Perfect state transfer in quantum photonic networks based on Fourier modes
Sunita Meena, Sugar Singh Meena, Paulo A Brandão +1
We propose a quantum network consisting of optical waveguides in the linear regime for quantum state transfer. The circular topology of our network introduces novel functionalities…

Latent symmetry in a minimal non-Hermitian trimer
Paulo A. Brandão
We study a minimal non-Hermitian trimer with latent symmetry formed by a cospectral pair of sites embedded in a three-site network with nonreciprocal couplings. We show that cospec…
