Fractional Magnonic Frequency Combs
Qian-Nan Huang, Zhiping Xue, Xudong Wang +5
Magnonic frequency combs (MFCs) are spectacular phenomena in microwave-driven high-quality magnets. Like the equally spaced prongs in a comb, conventional \textit{integer} MFCs are…
Non-Hermitian sensing from the perspective of post-selected measurements
Neng Zeng, Tao Liu, Keyu Xia +2
By employing the Naimark dilation, we establish a fundamental connection between non-Hermitian quantum sensing and post-selected measurements. The sensitivity of non-Hermitian quan…
Stationary entanglement in strongly coupled qubits
K. Xia, M. Macovei, J. Evers
The dynamics of two superconducting flux qubits coupled to each other and to a common bath is discussed. We focus on the case in which the qubit-qubit coupling strength dominates o…
Collectivity-assisted ground state cooling of a nanomechanical resonator
K. Xia, J. Evers
We discuss cooling of a nanomechanical resonator to its mechanical ground state by coupling it to a collective system of two interacting flux qubits. We find that the collectivity…
Robust creation of entangled states of two coupled flux qubits via dynamic control of the transition frequencies
K. Xia, M. Macovei, J. Evers +1
Coherent control and the creation of entangled states are discussed in a system of two superconducting flux qubits interacting with each other through their mutual inductance and i…
