Abstract

Abstract A protocol for generating Greenberger‐Horne‐Zeilinger states in a system of coupled qubits is proposed. The Hamiltonian model assumes ‐wise interactions between the qubits and the presence of a controllable time‐dependent field acting upon one spin only. The dynamical problem is exactly solved thanks to the symmetries of the Hamiltonian model. The possibility of generating GHZ states simulating our physical scenario under both adiabatic and non‐adiabatic conditions is within the reach of the experimentalists. This aspect is discussed in detail.

Greenberger-Horne-Zeilinger States and Few-Body Hamiltonians

Paolo Facchi A, Giuseppe Florio, Saverio Pascazio +1 more

The generation of Greenberger-Horne-Zeilinger (GHZ) states is a crucial problem in quantum information. We derive general conditions for obtaining GHZ states as eigenstates of a Hamiltonian. We find that a necessary condition for an n-qubit GHZ state to be a nondegenerate eigenstate of a Hamiltonian is the presence of m-qubit couplings with m≥[(n+1)/2]. Moreover, we introduce a Hamiltonian with a GHZ eigenstate and derive sufficient conditions for the removal of the degeneracy.

Dynamic generation of Greenberger-Horne-Zeilinger states with coupled charge qubits

José Nogueira de, P. A. Oliveira, Fabricio Macedo de Souza +1 more

In this paper, we present a proof of principle of the formation of pure maximally entangled states from the Greenberger-Horne-Zeilinger (GHZ) class, in the experimental context of charged quantum dots. Each qubit must be identified as a pair of quantum dots, sharing an excess electron, coupled by tunneling. The electron-electron interaction is accounted for and is responsible for the coupling between the qubits. The interplay between coherent tunneling events and many-body interaction gives rise to the formation of highly entangled states. We begin by treating the problem of encoding three qubits in a system with three pairs of quantum dots, and the numerical analysis of the exact quantum dynamics to find the conditions for the generation of the GHZ states. An effective two-level model sheds light on the role of a high-order tunneling process behind the dynamics. The action of the main decoherence process, the charge dephasing, is quantified in the process. We then evaluate the physical requirements for the dynamical generation of GHZ states in an $N$-qubit scenario, and its challenges.

GHZ state generation of three Josephson qubits in the presence of bosonic baths

S Spilla, Rosanna Migliore, M Scala +1 more

We analyze an entangling protocol to generate tripartite Greenberger-Horne-Zeilinger states in a system consisting of three superconducting qubits with pairwise coupling. The dynamics of the open quantum system is investigated by taking into account the interaction of each qubit with an independent bosonic bath with an ohmic spectral structure. To this end a microscopic master equation is constructed and exactly solved. We find that the protocol here discussed is stable against decoherence and dissipation due to the presence of the external baths.

Global control methods for Greenberger-Horne-Zeilinger-state generation on a one-dimensional Ising chain

Xiaoting Wang, Abolfazl Bayat, Sougato Bose +1 more

We discuss how to prepare an Ising chain in a GHZ state using a single global control field only. This model does not require the spins to be individually addressable and is applicable to quantum systems such as cold atoms in optical lattices, some liquid- or solid-state NMR experiments, and many nanoscale quantum structures. We show that GHZ states can always be reached asymptotically from certain easy-to-prepare initial states using adiabatic passage, and under certain conditions finite-time reachability can be ensured. To provide a reference useful for future experimental implementations, three different control strategies to achieve the objective---adiabatic passage, Lyapunov control, and optimal control---are compared, and their advantages and disadvantages discussed, in particular in the presence of realistic imperfections such as imperfect initial state preparation, system inhomogeneity, and dephasing.

Greenberger-Horne-Zeilinger generation protocol for N superconducting transmon qubits capacitively coupled to a quantum bus

Samuel Aldana, Ying-Dan Wang, Christoph Bruder

We propose a circuit quantum electrodynamics (QED) realization of a protocol to generate a Greenberger-Horne-Zeilinger (GHZ) state for $N$ superconducting transmon qubits homogeneously coupled to a superconducting transmission line resonator in the dispersive limit. We derive an effective Hamiltonian with pairwise qubit exchange interactions of the $XY$ type, $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{g}(XX+YY)$, that can be globally controlled. Starting from a separable initial state, these interactions allow us to generate a multi-qubit GHZ state within a time ${t}_{\mathrm{GHZ}}\ensuremath{\sim}{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{g}}^{\ensuremath{-}1}$. We discuss how to probe the nonlocal nature and the genuine $N$-partite entanglement of the generated state. Finally, we investigate the stability of the proposed scheme to inhomogeneities in the physical parameters.

Generation of Long‐Distance Greenberger–Horne–Zeilinger States in a Driven Hybrid Quantum System

Xin Zeng, M LI, Bo Tian +3 more

ABSTRACT We propose a theoretical protocol for generating long‐distance Greenberger‐Horne‐Zeilinger states in a driven hybrid quantum system. The system consists of a central magnon coupled to multiple nitrogen–vacancy center spins positioned at a distance from the surface of the yttrium‐iron‐garnet sphere. A significant enhancement in the effective magnon‐spin coupling strength is achieved by driving the magnon with Kerr term. We analyze the dependence of the squeezing parameter on the driving field and adiabatically eliminate the magnonic mode under large detuning conditions via the Schrieffer–Wolff transformation, thereby establishing an effective all‐to‐all one‐axis‐twisting type spin–spin interaction essential for Greenberger–Horne–Zeilinger generation. Numerical simulations show that multi‐qubit Greenberger–Horne–Zeilinger states can be achieved even in the presence of dissipation. Furthermore, we investigate the impact of both inhomogeneous frequency broadening and non‐uniform coupling strengths between the magnon and spins. A cavity protection mechanism is introduced to mitigate frequency inhomogeneous broadening, while the tolerance to coupling inhomogeneity is also quantitatively evaluated.
