Welcome to the [Quantum Information and Theory Lab]
Our laboratory is dedicated to exploring the cutting-edge of Quantum Information Science, with a research focus spanning from the fundamental building blocks of quantum mechanics to the frontier applications of quantum computing hardware. We firmly believe that unraveling the unique correlations within the quantum world is key to advancing next-generation quantum technologies. By starting from pure theory and actively integrating with advanced quantum hardware platforms, our research team aims to bridge the gap between foundational quantum concepts and their practical applications.
Unveiling the Nature of Quantum Nonlocality and Quantum Steering
Quantum steering and nonlocality are the core research pillars of our laboratory. We are not only committed to the geometric quantification and witnesses of Einstein-Podolsky-Rosen (EPR) steering, but we also extend the concept of spatial nonlocality into the time domain. We investigate the hierarchical structure of temporal quantum correlations in multi-dimensional systems and superconducting qubits. Furthermore, our team actively develops and experimentally verifies Measurement-Device-Independent (MDI) and Semi-Device-Independent (SDI) quantum protocols, providing a robust theoretical and experimental foundation for future secure quantum communication and certification.
Constructing Comprehensive Quantum Resource Theories
We treat the elusive phenomena in quantum systems as quantifiable and operational "resources." Our laboratory deeply investigates the essence of measurement incompatibility and has demonstrated the fundamental limitations of stochastic steering distillation. We also extend our reach into dynamical and memory resource theories, exploring the potential of entanglement-breaking channels as quantum memory resources, and evaluating the applied value of global coherence in quantum discord. Through this, we aim to clarify the conversion efficiency and physical limits of various quantum resources during information processing.
Bridging Frontier Technologies with Quantum Hardware Experiments
Beyond deepening theoretical understanding, our laboratory places a strong emphasis on grounding our research outcomes in current quantum hardware platforms. We utilize cloud quantum computers and superconducting quantum circuits to perform deterministic logic gate operations, benchmark quantum state transfers, and experimentally verify non-macrorealistic states. Recently, our team has also explored mechanisms for accelerating the generation of multipartite entanglement in non-Hermitian and passive PT-symmetric superconducting systems.
Interdisciplinary Innovation and Applications
To tackle increasingly complex quantum information challenges, we actively incorporate interdisciplinary technologies and methodologies. For instance, our team utilizes Deep Learning to optimize steering measurement settings and leverages quantum steering to enhance noisy quantum metrology. Additionally, we venture into the field of quantum thermodynamics, investigating the operational mechanisms of Maxwell's demon engines under pure dephasing noise environments.
The [Quantum Information and Theory Lab] strives to continuously expand the boundaries of quantum information through the tight integration of theoretical deduction and experimental verification. We welcome researchers and students passionate about quantum science to join us in exploring the infinite possibilities of the quantum world.
