modified on 2018-08-27, 14:53 This zip contains the data sets of free space optical transmission conducted from 10:00 on 7 Jun. 2017 to 10:35 on 13 Jun. 2017. See Fig. 10 in our companion paper ``Free space optical secret key agreement".
A data of one frame consists of following four rows with the same FrameIDs.
The 1st row (IsBob = 1, Is1 = 1) shows Bob's histogram when Alice sent bit `1'.
The 2nd row (IsBob = 1, Is1 = 0) shows Bob's histogram when Alice sent bit `0'.
The 3rd row (IsBob = 0, Is1 = 1) shows Eve's histogram when Alice sent bit `1'.
The 4th row (IsBob = 0, Is1 = 0) shows Eve's histogram when Alice sent bit `0'.
Column 1, `FrameID': A unique number to identify the frame, written as `yyyymmdd_hhnnss_XXXX_?';
`yyyy': year,
`mm': month,
`dd': day,
`hh': hour,
`nn': minute,
`ss': second,
`?': A to K (additional character to identify frames acquired at the same time).
Column 2, `IsBob': Indicator to identify the receiver;
`1': Bob,
`0': Eve.
Column 3, `Is1': Indicator to identify the Bit sent by Alice;
`1': Alice sent bit `1',
`0': Alice sent bit `0'.
Column 4, `BobPower': Average received signal power at Bob [nW].
Column 5, `EvePower': Average received signal power at Eve [nW].
Column 6, `KeyRate': Final key rate [kbps].
Column 7, `rank_m50' to Column 307, `rank_p248':
Frequency distribution of detector output divided into -50 to 250 values;
e.g., Column 8, `rank_m49' shows the number of data greater than or equal to -49 but smaller than -48.
