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…
Passive microwave circulation on a superconducting chip
Arkady Fedorov, N. Pradeep Kumar, Dat Thanh Le +3
Building large-scale superconducting quantum circuits will require miniaturisation and integration of supporting devices including microwave circulators, which are currently bulky,…
Qubit-controlled directional edge states in waveguide QED
Prasanna Pakkiam, N. Pradeep Kumar, Mikhail Pletyukhov +1
We propose an in-situ tunable chiral quantum system, composed of a quantum emitter coupled to a waveguide based on the Rice-Mele model (where we alternate both the on-site potentia…
