Non-adiabatic holonomic quantum computation in linear system-bath coupling
Chunfang Sun, Gangcheng Wang, Chunfeng Wu +4
Non-adiabatic holonomic quantum computation in decoherence-free subspaces protects quantum information from control imprecisions and decoherence. For the non-collective decoherence…
Hubbard model for atomic impurities bound by the vortex lattice of a rotating BEC
T. H. Johnson, Y. Yuan, W. Bao +3
We investigate cold bosonic impurity atoms trapped in a vortex lattice formed by condensed bosons of another species. We describe the dynamics of the impurities by a bosonic Hubbar…
The photon pair source that survived a rocket explosion
Zhongkan Tang, Rakhitha Chandrasekara, Yue Chuan Tan +3
We report on the performance of a compact photon pair source that was recovered intact from a failed space launch. The source had been embedded in a nanosatellite and was designed…
Optical Intensity Interferometry through Atmospheric Turbulence
Peng Kian Tan, Aik Hui Chan, Christian Kurtsiefer
Conventional ground-based astronomical observations suffer from image distortion due to atmospheric turbulence. This can be minimized by choosing suitable geographic locations or a…
Quantum walk as a simulator of nonlinear dynamics: Nonlinear Dirac equation and solitons
Chang-Woo Lee, Paweł Kurzyński, Hyunchul Nha
Quantum walk (QW) provides a versatile tool to study fundamental physics and also to make a variety of practical applications. We here start with the recent idea of {\it nonlinear}…
Heisenberg's error-disturbance relations: a joint measurement-based experimental test
Yuan-yuan Zhao, Paweł Kurzyński, Guo-yong Xiang +2
The Heisenberg's error-disturbance relation is a cornerstone of quantum physics. It was recently shown to be not universally valid and two different approaches to reformulate it we…
