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…

Benchmarking Dark Matter Search using a Parity-Check Protocol with Machine-Learning Optimized Pulses
Yu-Han Chang, Ilya Moskalenko, Marko Kuzmanović +7
We report on an improved microwave detection protocol for dark matter candidates such as the axion and the dark photon. We employ a superconducting transmon qubit dispersively coup…

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…
