Preparing two-mode magnonic Schrödinger cat states in a cavity-magnon-qubit system
Gen Li, Gang Liu, Rong-Can Yang +1
The cavity-magnon-qubit system has recently been demonstrated as a new platform for preparing macroscopic quantum states in magnonic systems. Here, we propose to prepare a two-mode…
Macroscopic entanglement between two magnon modes via two-tone driving of a superconducting qubit
Rong-Can Yang, Gang Liu, Gen Li +1
The cavity-mediated coupling between magnons in an yttrium-iron-garnet (YIG) sphere and a superconducting qubit has recently been demonstrated as a new platform for preparing macro…
Magnon squeezing near a quantum critical point in a cavity-magnon-qubit system
Gang Liu, Gen Li, Rong-Can Yang +2
Preparing magnon nonclassical states is a central topic in the study of quantum magnonics. Here we propose to generate magnon squeezed states in a hybrid cavity-magnon-qubit system…
Learning the expressibility of quantum circuit ansatz using transformer
Fei Zhang, Jie Li, Zhimin He +1
With the exponentially faster computation for certain problems, quantum computing has garnered significant attention in recent years. Variational quantum algorithms are crucial met…
