The Toffoli gate is a three-qubit controlled-controlled-NOT gate, which plays central role in quantum information processing and computing. Recently, hybrid systems gates have attracted much attention. We propose an efficient scheme to implement with two nitrogen-vacancy center ensembles (NV ensembles) as the control qubits single superconducting flux qubit target qubit. This realized by employing NV coupled qutrit. constructed controlled-controlled-phase (CCPHASE) sandwiched between...

The quantum battery (QB), which can potentially store or dispatch energy more efficiently with advantage, has attracted considerable attention lately in the field of thermodynamics. With its a QB could be charged than classical battery. In this paper, we theoretically and experimentally exploit frequency-modulated stimulated Raman adiabatic passage (fmod-STIRAP) technique to improve charging (discharging) efficiency cascaded three-level that is constituted by superconducting transmon qutrit....

We propose a simple method to realize hybrid controlled–controlled-Z (CCZ) gate with two photonic qubits simultaneously controlling superconducting (SC) target qubit, by employing microwave cavities coupled SC ququart (a four-level quantum system). In this proposal, each control qubit is which encoded arbitrary orthogonal eigenstates (with eigenvalues ±1, respectively) of the photon-number parity operator. Since encoding states can take various states, proposal be applied CCZ gate, for have...

We propose to implement a hybrid multi-qubit quantum phase gate based on setup comprising multiple microwave cavities coupled common superconducting transmon qutrit in the circuit electrodynamics. The function of this is that related total number non-vacuum state will be introduced when qubit an excited state. Furthermore, we application, voting machine, with gate. This scheme scalable and simple operate, requiring just single step necessitating only reading states one target qubit. While...
