The networked world is increasingly being shaken by digital sabotage, cyber attacks, malware and the like. Yet IT security is more important than ever these days. Networks based on quantum physics could significantly improve the security of relevant systems. So-called quantum repeaters form the basis for this. These devices have been the subject of intensive research for several years, but are not yet marketable. A new joint project, in which Paderborn University is involved, therefore aims to develop new concepts and demonstrate them on real test tracks outside the laboratory.

Miami University and Cleveland Clinic are partnering to advance education in quantum computing and elevate Ohio’s global position in this transformative field. Through an innovative partnership, Ohio’s first specialized degree programs and research experiences in quantum computing will be established. This initiative also will cultivate scientific and entrepreneurial talent to develop companies, elevate businesses, and advance organizations that leverage quantum computing.

Using supercold environments and a quantum computer, Purdue researchers examined the evolution of a network of Ising spins in the presence of a transverse field. Much like ripples on water, the wave moves across the surface, but the water molecules move up and down, perpendicular to the wave's direction. This type of computational discovery is challenging with conventional or even supercomputers. This discovery, led by Arnab Banerjee, an assistant professor at Purdue University's Department of Physics and Astronomy, has been published in Nature Communications.

The EQUSPACE consortium (Enabling New Quantum Frontiers with Spin Acoustics in Silicon) has received 3.2 million euros from the European Innovation Council's (EIC) Pathfinder Open funding program to advance the development of silicon-based quantum technologies. In addition to the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the project brings together four other partners from three EU countries and convenes experts from the fields of spin qubits, optomechanics and atomic silicon modifications to develop a novel silicon-based quantum platform.

A research team led by The Hong Kong University of Science and Technology (HKUST) has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant advance in quantum physics research.

It is often difficult to find out which equations determine a particular quantum system. Normally, one first has to make theoretical assumptions and then conduct experiments to check whether these assumptions prove correct. Strikingly, researchers at the University of Innsbruck, opens an external URL in a new window, the Institute of Quantum Optics and Quantum Information, opens an external URL in a new window (IQOQI) and TU Wien (Vienna) have now jointly achieved an important step in this field: they have developed a method that allows them to read directly from the experiment which physical theory effectively describes the behaviour of the quantum system. This now allows for a new kind of quality control: it is possible to directly check whether the quantum simulator actually does what it is supposed to simulate. This should enable quantitative statements to be made about quantum systems that cannot be investigated directly.

Now, a team of researchers from IESL FORTH, Dr. Theocharis Lamprou and Dr. Paraskevas Tzallas, and ICFO, Dr. Javier Rivera-Dean, Philipp Stammer and ICREA Prof. Maciej Lewenstein, has successfully addressed both issues. They created generalized coherent state superpositions (GCSS), verified their quantum nature and employed them to drive a nonlinear optical process (which, per se, is indicative of the high photon number and intensity of the states). Their findings, demonstrated both theoretically and experimentally, have been reported in Physical Review Letters.

IonQ, a leader in the quantum computing and networking industry, today announced the completion of its acquisition of substantially all of the assets of Qubitekk, Inc., a prominent quantum networking company. The acquisition brings Qubitekk’s esteemed team, advanced technology, and extensive patent portfolio into IonQ’s operations, solidifying IonQ’s position at the forefront of quantum networking and computing.

Qolab, Inc. a leader in superconducting quantum computing, announced today that it secured over $16.0 million to date in its Series A financing round, led by Octave Ventures with co-investment from the Development Bank of Japan Inc. (DBJ), Wisconsin Alumni Research Foundation (WARF), and Phoenix Venture Partners. This investment represents a significant step in Qolab’s mission to develop utility-scale quantum computing technology by advancing scalability in quantum systems.

MicroCloud Hologram Inc., (the "Company"), based on their in-depth research and continuous innovation in quantum technology, they have pioneered an advanced technological solution: using a fast adiabatic driving protocol to achieve coherent control of two heavy hole spin qubits in a double quantum dot (QD) system. In traditional quantum experimental protocols, conventional methods such as linear ramps, π-pulses, or Landau-Zener channels have contributed to the incremental development of quantum control techniques. However, due to their inherent physical limitations, these methods struggle to meet the current stringent demands for high fidelity in quantum information processing. In contrast, the fast adiabatic driving protocol developed by HOLO demonstrates significant technological advantages.
