World of QUANTUM

💎 How Startups Are Driving the Quantum Computing Engine ⚡️ Many experts agree: Start-ups in particular are making significant progress in the construction of super-powerful quantum computers and application-related software, as well as in the development of the corresponding supply chains. Although they pursue different approaches, one thing is always at the forefront: photonics plays a crucial role. Some of the most innovative of them are supported by the DLR Quantencomputing-Initiative (Quantum Computing Initiative of German Aerospace Center, DLR). Here is an insight into two approaches that are being considered: 🪤 Ion traps: Charged atoms in tiny cages are manipulated by lasers and radio waves. This turns the atoms into qubits (the building blocks of quantum computers). Ion traps are a little different from #photonics, but they require lasers to cool and read the qubits. ❄️ ⚛️ Neutral atoms: These startups use individual atoms as qubits. Nature makes these atoms identical, which leads to very stable systems. Here, too, high-precision #laser|s play a key role in cooling, trapping and manipulating these atoms, as well as in complex optics. There is still much to discover in the future of #QuantumComputing, thanks in part to such groundbreaking startups – and the power of photonics. 👉🏼 Stay tuned and subscribe to our FREE newsletter: https://lnkd.in/dcYAJJFP https://lnkd.in/dXXr_7wh

💎 Diamond Defect Breakthrough Boosts Quantum Sensors! 🚀 The bar is being raised for quantum sensors: A new method can be used to build more powerful sensors using quantum mechanics for ultra-precise measurements, for example in medicine and engineering. For example, quantum sensors promise brain images 🧠 with extreme detail or improved air traffic control. 🛬 🛫 ▓ To build these sensors, researchers use qubits - special defects in diamonds. The new technique allows to control more defects, for example by adding gears to a machine to achieve more power. A special diamond defect is used to find and control hidden "dark spins". 💠 By chaining these spins together, a more powerful sensor can be created, further unlocking diamond's potential for quantum sensing.

🎥 ⚛️ Quantum computing goes Hollywood - in the series "His Dark Materials", the film adaptation of Philip Pullman's trilogy, a quantum computer appeared in season 2! Or, at least, the way it is often portrayed at the moment, namely in the form of a chandelier. The model in the series was presumably a replica and not a real system, of course 😉 And of course the functionality didn't correspond exactly to reality, but the books also belong to the fantasy genre 📚 Have you seen it and what did you think? #QuantumComputing #HisDarkMaterials

New Quantum State Chiral Spin-Orbital Current Discovered––Sheds light on quantum materials and optoelectronic innovations 🌀⚛️ A research team has unveiled a groundbreaking phenomenon: the "spin-orbital chiral current.". 🌌🔬 What makes this discovery so significant? Unlike conventional magnetic materials, where properties stem from electron spin and crystal ordering, this new state of matter harnesses chiral cooperative electron movements on an atomic scale. Thanks to the synergy between theory and experimentation, the existence of this elusive quantum state was confirmed. 🚀🔍 What does this mean for the future? 💻🔋 It can fundamentally change quantum materials research, open the door to new types of electronics that use chiral currents as information carriers, and could be a step forward in the search for next-generation optoelectronic devices and quantum technologies. https://lnkd.in/dppVAEQf Università Ca' Foscari di Venezia Consiglio Nazionale delle Ricerche Uniwersytet Jagielloński w Krakowie Uniwersytet Jagielloński (Jagiellonian University) Polish Academy of Sciences Università degli Studi di Salerno CNR-SPIN Synchrotron SOLEIL Aarhus University Politecnico di Milano Università degli Studi di Milano Seoul National University Wojciech Brzezicki Maria Teresa Mercaldo Anita Guarino Chiara Bigi Jill Miwa Domenico De Fazio Alberto Crepaldi Pasquale Orgiani Sandeep Kumar Chaluvadi, Ph.D. Giancarlo Panaccione Anupam Jana Vincent Polewczyk Ivana Vobornik Fabio Miletto Granozio Carmine Ortix #QuantumScience #physics #QuantumPhysics #QuantumMaterials [Image: CNR-SPIN - Artistic view of the chiral currents.]

✴️ Logical Qubit from Photonics Offers Error-Free Computing 💯 Scientists have achieved a major step forward in quantum computing with the creation of a logical qubit from a single light pulse, embedding built-in error correction capabilities. This innovative approach utilizes laser-generated light pulses, harnessing quantum optical states to correct errors inherently within the system. The single light pulse acts as both a physical and logical qubit, capable of error correction without the need for extensive entanglement. While further optimization is underway to enhance error tolerance, this work marks a crucial step towards scalable fault-tolerant #QuantumComputing using photon-based systems. ℹ️ News by University of Mainz: https://lnkd.in/dmhVDbzq ℹ️ News by University of Tokyo: https://lnkd.in/dap4b-qu Universität Tokio RIKEN NICT Kobe University Univerzita Palackého v Olomouci Johannes Gutenberg-Universität Mainz Peter van Loock #QuantumTechnology #QuantumInformation #photonics [Image: Peter van Loock/ U Mainz - The creation of a photonic "Schrödinger cat state" – in other words the quantum superposition of states of the laser pulse amplitude that can be distinguished on a macroscopic scale (white or black cat) – can only be achieved using the most advanced quantum optical techniques and has already been demonstrated to be possible. In the present experiment that is subject of the research paper, it proved to be feasible to extend this to three states (white, gray, and black cats). This light state thus approaches a logical quantum state in which errors can be, in principle, universally corrected.]
