A review article named Polariton condensates for classical and quantum computing appeared recently in Nature Review Physics. Alexey Kavokin, Chair Professor of Physics, director of International Center of Polaritonics (ICP) of Westlake University, is the first and corresponding author.


In this Review, Kavokin and the co-authors present the development of polariton lasers in the past two decades and specifically address the recent progress in topological polaritonics, neuromorphic architectures, polariton simulators and quantum computers.


To begin with,Kavokin etc. reviewed the development of polariton lasers, from its earliest realization out of optical pumping to latest achievement in lasing with electronic injection. Then they went through interesting material people have proposed and tested for polaritonic engineering, including TMDCs, organics, perovskites and liquid crystals.


In the second part, the authors reviewed application of topological concepts to polaritonic platforms, e.g. lasing from a topological edge experimentally realized in a 1D lattice of micropillars, and polariton topological insulator realized with a polariton honeycomb lattice. They summarized that in theory nonlinearity in polaritons can be used to induce non-trivial topology, giving rise to chiral, antichiral or valley Hall edge states. In addition to nonlinearity, their non-Hermiticity also make polaritons highly suited for engineering topological features.


In the third and fourth part, the authors reviewed a variety of proposals for applications of polariton condensates in classical and quantum information processing, e.g. several recent proposals on polariton XY-simulators, neuromorphic computing with exciton-polaritons and qubits based on polariton condensates.


The authors have a very positive outlook on polariton condensates for classical and quantum computing, in the light of the availability to so many new structure and materials, plus the recent advances in topological polaritonic enabled efficient control of light-matter coupling that may help signal readout. They claimed that the polariton platform is likely to become a strong competitor to the superconductor platform.
