Quantum System Scaling and Advantage for Fundamental and Applied Science (tracking no. A1052)
Abstract
Abstract: Quantum system scaling & advantage for fundamental and applied science(Approved for Public Release) The ability to sense a,t the quantum level provides the basic foundation for the emerging quantum revolution. Quantum sensing both underlies the ultimate s,uccess of quantum information science and provides the technological foundation for the full scientific and technological potentials,. We are witnessing a historical period of technology innovation and fundamental discovery, creating a confluence of the development, of increasingly large-scaled quantum systems with precise control and programmable capabilities and the exploration of new physics,based on frontier,e will advance the frontiers of quantum coherence and manipulation, connect many-body quantum phenomena with new advances in measure,ment science, implement entanglement for sensing and verify its quantum advantage, and explore the fundamental connection between qu,antum and gravitational physics. We aim to create the absolute frontier for measurement science and foundational technology, and ena,ble major scientific discoveries and breakthrough applications. The central vision of the proposed research activities is to bui,ld powerful quantum platforms to discover, understand, and utilize many-body Hamiltonians that are metrologically powerful and lay t,he foundation for a new generation of optical atomic clocks that are interconnected for rigorous verification. The JILA Sr optical l,attice clocks are among the most precise and accurate measurement systems today. We use a large number of atoms that are simultaneou,sly prepared, controlled, and interrogated, thus providing an outstanding platform to study many-body dynamics, including spin entan,nd tune many-body interaction effects. We will develop, characterize, and compare three Sr optical lattice clocks to realize truly r,evolutionary capabilities for time keeping, bringing quantum advantages to a class of quantum sensors, and obtaining new scientific,insights to the fundamental connection between quantum coherence and gravity. JILA Sr-1 is a one-dimensional optical lattice c,lock, which has demonstrated record measurement precision of 7 x 10-21, and we plan to improve this performance by x10. JILA Sr-2 is, a three-dimensional optical lattice clock loaded with a deeply degenerate Sr Fermi gas. JILA Sr-3 is a newly constructed 1D lattice, system that incorporates cavity-QED measurement-based spin squeezing for clock operation. All three systems will be phase-coherentl,y interconnected, allowing joint explorations of novel phenomena arising from the interplay of spin-orbit coupling, tunable interact,ions, SU(N) dynamics in a Fermi gas, and entanglement. Connecting and correlating quantum systems represent an emerging technol,ogy for realizing a novel class of quantum sensors. Our laboratory is uniquely positioned in the world to develop and engage these t,front of the field, generate entanglement and perform rigorous verification of quantum advantage at the state-of-the-art level, and,connect gravitation and quantum physics. Wide-ranging impacts are expected, including search for new physics, sensing technology for, geodesy, and navigation and timing independent of GPS. With the goal of reaching clock precision at 1 x 10-21, a tantalizing prospe,ct is to connect quantum superposition at 10 ?m scales to gravity, revealing its effect on quantum evolution or entanglement. On the, education front, our focus is to grow a team of young students and postdoctoral researchers into leading thinkers and technology in,novators for QIS.
