Cryogenics in Quantum Computing 

Advancements in cryogenics are enabling new class of quantum and nanotechnology applications. Quantum applications will be dependent on modular platforms that can probe and manipulate matter at the nanoscale under magnetic field and/or at low temperatures and simpler to use and manage. These environments will be used to assemble, align and analyse functional, organic or inorganic, nano‐ and microstructures, and to probe their structures, properties and dynamics, with potential applications in quantum technologies, nano based technologies, and nano-electronics.

Quantum computing has potential to impact us in so many ways and promises machines that are much faster than today’s computers with the additional ability to solve extremely complex problems that modern day supercomputers just cannot solve. Quantum computers consist of a quantum processor – sets of quantum bits or qubits. Some of the promising candidates are the superconducting qubits operating at an extremely low temperature. Quantum computers must ideally operate under a high vacuum and ultra-stable mechanical and thermal environments to prevent the unwanted excitation of the qubit state; cryogenic conditions are required because thermal energy can excite vibrational motion that could disturb quantum computing operations.

This talk presents an overview on the progress in development of advanced cryogenic environments for quantum technologies including quantum information processing. The new systems are compact in size and together with Cryofree® technology, sample management and advanced instrumentation have opened a new era in quantum and nanotechnology applications.
