Reconfigurable Nonlinear Activation Using Low‐Loss Ge3Sb2Te15 for Photonic Neural Networks
Nanophotonics, Volume 15, Issue 14, 27 July 2026.Composition‐engineered, low‐loss Ge3Sb2Te15 is identified from high‐throughput GST spreads and integrated with silicon microring resonators. Multistate optical programming produces tunable resonance responses and diverse fixed‐wavelength optical nonlinear activation functions, connecting phase‐change material discovery with programmable nanophotonic ...

Exponentially Enhanced Single‐Photon Cross‐Kerr Nonlinearity in Quantum Optomechanics
Annalen Der Physik, 2022AbstractStrong cross‐Kerr nonlinearity at the single‐photon level is crucial for various quantum applications, but usually very difficult to achieve. In this work, an efficient method to generate and exponentially enhance the cross‐Kerr nonlinearity in quantum optomechanics of two optical cavities coupled to a common mechanical resonator is proposed ...

ENTANGLEMENT CONCENTRATION WITH CROSS-KERR NONLINEARITY
International Journal of Modern Physics B, 2014We propose a protocol for realizing two entanglement concentration scheme with cross-Kerr nonlinearity and double cross-phase modulation method. In our protocols, two remote parties do not require the accurate information of the less entangled state and the double cross-phase modulation is introduced to overcome the errors caused by the imperfect Kerr

Nearly deterministic controlled-NOT gate with weak cross-Kerr nonlinearities
Quantum Information and Computation, 2012On the basis of the probe coherent state and weak cross-Kerr nonlinearities, we present a scheme of a nearly deterministic Controlled-NOT gate. In this construction, feed-forward methods, quantum nondemolition detectors and several optical elements are applied. It is a potentially practical quantum gate with certain features.

Polarization-entanglement purification and concentration using cross-Kerr nonlinearity
Quantum Information and Computation, 2011We present an entanglement purification protocol and an entanglement concentration protocol in this paper, resorting to cross-Kerr nonlinearities and interference of two coherent beams. Our purification protocol can be used to purify photon pairs not only from an ideal entangled source but also from a parametric down-conversion source by the ...

Complete Quantum Teleportation with a Crossed-Kerr Nonlinearity
2006We show how perfect Bell-state discrimination and complete quantum teleportation of the polarization state of a photon can he implemented employing a cross-Kerr medium. We show that, using the recently demonstrated ultraslow light propagation in coherent atomic media, the proposal can be realized with presently available technology.
