Robust Quantum Learning through Hamiltonian Reservoir Computing
Youya Xu, Chengyong Yu, Sanjib Ghosh
Quantum learning provides a versatile paradigm for information processing by exploiting the intrinsic representational capacity of high-dimensional Hilbert spaces. Here, we investi…

Time Crystals in Coupled Exciton-Polariton Condensates
Xuan Ye, Hong-Jin Xiong, Alexey Kavokin +1
In this paper, we show that time crystals can emerge in coupled exciton-polariton condensates without periodic external driving, enabled instead by incoherent gain and dissipation…

Dynamical Superfluid and Bose-Insulator Phases in Quantized Polariton Lattices
Sanjib Ghosh
We demonstrate that Hilbert-space quantization in polariton lattices-manifested as multiple quantized energy levels in strongly confined sites-provides an unconventional route to r…
