“Superconducting qubits are solid-state electrical circuits, which can be designed with high accuracy and flexibility.”
The superconductor also releases another kind of particle into the metal, known as Andreev reflection.
The researchers looked for these Andreev reflections to detect Cooper pairs.

This approach lets them detect the amount of Andreev reflection returning to the superconductor.
One of the biggest challenges in quantum computing today relates to how we can make superconductors perform even better.
The Superconducting Future
Superconducting quantum computers currently beat rival technologies in terms of processor size, Cubittsaid.

“All quantum hardware companies have ambitious roadmaps to scale their computers in the near future,” Cubittadded.
The ‘Holy Grail’ of quantum computing is a gadget with hundreds of qubits and low error rates.
Scientists can’t agree on how they will achieve this goal, but one possible answer is using superconductors.
