31 Jul 2023: The United States currently lacks the talent required to maintain competitiveness in this field, posing a national security risk. The race to commercialize and deploy quantum systems has become a battleground of U.S.-China competition, with other countries like Australia, Japan, Canada, and the UK also making progress. The United States faces a shortage of quantum talent and a general STEM skills gap. To fill these gaps, international collaboration, initiatives to retain foreign-born workers, and reskilling programs are necessary.

29 Jul 2023: Quantum computing specialist EeroQ has successfully developed a Quantum Processing Unit (QPU) chip named “Wonder Lake” using a CMOS manufacturing approach. The chip is based on helium-electron qubits and has a qubit count of 2,432, making it one of the most densely populated QPU designs. EeroQ’s qubits have a high level of coherence and mobility, leading to greater efficiency and reduced overhead for error correction mechanisms. The company aims to achieve high-quality quantum gates and scalability, positioning itself as a leader in the commercial quantum computing future.

24 Jul 2023: Researchers have made significant progress in improving the accuracy of a technology used to control quantum bits (qubits), which is essential for scaling up quantum computers. The technology uses flux quanta, units of magnetic flux, to control superconducting qubits. By physically separating the qubits from the control circuits, researchers achieved an accuracy above 99%. This development could provide a more scalable and practical pathway to quantum computation. Further refinements could potentially increase the accuracy even more.

17 Jul 2023: Researchers at North Carolina State University have discovered a new distinct form of silicon called Q-silicon which, among other interesting properties, is ferromagnetic at room temperature.

12 Jul 2023: A record-breaking number of quantum bits, or qubits, have been proven to be entangled inside a quantum computer. There have been previous attempts to achieve this with a relatively large number of qubits, but none have been able to verify the entanglement.

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.
