Quantum Technology Toolbox - your pocket lab assistant. Quantum Technology Toolbox is a calculator for calculating the oh-so-ubiquitous interferometric visibility with a few simple button presses. How many times haven't we fiddled with regular calculators, trying to remember intermediary values when working in the lab? The solution to this cumbersome calculation is here with your own pocket visibility measurement data bank. In QTT you can compute, store and organise your visibility measurements into collections. A single click allows you to filter values, and export them to csv. This allows you to easily keep track of your experiment's progress while aligning the experiment.
