Phase-sensitive cascade quantum amplifier with nearly noiseless operation
Ilari Lilja, Ekaterina Mukhanova, Michael Perelshtein +5
Phase-sensitive parametric devices enable quadrature-selective amplification with the potential for sub-quantum-limited noise performance. In this work, we investigate the operatio…
Bipartite entanglement under frequency comb pumping in parametric Josephson circuits
Mikael Vartiainen, Ilari Lilja, Ekaterina Mukhanova +3
The creation of high-quality cluster states in superconducting microwave circuits is a relevant ingredient in continuous-variable quantum computing. Although large-scale cluster st…
Broadband lumped-element Josephson parametric amplifier with single-step lithography
T. Elo, T. S. Abhilash, M. R. Perelshtein +3
We present a lumped-element Josephson parametric amplifier (JPA) utilizing a straightforward fabrication process involving a single electron beam lithography step followed by doubl…
