Quantum technologies are emerging fast with a strong urge for adaptation across a wide range of applications, including security, defense, life-science, pharmaceuticals, material science, and logistics.
While quantum sensing and communication are already being adopted for real-world applications, considerable technology maturation is still needed to reach full utility-scale for quantum computing. That forces us to ask ourselves, “What will it take to truly functionalize quantum technologies?”, where standardization of how components and subsystems integrate will play a crucial role.
Manipulating physical phenomena at the atomic level of matter means obeying the laws of quantum physics, these laws are constantly challenged because of new discoveries being brought forward, but at the same time the fundamental laws allow for practical applications, i.e. building quantum processing units. These units are the main building blocks in quantum computers, where qubits are the information carriers, i.e. a system with quantized degrees of freedom, enabling encoding and decoding of information using addressable quantum states. The information carrier signal path and the control signal paths travels from temperatures close to 0 K and up to 300 K and vice versa.
This document addresses the proper design and implementation of the cryogenic-to-room-temperature travel with a special emphasis on interfaces between the different temperature stages in quantum computers.
