pyRegkey

python script for save and load {key:value} data with customized units,

and a data vault for saving experimental data.

Introduction

This codes provide the inter-conversion of dictionary (.dict) and a series of file with specific extension (e.g. .key).

For example, a python dictionary for the experimental parameters,

paras = {'num':410,'f10': Value(5.623,'GHz'), 'type': 'transmon', 'xlist': [0.8, 1.2, 1.5]}

Here, we can get individual files num.key, f10.key, type.key, xlist.key, where the contents are the values of dictionary.

Registry

mainly in regkey.py, and import some codes in util

sub-directory

You can access the sub-directory via folder['sub_folder']['sub_sub_folder'] or folder.sub_folder.sub_sub_folder, to change any key in the main Registry folder.

folder.sub_folder.sub_sub_folder.key0 = value0
# or
folder['sub_folder']['sub_sub_folder']['key0'] = value0

We usually have a structure Registry\\User.dir\\20XXXXSample.dir\\q1.dir , and use

sample, qubits = loadQubits(write_access=False).

Specially, sample['q1'].f10 = 5.414*GHz will change the original .key, qubits is a copy and qubits[0]=5.414*GHz will not change the saved file.

basic types

All the types in python expression are supported

# float/int
11.0,-45.0,1,-4 

# string
'ikuiku' 

# list
[1.14,5.14,1.5,1.5] 
[('xy','12','13'),('z','12','13')]

# ...

Unit

You can write 11.4514*GHz or Value(11.4514,'GHz') to define a number with units.

Transformation of the usual units are supported, for example,

Value(11.4514,'GHz')['MHz']=11451.4

Combined type is also okay

"""[1.2 ns, 1.3 ns]""" in the saved file .key --> [Value(1.2,'ns'),Value(1.3,'ns')] in the extracted .dict

write_access

You can change the value in RegistryWrapper() as paras.f10 = 5.414*GHz , then the original file is also changed.

If you do not want to change the original file, you can use a copy of paras.

DataVault

mainly in dataVault.py, and import some codes in util

• Example:

run dataVault in ipython

and input

path = ['XXX','Ziyu','peach']
ctx = init_context(path)
dv = DataVault()

import numpy as np
xs = np.arange(0.,101,1)
ys = np.sin(0.1*xs)

dv.new(ctx,'Test_x_y22', [('freq', 'value')], [('z','Test-Spectrum','a.u.')])
dv.add_parameter(ctx,'simu_eq22', ['ys=sin(xs)'])

import time

for i in range(len(xs)):
    
    x,y=xs[i],ys[i]
    print(i)
    data = [x,y]
    data = np.asarray(data)
    
    dv.add(ctx,data)
    time.sleep(0.001)
   
dv.close(ctx)

TODO

UI interface for the key editing

now we still use Registry.exe, Grapher.exe from labrad (ucsb) as a temporal solution
