Quantum Applications… Simulating the universe

📃Scientific paper: Quantum Radio Astronomy: Data Encodings and Quantum Image Processing Abstract: We explore applications of quantum computing for radio interferometry and astronomy using recent developments in quantum image processing. We evaluate the suitability of different quantum image representations using a toy quantum computing image reconstruction pipeline, and compare its performance to the classical computing counterpart. For identifying and locating bright radio sources, quantum computing can offer an exponential speedup over classical algorithms, even when accounting for data encoding cost and repeated circuit evaluations. We also propose a novel variational quantum computing algorithm for self-calibration of interferometer visibilities, and discuss future developments and research that would be necessary to make quantum computing for radio astronomy a reality. ;Comment: 11 pages, 8 figures Continued on ES/IODE ➡️ https://etcse.fr/KaAdQ ------- If you find this interesting, feel free to follow, comment and share.

🚀 Unlocking the Mysteries of the Universe: Quantum Error-Correction in Quantum Field Theory and Gravity 🚀 Spacetime emerges from the Big Bang but how or what happens near a black hole singularity? These profound questions lie at the heart of our understanding of the universe. 🌌✨ 🔍 Keiichiro Furuya from UC Berkeley delves deep into the intersection of quantum error-correction (QEC), quantum field theory (QFT), and gravity to unravel the complexities of our cosmos. His work addresses pivotal questions such as: The classical spacetime can arise from the extreme conditions of the Big Bang and black hole singularities where quantum fluctuations dominate? Quantum Error-Correction in Holography: By applying QEC frameworks to holography, how information in the bulk theory is encoded on the boundary, enhancing our understanding of quantum gravity. 💡 Key Insights: Infinite-Dimensional Systems: Furuya provides the necessary mathematical tools using von Neumann algebras to study QEC in the infinite-dimensional realms of QFT and gravity. Approximate QEC and Renormalization Group (RG) Theory: The real-space RG theory can be viewed as an approximate error-correction code, offering new perspectives on the natural emergence of QEC in holography. Scalability: From the Planck length to cosmological scales, Furuya’s research bridges the gap between microscopic quantum phenomena and macroscopic gravitational effects. 🔬 Why It Matters: Understanding QEC in the context of QFT and gravity not only advances theoretical physics but also paves the way for future innovations in quantum computing and information theory. By decoding the universe's most enigmatic processes, we move closer to a unified theory that seamlessly integrates quantum mechanics with general relativity. Dive Deeper: Explore how it is shaping the future of quantum research and unraveling the fabric of spacetime itself.

#Quantum entanglement observed at Large Hadron Collider in historic breakthrough. In a groundbreaking discovery, scientists have observed quantum entanglement at the Large Hadron Collider (LHC) for the first time, marking a significant leap in the field of quantum physics. This remarkable phenomenon, where two particles become so interconnected that the state of one affects the other, regardless of distance, has been pivotal in advancing quantum information science. Now, quantum entanglement has reached new heights as researchers observed this effect in top quarks, some of the heaviest particles known to physics, at the highest energies ever recorded. https://lnkd.in/eRZhpgHp #quantum #quantumnetworks #quantumcomputing #quantumphysics #iyq #quantumscience #quantumtech #quantumcommunications

Groundbreaking Discovery: Photons Can Spend a Negative Amount of Time in an Atom Cloud! In a recent study out of the University of Toronto, a team of physicists led by Daniela Angulo, Kyle Thompson, Vida Michelle Nixon, Andy Jiao, Howard M. Wiseman, and Aephraim M. Steinberg uncovered a phenomenon that could redefine our understanding of light-matter interactions: a photon can spend a “negative amount of time” within a cloud of cold atoms as it passes through. Key Highlights of the Study: • Photon Group Delay in Cold Atoms: Typically, light slows down when passing through a material—a delay known as group delay. But in this study, the team demonstrated that photons could experience a negative group delay in certain conditions, suggesting that they effectively “exit” before they “enter.” • Experimental Verification: Using cold rubidium (Rb) atoms and leveraging the cross-Kerr effect (a nonlinear optical interaction), the researchers measured photon excitation times. Intriguingly, they found mean atomic excitation times that varied based on the signal pulse’s bandwidth—from negative values with narrowband pulses (-0.82τ0) to positive values with broader pulses (0.54τ0). • Real-World Implications for Quantum Physics: This counterintuitive behavior of photons could be transformative in fields like quantum optics and quantum computing, where controlling and understanding light-matter interactions at a quantum level is crucial. Why Does This Matter? The results challenge long-standing ideas about photon behavior in dispersive media, showing that negative group delays are not merely theoretical but have physical significance. This work adds a profound layer of complexity to our grasp of quantum systems and could pave the way for innovative technologies relying on quantum light manipulation. About the Research Team The collaboration brought together experts in quantum physics and optical science, demonstrating the power of interdisciplinary research. Their work not only showcases the University of Toronto’s leadership in quantum science but also opens doors for further exploration into the nature of time delays in quantum mechanics. As quantum science pushes forward, discoveries like these highlight the fascinating, often non-intuitive world of photons and atomic interactions, reshaping what we think is possible in physics. #QuantumPhysics #PhotonResearch #UniversityofToronto #AtomicExcitation #QuantumOptics #Photonics #NegativeTimeDelay #QuantumScience #OpticalPhysics #PhotonBehavior #CuttingEdgeResearch #QuantumMechanics #PhysicsInnovation #NonlinearOptics #QuantumTechnology #ScientificDiscovery
