Quantum computers are expected to surpass modern current computers in certain types of computations by utilizing quantum mechanical properties of atoms, molecules, and photons. Quantum computers are attracting attention for their ability to process huge amounts of data at high speeds by utilizing the superposition state of quantum bits, a property of quantum mechanics, which enables parallel calculations. Quantum computers are expected to lead to the development of: New drug development, New material development, Finance of investment portfolio optimization, Logistics of optimizing delivery routes, Disaster response of Predicting damage during disasters, and so on.
Because the signals from the qubits of a superconducting quantum computer are extremely weak, a low-temperature receiver configuration is required to avoid the effects of thermal noise. Therefore, the microwave components for the superconducting quantum computer must be measured in a low-temperature environment. I introduce the cryogenic testbed system developed by AIST. In particular, we will focus on the thermal insulating transmission line technology and introduce examples of application of this technology to cryogenic testbed systems.
