Mitigating the phase-mismatch effect in non-resonant four-wave mixing enabled by optimal control
Ning Jia, Hamid R. Hamedi, Jing Qian
Phase-mismatch in nonlinear optical processes can severely limit the propagation and conversion efficiency of light fields. Here, we present an efficient optimal-control strategy t…

Efficient and tunable frequency conversion using periodically poled thin-film lithium tantalate nanowaveguides
Simin Yu, Mingyue Qi, Huizong Zhu +4
Thin-film lithium tantalate (TFLT) has recently emerged as a promising photonic platform for chip-scale nonlinear optics due to its weaker photorefraction, higher optical damage th…

Quantum-preserved transport of excitations in Rydberg-dressed atom arrays
Panpan Li, Jing Qian, Weiping Zhang
To transport high-quality quantum state between two distant qubits through one-dimensional spin chains, the perfect state transfer (PST) method serves as the first choice, due to i…
