Exciton-Polariton hybrid skin-topological states
Ruiqi Bao, R. Banerjee, S. Mandal +4
The non Hermitian skin effect, where bulk states accumulate at system boundaries, challenges the conventional bulk boundary correspondence. Here we propose a scheme to realize hybr…
Spectroscopy on a single nonlinear mode recognizes quantum states
Wouter Verstraelen, Stanisław Świerczewski, Andrzej Opala +7
Characterising optical quantum states is essential for the development of quantum technologies. While traditional approaches to perform full quantum state tomography are often expe…
Trembling Motion of Exciton-Polaritons Close to the Rashba-Dresselhaus Regime
Wen Wen, Jie Liang, Huawen Xu +4
We report the experimental emulation of trembling quantum motion, or Zitterbewegung, of exciton polaritons in a perovskite microcavity at room temperature. By introducing liquid cr…
Quantum theory of polariton weak lasing and polarization bifurcations
Huawen Xu, Timothy C. H. Liew, Yuri G. Rubo
The quantum theory of polariton condensation in a trapped state reveals a second-order phase transition evidenced by spontaneous polarization parity breaking in sub-spaces of fixed…
Topological enhancement of exciton-polariton coherence with non-Hermitian morphing
Ruiqi Bao, Huawen Xu, Wouter Verstraelen +1
The non-Hermitian skin effect (NHSE) has been intensely investigated over the past few years and has unveiled new topological phases, which have no counterparts in Hermitian system…
Topological Single Photon Emission from Quantum Emitter Chains
Yubin Wang, Huawen Xu, Xinyi Deng +3
We develop a scheme of generating highly indistinguishable single photons from an active quantum Su-Schrieffer-Heeger chain made from a collection of noisy quantum emitters. Surpri…
Spin-polarized antichiral exciton-polariton edge states
Ruiqi Bao, S. Mandal, Huawen Xu +3
We consider theoretically a system of exciton-polariton micropillars arranged in a honeycomb lattice. The naturally present TE-TM splitting and an alternating Zeeman splitting, whe…
Non-reciprocal Exciton-Polariton Ring Lattices
Huawen Xu, Kevin Dini, Xingran Xu +3
Recent experiments have shown the transfer of orbital angular momentum (OAM) from a non-resonant laser onto an exciton-polariton condensate, despite earlier views that the phase in…
The Roles of Kerr nonlinearity in a Bosonic Quantum Neural Network
Huawen Xu, Tanjung Krisnanda, Ruiqi Bao +1
The emerging technology of quantum neural networks (QNNs) attracts great attention from both the fields of machine learning and quantum physics with the capability to gain quantum…
Superpolynomial Quantum Enhancement in Polaritonic Neuromorphic Computing
Huawen Xu, Tanjung Krisnanda, Wouter Verstraelen +2
Recent proof-of-principle experiments have demonstrated the implementation of neuromorphic computing using exciton-polaritons, making use of coherent classical states [D. Ballarini…
Interaction induced bi-skin effect in an exciton-polariton system
Xingran Xu, Huawen Xu, S. Mandal +3
The non-Hermitian skin effect can be realized through asymmetric hopping between forward and backward directions, where all the modes of the system are localized at one edge of a f…
