For nearly 25 years, miniaturized electrical circuits cooled to extremely low temperatures have become some of the most important players in quantum technology. Invented in research laboratories, these circuits are now used as basic components (quantum bits) in prototype quantum computers developed by companies such as IBM and Google. Alongside these developments seeking to apply quantum physics, fundamental research continues using these superconducting circuits as tools for exploring the quantum world.
The work of the QCMX team, and in particular that conducted by Hannes Riechert during his PhD, has just demonstrated a new architecture for a superconducting quantum circuit associated with a carbon nanotube, which functions as a quantum bit. This is a first. The article is published in Nature Communications.
