An international research team has developed a groundbreaking technique to integrate superconductors with semiconductors by patterning platinum on germanium and heating it to form a superconducting alloy, demonstrating coherent quantum states that could enable hybrid quantum processors combining the scalability of semiconductor qubits with the long-range connectivity of superconducting circuits.
A QuTech research team demonstrated initialization, readout, and universal control of four qubits created from eight germanium quantum dots, achieving quantum information transfer with 75% Bell state fidelity and establishing a versatile platform for quantum computing advancement.

ISTA physicists have developed a breakthrough method to connect superconducting qubits using fiber optics instead of traditional electrical signals, significantly reducing cooling requirements and potentially enabling the scaling and networking of quantum computers by converting optical signals to microwave frequencies that qubits can process.
Physicists achieved a quantum computing breakthrough by successfully connecting separate quantum processors through photonic links, enabling quantum teleportation of logical gates between modules and demonstrating the first distributed quantum computer system, which could potentially scale up without the limitations of cramming millions of qubits into a single device.

Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.
In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
Quasiparticles — long-lived particle-like excitations — are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs — a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems.
When two microscopic systems are entangled, their properties are linked to each other irrespective of the physical distance between the two. Manipulating this uniquely quantum phenomenon is what allows for quantum cryptography, communication, and computation. While parallels have been drawn between quantum entanglement and the classical physics of heat, new research demonstrates the limits of this comparison. Entanglement is even richer than we have given it credit for.
The quantum nature of objects visible to the naked eye is currently a much-discussed research question.

Optical fibres are the backbone of our modern information networks. From long-range communication over the internet to high-speed information transfer within data centres and stock exchanges, optical fibre remains critical in our globalised world.
Heat and computers do not mix well. If computers overheat, they do not work well or may even crash. But what about the quantum computers of the future? These high-performance devices are even more sensitive to heat. This is because their basic computational units — quantum bits or “qubits” — are based on highly-sensitive units, some of them individual atoms, and heat can be a crucial interference factor.
Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with computer simulations, which showed that chaos plays a crucial role: Only where chaos prevails do the well-known rules of thermodynamics follow from quantum physics.
Scientists have shown how three vortices can be linked in a way that prevents them from being dismantled. The structure of the links resembles a pattern used by Vikings and other ancient cultures, although this study focused on vortices in a special form of matter known as a Bose-Einstein condensate. The findings have implications for quantum computing, particle physics and other fields.
In a laboratory experiment, researchers have succeeded in realizing an effective spacetime that can be manipulated. In their research on ultracold quantum gases, they were able to simulate an entire family of curved universes to investigate different cosmological scenarios and compare them with the predictions of a quantum field theoretical model.
