Deterministic Local Expansion of W States
Can Yesilyurt, Sinan Bugu, Fatih Ozaydin +4
In large quantum systems multipartite entanglement can be found in many inequivalent classes under local operations and classical communication. Preparing states of arbitrary size…
Metrology with -symmetric cavities: Enhanced sensitivity near the -phase transition
Zhong-Peng Liu, Jing Zhang, Şahin Kaya Özdemir +7
We propose and analyze a new approach based on parity-time () symmetric microcavities with balanced gain and loss to enhance the performance of cavity-assisted metrol…
Distillation of photon entanglement using a plasmonic metamaterial
Motoki Asano, Muriel Bechu, Mark Tame +7
Plasmonics is a rapidly emerging platform for quantum state engineering with the potential for building ultra-compact and hybrid optoelectronic devices. Recent experiments have sho…
Optomechanically-Induced Transparency in partiy-time-symmetric microresonators
H. Jing, S. K. Özdemir, Z. Geng +5
Optomechanically-induced transparency (OMIT) and the associated slowing of light provide the basis for storing photons in nanoscale devices. Here we study OMIT in parity-time (PT)-…
Nonlinear quantum input-output analysis using Volterra series
Jing Zhang, Yu-xi Liu, Re-Bing Wu +5
Quantum input-output theory plays a very important role for analyzing the dynamics of quantum systems, especially large-scale quantum networks. As an extension of the input-output…
Phonon amplification in two coupled cavities containing one mechanical resonator
Hui Wang, Zhixin Wang, Jing Zhang +3
We study a general theory of phonon lasing [I. S. Grudinin et al., Phys. Rev. Lett. 104, 083901 (2010)] in coupled optomechancial systems. We derive the dynamical equation of the p…
