Microwave Circulation in an Extended Josephson Junction Ring
Dat Thanh Le, Arkady Fedorov, Thomas M. Stace
Circulators are nonreciprocal devices that enable directional signal routing. Nonreciprocity, which requires time-reversal symmetry breaking, can be produced in waveguides in which…

The superconducting grid-states qubit
Long B. Nguyen, Hyunseong Kim, Dat T. Le +9
Decoherence errors arising from noisy environments remain a central obstacle to progress in quantum computation and information processing. Quantum error correction (QEC) based on…

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…
