Continuously tunable single-photon level nonlinearity with Rydberg state wave-function engineering
Biao Xu, Gen-Sheng Ye, Yue Chang +2
Extending optical nonlinearity into the extremely weak light regime is at the heart of quantum optics, since it enables the efficient generation of photonic entanglement and implem…

Diagnosing Quantum Many-body Chaos in Non-Hermitian Quantum Spin Chain via Krylov Complexity
Yijia Zhou, Wei Xia, Lin Li +1
We investigate the phase transitions from chaotic to nonchaotic dynamics in a quantum spin chain with a local non-Hermitian disorder, which can be realized with a Rydberg atom arra…
