Experimental realization of qubit-state-controlled directional edge states in waveguide QED
Prasanna Pakkiam, N. Pradeep Kumar, Chun-Ching Chiu +3
We experimentally realise the theoretical proposal for in-situ tunable photonic edge states emerging from qubits coupled to a waveguide with a photonic bandgap. These edge states a…

Fano-enhanced low-loss on-chip superconducting microwave circulator
N. Pradeep Kumar, Dat Thanh Le, Prasanna Pakkiam +2
Ferrite-free circulators that are passive and readily integratable on a chip are highly sought-after in quantum technologies based on superconducting circuits. In our previous work…
