Today, a major breakthrough in quantum computing technology was announced. Scientists have developed a cryogenic on-wafer prober which can be used to test the quality of a qubit. This breakthrough could revolutionize the way we test the quality of qubits, the building blocks of quantum computing. The cryogenic on-wafer prober operates at very low temperatures in order to accurately measure the quality of the qubits. This breakthrough could significantly reduce the time and resources required to test qubits, paving the way for more efficient and accurate quantum computing.
