The Center Nanoelectronic Technologies (CNT) at the Fraunhofer IPMS has recently acquired new cryostats for researching qubits and qualifying superconductor systems. These low-temperature measurement devices, particularly useful for analyzing quantum systems, have been fully operational since March. The facilities were supported by the Saxony State Ministry of Science, Culture, and Tourism.

Quantum computing is expected to play a central role in research in the future, especially in medicine, material development, and traffic planning. Qubits, storage components for developing complex quantum mechanical systems, are versatile but fragile and prone to errors. Superconducting chips or circuits stabilize the fragile qubit states but require cooling down to the millikelvin range.

To ultimately realize a complex system like a quantum computer, all other technical components, such as circuits, memory chips, or thermal isolation components, must also function under these temperatures. The cryostats at CNT enable testing of various structures, materials, and circuits under these extremely cold conditions.

Microsoft has shared an update on its Majorana 1 quantum computer, which uses a topological qubit for speed, compactness, reliability, and controllability. The company aims to scale this technology for large qubit quantities, potentially ushering in an age of quantum computing.

Majorana 1 is named after Ettore Majorana, who theorized particles that are their own antiparticles. Microsoft's qubit focuses on harnessing this property. While not yet at a million qubit supercomputer, Majorana 1 is a significant step towards that goal.

The challenge now is the speed of scaling. If Microsoft can scale to one million qubits quickly, it could lead to practical quantum computing. Otherwise, it may be another decade before we see the promise of quantum computing realized.
