Amplification and cross-Kerr nonlinearity in waveguide quantum electrodynamics [PDF]
Physical Review A, 2020 We explore amplification and cross-Kerr nonlinearity by a three-level emitter (3LE) embedded in a waveguide and driven by two light beams. The coherent amplification and cross-Kerr nonlinearity were demonstrated in recent experiments, respectively, with a V and a ladder-type 3LE coupled to an open superconducting transmission line carrying two ...

Entanglement Purification for Logic-Qubit of Photon System Based on Parity Check Measurement Gate
Entropy, 2023 It has been found that logic-qubit entanglement has great potential for applications in quantum communication and quantum networks in recent years. However, along with the effects of noise and decoherence, the fidelity of the communication transmission ...

Experimental demonstration of cavity-free optical isolators and optical circulators
Physical Review Research, 2020 Cavity-free optical nonreciprocity components, which have an inherent strong asymmetric interaction between the forward- and backward-propagation direction of the probe field, are key to produce such as optical isolators and circulators. According to the

Frontiers in Quantum Science and Technology, 2022 Hyperentangled state analysis is an important module in high-capacity quantum communication. We present a self-assisted deterministic hyperentangled-Bell-state analysis (HBSA) scheme for photon system entangled in three degrees of freedom (DOFs), where ...

Photonic two-qubit parity gate with tiny cross–Kerr nonlinearity [PDF]
Physical Review A, 2012 The cross-Kerr nonlinearity (XKNL) effect can induce efficient photon interactions in principle with which photonic multiqubit gates can be performed using far fewer physical resources than linear optical schemes. Unfortunately, it is extremely challenging to generate giant cross-Kerr nonlinearities.

Entanglement transfer via cross-Kerr nonlinearity
Acta Physica Sinica, 2008 We propose a scheme for realizing entanglement transfer based on the cross-Kerr nonlinear interaction between field-modes. By using this scheme the entanglement can be transferred from the field-states with discrete variables to the field-states with continuous variables.

Observation of a large, resonant, cross-Kerr nonlinearity in a cold Rydberg gas
Physical Review Research, 2019 We report the experimental observation of a cross-Kerr nonlinearity in a free-space medium based on resonantly excited, interacting Rydberg atoms and electromagnetically induced transparency.

Entanglement concentration for arbitrary four-particle linear cluster states
Scientific Reports, 2017 Cluster states, whose model are a remarkably rich structure in measurement-based quantum computation, hold high degree of entanglement, while entanglement is very fragile during the process of transmission because of the inevitable interaction with the ...
