What happens when trailblazing engineers and industry professionals team up? The answer may transform the future of computing efficiency for modern data centers.

Data centers house and use large computers to run massive amounts of data. Oftentimes, the processors can’t keep up with this workload because it’s taxing to predict and prepare instructions to carry out. This slows the flow of data. Thus, when you type a question into a , the answer generates more slowly or doesn’t provide the information you need.

To remedy this issue, researchers at Texas A&M University developed a new technique called Skia in collaboration with Intel, AheadComputing, and Princeton to help computer processors better predict future instructions and improve computing performance.

Researchers have achieved a crucial milestone in quantum computing. They have created an operating system capable of enabling communication between quantum computers using different technologies.

This system, named QNodeOS, represents a significant advancement for quantum machine interoperability. Unlike classical systems like Windows or iOS, it is designed to handle the unique complexity of qubits, regardless of their physical nature. This innovation paves the way for more flexible and powerful quantum networks.

Researchers at QuTech in Delft have combined superconductors and quantum dots to observe and manipulate so-called Majorana bound states, which have properties that could enable stable quantum computation. By building a chain of three coupled quantum dots in a two-dimensional electron gas, they were able to demonstrate properties of Majoranas that are essential for the study of Majorana-based quantum bits.

The results are published in Nature.

One of the key issues in quantum computing remains the inherent instability of quantum bits. In the quest for fault-tolerant quantum computers, topological quantum bits are expected to be significantly less prone to errors. Key to these qubits are quasiparticles called Majorana bound states, which have been predicted to appear on opposite edges of one-dimensional superconducting systems.

Innsbruck physicists have presented a new architecture for improved quantum control of microwave resonators. In a study recently published in PRX Quantum, they show how a superconducting fluxonium qubit can be selectively coupled and decoupled with a microwave resonator and without additional components. This makes potentially longer storage times possible.

Microwave resonators are considered a promising building block for the development of robust quantum computers, as they store quantum information in more complex states. This simplifies and allows significantly longer storage times.

“The storage time of of these microwave resonators has so far been limited by undesirable interactions with the used to control them,” explains Gerhard Kirchmair from the Department of Experimental Physics at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences.

Interdisciplinary teams across the Quantum Systems Accelerator (QSA) are using innovative approaches to push the boundaries of superconducting qubit technology, bridging the gap between today’s NISQ (Noisy Intermediate-Scale Quantum) systems and future fault-tolerant systems capable of impactful science applications.

QSA is one of the five United States Department of Energy National Quantum Information Science (QIS) Research Centers, bringing together leading pioneers in (QIS) and engineering across 15 partner institutions.

A superconducting is made from such as aluminum or niobium, which exhibit quantum effects when cooled to very low temperatures (typically around 20 millikelvins, or −273.13° C). Numerous technology companies and research teams across universities and national laboratories are leveraging for prototype scientific computing in this rapidly growing field.
