The effect of thermal photons on exceptional points in coupled resonators
Grzegorz Chimczak, Anna Kowalewska-Kudłaszyk, Ewelina Lange +2
We analyse two quantum systems with hidden parity-time (PT) symmetry: one is an optical device, whereas another is a superconducting microwave-frequency device. To investigate thei…

Unavoidability of nonclassicality loss in PT-symmetric systems
Jan Perina, Adam Miranowicz, Joanna K. Kalaga +1
We show that the loss of nonclassicality (including quantum entanglement) cannot be compensated by the (incoherent) amplification of PT-symmetric systems. We address this problem b…
