Simple realization of a hybrid controlled-controlled-Z gate with photonic control qubits encoded via eigenstates of the photon-number parity operator
Qi-Ping Su, Liang Bin, Yu Zhang +1
We propose a simple method to realize a hybrid controlled-controlled-Z (CCZ) gate with two photonic qubits simultaneously controlling a superconducting (SC) target qubit, by employ…
One-step implementation of a multi-target-qubit controlled-phase gate with photonic qubits encoded via eigenstates of the photon-number parity operator
Qi-Ping Su, Liang Bin, Yu Zhang +1
In recent years, quantum state engineering and quantum information processing using microwave fields and photons have received increasing attention. In addition, multiqubit gates p…
Extension of Noether's theorem in PT-symmetric systems and its experimental demonstration in an optical setup
Q. C. Wu, J. L. Zhao, Y. L. Fang +4
Noether's theorem is one of the fundamental laws in physics, relating the symmetry of a physical system to its constant of motion and conservation law. On the other hand, there exi…
Generating Bell states and -partite states of long-distance qubits in superconducting waveguide QED
Guo-Qiang Zhang, Wei Feng, Wei Xiong +3
We show how to generate Bell states and -partite states of long-distance superconducting (SC) qubits in a SC waveguide quantum electrodynamical (QED) system, where SC qubits…
-photon blockade with an -photon parametric drive
Yan-Hui Zhou, Fabrizio Minganti, Wei Qin +5
We propose a mechanism to engineer an -photon blockade in a nonlinear cavity with an -photon parametric drive . When an -photon-excitation reson…
