Record number of quantum bits per processor

What you should know about this indicator

This list contains quantum processors, also known as quantum processing units (QPUs). Some devices listed have only been announced at press conferences so far, with no actual demonstrations or scientific publications characterizing the performance.

Quantum processors are difficult to compare due to the different architectures and approaches. Due to this, published qubit numbers do not reflect the performance levels of the processor. This is instead achieved through benchmarking metrics such as quantum volume, randomized benchmarking or circuit layer operations per second (CLOPS).

These QPUs are based on the quantum circuit and quantum logic gate-based model of computing.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
