Archer Materials Limited, a semiconductor company focused on quantum technology, has made recent strides in the development of its 12CQ quantum chip. According to their latest announcement, Archer has successfully produced two proof-of-concept devices designed to enhance the spin detection capabilities of the chip, relevant to integrating quantum computing with mobile devices.

Together with 24 German research institutions and companies under the coordination of Forschungszentrum (FZ) Jülich, Fraunhofer IPMS is working on an integrated German quantum computer based on superconducting quantum chips and with improved error rates. Halfway through the project, the first demonstrator can now be put into operation.

A collaborative research team led by Prof. Junwei Liu, Associate Professor in the Department of Physics at the Hong Kong University of Science and Technology (HKUST), and Prof Jinfeng Jia and Prof Yaoyi Li from Shanghai Jiao Tong University (SJTU), has identified the world’s first multiple Majorana zero modes (MZMs) in a single vortex of the superconducting topological crystalline insulator SnTe and exploited crystal symmetry to control the coupling between the MZMs.

This study shows that the superconducting edge currents in the topological material molybdenum telluride (MoTe2) can sustain big changes in the “glue” that keeps the superconducting electrons paired. This is important because electrons pairing up is what makes electricity flow freely in a superconductor.

OrangeQS supports Aalto University in building a test bench for few-qubit QPU testing within the European project OpenSuperQPlus. Part of this test bench is an OrangeQS Rack, which was delivered this week to Helsinki. What is special about this delivery is a new back-end for the open-source platform Quantify. This back-end was developed together with Zurich Instruments within OpenSuperQPlus.

Bluefors today announced the immediate availability of a XLDHe High Power System – a cryogen-free, helium-4 powered measurement system that delivers extremely high cooling power for experiments in the 1 K temperature range. The XLDHehp is ideal for demanding applications such as spin qubit quantum computing devices, or single photon detectors for photonic quantum computers.

Amulti-institutional team of scientists in the United States, led by physicist Peng Wei at the University of California, Riverside, has developed a new superconductor material that could potentially be used in quantum computing and be a candidate “topological superconductor.”

Physicists from Aalto University in Finland, alongside an international team of collaborators, have theoretically and experimentally shown that superconducting qubit coherence loss can be directly measured as thermal dissipation in the electrical circuit holding the qubit.

Now, researchers have observed that a necessary characteristic of a superconductor – called electron pairing – occurs at much higher temperatures than previously thought, and in a material where one least expects it – an antiferromagnetic insulator. Although the material did not have zero resistance, this finding suggests researchers might be able to find ways to engineer similar materials into superconductors that operate at higher temperatures.

An MIT-led group shows how to achieve precise control over the properties of Weyl semimetals and other exotic substances.
