figures correspond to the ones in the related PRL article.

2) 'Script_analysis.m' and 'Initialisation_arrays.m' - Matlab Scripts

These scripts are written in matlab language to analyse the data provided in this datasheet (Initialisation_arrays being a subfunction called by the main script). It conducts a basic analysis that takes as input the voltage arrays from the experiment and outputs the dimensionless quantities mentionned in the article : z, z0, z1, dW, dQ, W, Q. The comments and figures plotted by the script are meant to help the understanding.

3) 'protocol1_01.mat' to 'protocol1_1000.mat - Matlab files

Data corresponding to 1000 erasures protocols of parameter \(\tau=50 ms\). (Using the notations of the article)

Each file is in Matlab format and contains all the data from the experiment. For the analysis, we need in particular :

'dt' : the time discretisation,

'tau' : the steps duration,

'Sx' : the voltage corresponding to the position of the cantilever from the photodiodes,

'Sx0' : the driving voltage that controls the position of the potential barrier,

'Vs'  : the driving voltage that controls the ditance between the centers of the potential wells.

4) 'protocol2_01.mat' to 'protocol2_2000.mat - Matlab files

Data corresponding to 2000 erasures protocols of parameter \(\tau=5 ms\). (Corresponding to the Figure S3 of the article)

5) 'slow_erasure_01.mat' to 'slow_erasure_2000.mat - Matlab files

Data corresponding to 2000 erasures protocols of parameter \(\tau=200 ms\). (Corresponding to the Figure 3 of the article)

1) 'Figure4.fig', 'Figure5.fig', 'FigureS4.fig', 'FigureS5.fig' 与 'FigureS6.fig' —— Matlab 图形文件
上述Matlab图形文件与相关《物理评论快报》（PRL）论文中的配图完全对应。

2) 'Script_analysis.m' 与 'Initialisation_arrays.m' —— Matlab 脚本文件
此类脚本采用Matlab语言编写，用于分析本数据集提供的实验数据，其中Initialisation_arrays为供主脚本调用的子函数。该基础分析程序以实验获取的电压数组作为输入，输出论文中提及的无量纲量：z、z0、z1、dW、dQ、W与Q。脚本内置的注释与生成的绘图内容可辅助读者理解分析逻辑。

3) 'protocol1_01.mat' 至 'protocol1_1000.mat' —— Matlab 数据文件
该批数据对应1000组参数为τ=50 ms的擦除协议实验（采用论文中的符号体系）。
每个文件均为Matlab格式，存储了单次实验的全部数据。分析所需的核心数据字段包括：
'dt'：时间离散步长，
'tau'：单步时长，
'Sx'：光电二极管采集的悬臂位置对应电压，
'Sx0'：控制势垒位置的驱动电压，
'Vs'：控制势阱中心间距的驱动电压。

4) 'protocol2_01.mat' 至 'protocol2_2000.mat' —— Matlab 数据文件
该批数据对应2000组参数为τ=5 ms的擦除协议实验（对应论文中的补充图S3）。

5) 'slow_erasure_01.mat' 至 'slow_erasure_2000.mat' —— Matlab 数据文件
该批数据对应2000组参数为τ=200 ms的擦除协议实验（对应论文中的图3）。
