Quantum Entanglement Found in One-Dimensional Gases at High Temperatures

Recent advances in quantum materials research have extended the Středa formula to non-equilibrium, periodically driven systems, revealing a universal, quantized magnetic response rooted in topology. By applying Cesàro summation, researchers demonstrated that what appears as a trivial sum of zeros actually encodes robust bulk magnetization and edge phenomena unique to Floquet systems. This approach resolves longstanding theoretical challenges and suggests new experimental strategies, such as particle-density measurements, to detect these effects even in disordered materials. The findings offer a framework for classifying nonequilibrium phases and investigating energy exchange in driven quantum systems.

Recent theoretical work has modeled vacuum tunneling in a two-dimensional superfluid, offering a new perspective on quantum phenomena previously thought to be experimentally inaccessible. By substituting superfluid helium for a vacuum and using its flow as an analog to a strong electric field, researchers demonstrated the spontaneous creation of vortex/anti-vortex pairs. This approach not only provides insights into quantum tunneling and phase transitions in two-dimensional systems but also challenges previous assumptions about vortex mass, suggesting it varies significantly during motion. These findings may refine our understanding of both superfluids and fundamental quantum processes.

“Heavy” Electrons Hold the Key to a New Type of Quantum Computer A research team from The University of Osaka has uncovered that “heavy fermions”—electrons with a dramatically increased effective mass—exhibit quantum entanglement governed by Planckian time in the compound Cerium‑Rhodium‑Tin (CeRhSn). This quasi‑kagome Kondo lattice material demonstrates non‑Fermi liquid behavior nearly up to room temperature, and heavy electron lifetimes approach the fundamental Planckian limit. The findings, reported in npj Quantum Materials, highlight anisotropic dynamical Planckian scaling in the Drude response below 80 K in the Ce quasi‑kagome plane, signaling quantum criticality tied to strong conduction–f‑electron hybridization . This discovery opens exciting possibilities for manipulating entanglement in solid‑state materials and designing novel quantum computing architectures based on Planckian‑time–controlled heavy fermions.

Scientists of Kyoto University and Hiroshima University have succeeded in the initial experimental measuring entangled state of the quantum W state, a basic multi-photon entangled state. The concept of quantum entanglement in which the physics of every photon cannot be explained individually is a challenge to classical physics and the basis of technologies of the next generation in quantum technologies. Creating multi-photon entangled states is not the only problem, it is important to locate the state. Traditional quantum tomography is proportional to the exponent of the number of measurements as the number of photons rises, and poses a big data collecting issue. Entangled measurement provides a one-shot model, which had been done before on GHZ states, but not on W states: They were led by Shigeki Takeuchi, who concentrated on the cyclic shift symmetry of the W state and suggested a quantum circuit using photonic quantum circuit based on quantum Fourier transformation of W states of any number of photons. They constructed a three-photon high-stability optical quantum device, which did not require active control to last long. With the help of the insertion of photons with selected polarizations, they identified the various types of three-photon W states, and they measured the fidelity of measurement, which is the likelihood of the correct result to occur in case of the input of a pure W-state. The breakthrough makes quantum teleportation, transfer of multi-photon entangled states, and measurement-based quantum computing possible. The authors intend to extend their approach to more multi-photon systems and build on-chip photonic quantum circuits of entangled measurements. #QuEdX #QuantumLeap #QuantumTechnology #NQM #QuantumValey #Physics #ResearchBreakthrough #Innovation #ScienceAndTech

𝐅𝐫𝐚𝐜𝐭𝐢𝐨𝐧𝐚𝐥 𝐄𝐱𝐜𝐢𝐭𝐨𝐧𝐬: 𝐓𝐡𝐞 𝐐𝐮𝐚𝐧𝐭𝐮𝐦 𝐏𝐚𝐫𝐭𝐢𝐜𝐥𝐞𝐬 𝐓𝐡𝐚𝐭 𝐁𝐫𝐞𝐚𝐤 𝐭𝐡𝐞 𝐑𝐮𝐥𝐞𝐬🧬✨   In 2025, physicists at Brown University uncovered something extraordinary: A new class of quantum particles called fractional excitons—entities that carry no overall charge, yet behave in ways that defy classical logic. These particles emerge from the fractional quantum Hall effect, where electrons move in quantized steps under extreme magnetic fields. But here’s the twist: Fractional excitons are formed by pairing quasiparticles with fractional charges. They exist in two-dimensional graphene layers, separated by nanocrystals. They follow non-standard quantum statistics, hinting at entirely new phases of matter. This isn’t just a lab curiosity. It’s a new frontier in quantum science: Could lead to topologically protected quantum states—ideal for fault-tolerant quantum computing. May unlock new quantum phases that go beyond what we thought possible. Offers a fresh lens on how atoms interact in extreme conditions. 💡 The atom was once the smallest unit of matter. Now, we’re discovering subatomic behaviors that rewrite the rules of existence. This is the kind of science that doesn’t just push boundaries—it redraws them. #QuantumFrontiers #FractionalExcitons #AtomicRevolution #QuantumParticles #QuantumHallEffect #GraphenePhysics #QuantumComputing #ScientificBreakthrough #LinkedInScience #PhysicsInnovation #BeyondTheAtom
