About

Liang Jiang is a Professor of Molecular Engineering at the University of Chicago Pritzker School of Molecular Engineering. His research theoretically investigates quantum systems and explores various quantum applications, including quantum sensing, quantum transduction, quantum communication, and quantum computation. His focus is on using quantum control and error correction to protect quantum information from decoherence, aiming to realize robust quantum information processing. Jiang has worked on modular quantum computation, global-scale quantum networks, room-temperature nano-magnetometers, sub-wavelength imaging, micro-optical quantum transduction, and error-correction-assisted quantum sensing and simulation. He received his BS from Caltech in 2004 and his PhD from Harvard University in 2009. Following his doctoral studies, he worked as a Sherman Fairchild postdoctoral fellow at Caltech. In 2012, Jiang joined Yale University as an assistant professor and later as an associate professor of Applied Physics. He was awarded the Alfred P. Sloan Research Fellowship and the David and Lucile Packard Foundation Fellowship in 2013. In 2019, he moved to his current position at the University of Chicago. His group investigates quantum control and quantum error correction across various physical platforms, with potential applications in quantum sensing, transduction, communication, and computation.

• Development of Quantum Interconnects (QuICs) for Next-Generation Information Technologies

  PRX Quantum · 2021 · 82 citations

  Just as classical information technology rests on a foundation built of interconnected information-processing systems, quantum information technology (QIT) must do the same. A critical component of such systems is the interconnect, a device or process that allows transfer of information between disparate physical media, for example, semiconductor electronics, individual atoms, light pulses in optical fiber, or microwave fields. While interconnects have been well engineered for decades in the rea…

• Constant-Overhead Fault-Tolerant Bell-Pair Distillation Using High-Rate Codes

  Physical Review Letters · 2025-09-25 · 9 citations

  articleOpen accessSenior author

  We present a fault-tolerant Bell-pair distillation scheme achieving constant overhead through high-rate quantum low-density parity-check (qLDPC) codes. Our approach maintains a constant distillation rate equal to the code rate while requiring no additional overhead beyond the physical qubits of the code. Full circuit-level analysis demonstrates fault-tolerance for input Bell-pair infidelities below a threshold ∼10%, readily achievable with near-term capabilities. Unlike previous proposals, our s…

• Quantum learning advantage on a scalable photonic platform

  Science · 2025-09-25 · 5 citations

  article

  Recent advances in quantum technologies have demonstrated that quantum systems can outperform classical ones in specific tasks, a concept known as quantum advantage. Although previous efforts have focused on computational speedups, a definitive and provable quantum advantage that is unattainable by any classical system has remained elusive. In this work, we demonstrate a provable photonic quantum advantage by implementing a quantum-enhanced protocol for learning a high-dimensional physical proce…
