https://lnkd.in/gGpqT8V4 - Chicago business media says the Illinois government is pressing hard to build a $20 billion, 150-acre quantum computing campus in Chicago. - The campus would be anchored by PsiQuantum. - The $20 billion figure refers to the potential for future business and government investments, as well as job creation. ‘Illinois may be on the verge of securing the largest technology project in its history—what is being labeled a “$20 billion, 150-acre quantum computing campus,” potentially anchored by Silicon Valley startup PsiQuantum, according to Crain’s Chicago Business. PsiQuantum, hot off an announcement that its receiving $600 million to build a manufacturing site in Australia, is reportedly considering two Chicago-area locations for the project, the business journal reports. ‘The proposed sites, the former U.S. Steel plant on the South Side and the former Texaco refinery in Lockport, are both under final review, with a decision expected soon. This initiative is part of a broader vision by Governor J.B. Pritzker’s administration, which pundits are referring to a modern-day Manhattan Project, to position Illinois as a leader quantum computing. ‘The initiative would initially create about 1,000 construction jobs and up to 500 direct jobs, including positions for hardware and software engineers. The project is designed to be accessible, with many positions requiring only associate’s degrees & specialized training. Additionally, the site would feature a cryogenic facility, essential for stabilizing subatomic particles used in quantum computing, which could cost between $300 million to $500 million. 'The selection of the former industrial sites is strategic, providing the necessary infrastructure for industrial-scale helium production, and the substantial water & power needed for the cryogenic process. The campus plans also include an R&D center to support the development of quantum [technology]. ‘The state’s investment in quantum technology is already considerable. Governor Pritzker’s administration previously allocated $200 million from Illinois’s capital budget to quantum initiatives, aiding in securing an additional $275 million in federal funding for local research projects. With another $500 million requested from the state legislature for further investment, Illinois is trying to make a push to become a federally recognized quantum hub, a designation that could bring up to $70 million in additional funding. 'The bet on quantum is not guaranteed. The Colorado quantum ecosystem is also making a play for that federal designation. Quantum computing, itself, is making profound progress toward practical uses, but it is uncertain as to exactly when that quantum practicality is achieved... There is also stiff competition within the quantum computing field with several quantum approaches being explored and exploited..'

5/7/2024 The quantum theory of gravitation, effective field theories and strings: Past and present by Clare Sansom , SciencePOD Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical theory. This description sets gravity apart from the other three forces—strong, weak, and electromagnetism—all described by quantum fields. Therefore, any attempt to unify the four forces must depend on a description of gravity that uses the principles of quantum mechanics. This has been an active area of theoretical physics since the 1930s. A historian and a physicist, Alessio Rocci from VUB in Brussels and Thomas Van Riet from KU Leuven in Belgium have set out a historical overview of the development of quantum theories of gravity to explain our current view on a future unified theory of the four forces. This work has been published in The European Physical Journal H.

n the 127 years since the electron was discovered, it has undergone more scrutiny than perhaps any other particle. As a result, its properties are not just well known, but rote, textbook material: Electrons have a smidgen of mass and negative electric charge. In a conductor, they swim relatively unimpeded as a current; in an insulator, they barely move. Over time, caveats have cropped up. Under an intense magnetic field, for example, electrons can lose their individual identities and form “quasiparticles”: collective entities, like the shape formed by a school of fish. But even these collective states have been well cataloged. So it came as a shock last year when a new effect was seen in electrons. Researchers at the University of Washington reported in August 2023 that in a stack of two atomically thin crystalline sheets offset from each other at a slight angle, electrons behaved like quasiparticles with fractional amounts of charge, such as −⅔ and −⅗. A few months later, a team at the Massachusetts Institute of Technology reported the same effect in another material. It was the first time that electrons had formed fractional quasiparticles without the enabling influence of a magnetic field. While predictions about the possibility of this particular effect date back to 2011, theorists are still puzzling over the new discovery. The new discovery isn’t incidental, or specific to a material. Rather, it’s universal and fundamental — the result of the quantum nature of the electron, albeit a behavior that has until now stayed hidden. While condensed matter physicists want to understand the breadth of electron behaviors for their own sake, there’s always the chance of uncovering the basis of a world-changing technology. In this case, the newfound effect may carry the seeds of long-sought quasiparticles with stable memories that could underpin a new and powerful approach to quantum computing. Outlandish Fractions The story that led to last year’s discoveries began back in 1879, when Edwin Hall, a graduate student at Johns Hopkins University, applied a magnetic field vertically through a flat metal ribbon with a current flowing along it. The field pushed the current of electrons to one edge of the ribbon. The resulting sideways current and the associated sideways resistance were later named after Hall. A century later, the German physicist Klaus von Klitzing investigated the Hall effect in a sheet of ultracold, pure gallium arsenide. As he cranked up the magnetic field, von Klitzing expected to see the Hall resistance increase steadily. But instead of growing continuously, the Hall resistance would lie flat and then jump up, forming a staircase of discrete steps. Even odder, the plateaus were found at integer multiples of the square of a fundamental constant: e, the charge of the electron. https://lnkd.in/dkkqnwFz

🚀 Exciting Breakthrough in Quantum Computing! 🚀 Infleqtion shares their latest research where they unveil a new implementation of bivariate bicycle codes (kind of Error Correction Code technics) using long-range Rydberg gates between stationary neutral atom qubits. 🔬 What they achieved: Optimized Design: By strategically arranging data and ancilla qubits, they've significantly reduced the communication distance required for executing complex quantum operations. High Fidelity Operations: Their Rydberg gate pulse design achieves an entanglement fidelity greater than 99.9% over distances exceeding 12 µm. Faster Quantum Error Correction: The result? A quantum error correction (QEC) cycle time of approximately 1.2 milliseconds for a [[144, 12, 12]] code—10x faster than previous methods. 🔗 Why It Matters: This implementation marks a substantial result, potentially reducing the cycle time for quantum error correction—an essential component for reliable #quantum computers. The success of these codes hinges on advancements in photonic beam switching and optical devices, paving the way for even more rapid quantum computations. 🛠️In the cold atom qubit modality, other research groups/companies are also using transport atoms that could be very slow, and Infleqtion's approach looks promising. 🌐 Stay tuned as we continue to push the boundaries of quantum computing technology, aiming for faster, more efficient quantum systems.

💥 Quantum theorists at UBC Blusson Quantum Matter Institute (Blusson QMI) have proposed a new approach to studying stacking ferroelectricity—spontaneous electric polarization—in layered, two-dimensional lab-grown materials. Ferroelectric materials are unique in their ability to “remember” their new state after the electric field is removed, which makes them useful in applications including solar cell technology and compact memory devices. “We've been learning in recent years that quantum geometry underlies a surprising range of the observable properties of materials,” said Dr. Marcel Franz, deputy scientific director at UBC Blusson QMI and a professor with the Department of Physics & Astronomy. “This work adds an important new entry to the growing list of phenomena that can be elucidated using this fascinating geometric approach.” “The most exciting part of our discovery is that the underlying physics behind stacking ferroelectricity can, in fact, be understood as a geometric property,” said UBC Blusson QMI postdoctoral fellow Dr. Benjamin T. Zhou, lead author of the study published in the journal Physical Review Letters. 👉 Read more: https://lnkd.in/gRSRXf36 #quantum #research #science #innovation #materials #discovery #QuantumBC #QuantumCoast #QuantumCanada

In a development at the intersection of quantum mechanics and general relativity, researchers have made significant strides toward unraveling the mysteries of quantum gravity. This work sheds new light on future experiments that hold promise for resolving one of the most fundamental enigmas in modern physics: the reconciliation of Einstein's theory of gravity with the principles of quantum mechanics. The longstanding challenge of unifying these two pillars of physics has tantalized scientists for decades, spawning various theoretical frameworks such as string theory and loop quantum gravity. However, without experimental verification, these theories remain speculative. How to test the quantum nature of gravity? Tangible means to probe the quantum behavior of the gravitational field were proposed within the last decade, based on the concept of "gravity-mediated entanglement."
