11 Jul 2023: Scientists at Cornell University have identified a new phase of matter called a “spin-triplet electron-pair crystal” in the superconductor Uranium Ditelluride (UTe2). This discovery could have significant consequences for condensed matter physics and for the field of quantum computing and spintronics.

06 Jul 2023: Researchers from the University of Maryland have made a significant advancement in superconducting quantum technology by creating fluxonium qubits that can retain information for 1.43 milliseconds, which is a 10x improvement compared to the previous record. This breakthrough brings fluxonium qubits back in competition with transmon qubits, the current favorite for quantum computers developed by companies like Google and IBM.

04 Jul 2023: Google has developed a quantum computer that can perform calculations in a matter of seconds that would take the most advanced supercomputers nearly 50 years to process.

03 Jul 2023: Engineers at North Carolina State University (NCSU) have discovered a new form of silicon called Q-silicon with properties that could be beneficial for quantum computers and spintronics. Q-silicon exhibits ferromagnetism at room temperature, making it suitable for data storage and potentially enabling advancements in spintronics. It also demonstrates enhanced hardness and superconductivity, which could further aid spintronics and quantum computing.

22 Jun 2023: Quantum computing, just like traditional computing, needs a way to store the information it uses and processes. On the computer you’re using right now, information, whether it be photos of your dog, a reminder about a friend’s birthday, or the words you’re typing into your browser’s address bar, has to be stored somewhere. Quantum computing, being a new field, is still working out where and how to store quantum information.

20 Jun 2023: Archer Materials Limited (“Archer”, the “Company”), a semiconductor company that advances the quantum computing and medical diagnostics industries, has achieved a significant development milestone in the functionality of its cutting-edge qubit material.​​​​​​​

19 Jun 2023: IBM is one step closer to realizing a quantum computer with true utility that can outperform classical computers in certain workloads. The technology giant recently used its Quantum “Eagle” processor with 127 superconducting qubits to create entangled states that “simulate the dynamics of spins in a model of material and accurately predict properties such as its magnetization.”

13 Jun 2023: The advent of quantum computing poses a significant threat to traditional cryptographic systems, emphasising the need for cryptography to be modernised. Migrating to post-quantum cryptography allows organisations to future-proof their security infrastructure. Significant investments in quantum technologies by various countries, as well as the inclusion of the quantum threat in key challenges, highlight the urgency, such as the United States government mandating the transition to post-quantum cryptography.

08 Jun 2023: Chinese scientists have made a significant breakthrough in quantum computing with their Jiuzhang computer, claiming it can perform AI-related tasks 180 million times faster than the world’s fastest classical supercomputer. The researchers believe this development could have applications in data mining, biological information, network analysis, and chemical modeling research.

05 Jun 2023: RIKEN scientists have made a significant advancement in quantum computing by successfully connecting two physically distant silicon spin qubits using coherent spin shuttling. This breakthrough overcomes the challenge of linking far-apart quantum dots, paving the way for the development of larger, more complex quantum computers based on silicon quantum dots.
