Coherent Amplifier-Empowered Quantum Interferometer: Preserving Sensitivity and Quantum Advantage under High Loss
Jie Zhao, Zeliang Wu, Haoran Liu +6
Quantum interferometers offer phase measurement capabilities that surpass the standard quantum limit (SQL), with phase sensitivity and quantum enhancement factor serving as key per…
Deterministic and Universal Frequency-Bin Gate for High-Dimensional Quantum Technologies
Xin Chen
High-dimensional photonic systems access large Hilbert spaces for quantum information processing. They offer proven advantages in quantum computation, communication, and sensing. H…
Mode Selection in Quantum Nonlinear Optics Using Optical Resonators
Xin Chen
Nonlinear optics underpins quantum photonics by enabling the generation and control of quantum states of light. We present new applications of optical resonators as mode selectors…
Quantum illumination via frequency-mode-based correlation-to-displacement conversion
Xin Chen, Zhibin Ye
Quantum illumination leverages entanglement to surpass classical target detection, even in high-noise environments. Remarkably, its quantum advantage persists despite entanglement…
