<p>➀ A team of physicists at the Institute of Science and Technology Austria (ISTA) has successfully achieved the complete optical reading of superconducting qubits, overcoming current technological limitations. Their results have been published in Nature Physics.</p><p>➁ The research team, led by Professor Johannes Fink, has reduced the amount of cryogenic hardware needed for measurement, which could enable the increase in the number of qubits for useful calculations.</p><p>➂ The technology could lead to the construction of a network of superconducting quantum computers connected by optical fibers at room temperature, potentially overcoming current infrastructure limitations.</p>
