Demonstration of a parity-time symmetry breaking phase transition using superconducting and trapped-ion qutrits
Alena S. Kazmina, Ilia V. Zalivako, Alexander S. Borisenko +21
Scalable quantum computers hold the promise to solve hard computational problems, such as prime factorization, combinatorial optimization, simulation of many-body physics, and quan…

Kinemon: inductively shunted transmon artificial atom
Daria Kalacheva, Gleb Fedorov, Julia Zotova +4
We experimentally investigate inductively shunted transmon-type artificial atoms as an alternative to address the challenges of low anharmonicity and the need for strong charge dis…

Hybrid quantum learning with data re-uploading on a small-scale superconducting quantum simulator
Aleksei Tolstobrov, Gleb Fedorov, Shtefan Sanduleanu +11
Supervised quantum learning is an emergent multidisciplinary domain bridging between variational quantum algorithms and classical machine learning. Here, we study experimentally a…
