Superconducting qubits passing the Bell test for the first time is expected to promote the development of quantum computing and quantum encryption technology.

[superconducting qubits pass the Bell test for the first time is expected to promote the development of quantum computing and quantum encryption technology] the Bell test can confirm whether the two systems are really entangled. In a paper published in the latest issue of the journal Nature, scientists at the Federal Institute of Technology (ETH) in Zurich say they have proved for the first time that two superconducting circuits 30 meters apart have passed a key test in this quantum field, proving that there is indeed entanglement between qubits in superconducting circuits. The researchers said that superconducting circuits are promising candidates for building powerful quantum computers, and the latest research is expected to promote the development of quantum computing and quantum encryption, and expand the scale of quantum computers based on superconducting circuits.
