Abstract: Spin chains have long been considered an effective medium for long-range interactions, entanglement generation, and quantum state transfer. In this work, we explore the properties of a spin chain implemented with superconducting flux circuits, designed to act as a connectivity medium between two superconducting qubits. The susceptibility of the chain is probed and shown to support long-range, cross chain correlations. In addition, interactions between the two end qubits, mediated by the coupler chain, are demonstrated. This work has direct applicability in near term quantum annealing processors as a means of generating long-range, coherent coupling between qubits.

The controlled exciton transport of the Multi-chain system by cavity-dressed energy level crossings and anticrossings [2.859884413610466]
We study the exciton transport of the two-dimensional system consisting of two-level multichains with various coupling configurations in a cavity. Two types of the chains are considered, including Tavis-Cummings and Su-Schrieffer-Heeger chain. It is discovered that the exciton transport effciency is closely related with the parity of both the length and the number of chains.

We examine spin excitation or polarization transfer via long-range interacting spin chains with diagonal and off-diagonal disorder. We identify the energy eigenstates of the system with large localization length and sufficient support at the chain boundaries. We quantify the performance of two transfer schemes involving weak static couplings of the sender and receiver spins to the chain.

Coupled superconducting spin qubits with spin-orbit interaction [0.0]
Superconducting spin qubits, also known as Andreev spin qubits, promise to combine the benefits of superconducting qubits and spin qubits defined in quantum dots. We show that superconducting spin qubits can be coupled to each other via the superconductor to implement two-qubit quantum gates. We propose a scalable network of superconducting spin qubits which is suitable for implementing the surface code.

Engineering long-range interactions in cold-atom quantum simulators can lead to exotic quantum many-body behavior. Here, we propose several tuning knobs, accessible in current experimental platforms, that allow to further control the range and shape of the mediated interactions.

Superconducting coupler with exponentially large on-off ratio [68.8204255655161]
Tunable two-qubit couplers offer an avenue to mitigate errors in multiqubit superconducting quantum processors. Most couplers operate in a narrow frequency band and target specific couplings, such as the spurious $ZZ$ interaction. We introduce a superconducting coupler that alleviates these limitations by suppressing all two-qubit interactions with an exponentially large on-off ratio.

We experimentally study a metamaterial made of eight superconducting transmon qubits with local frequency control. We observe the formation of super- and subradiant states, as well as the emergence of a polaritonic bandgap. The circuit of this work extends experiments with one and two qubits towards a full-blown quantum metamaterial.

Controlled quantum state transfer in $XX$ spin chains at the Quantum Speed Limit [62.997667081978825]
In homogeneous chains it implies that taking information from one extreme of the chain to the other will take a time $O(N/2)$, where $N$ is the chain length. We design control pulses that achieve near perfect population transfer between the extremes of the chain at times on the order of $N/2$, or larger.

Long-range interaction in an open boundary-driven Heisenberg spin lattice: A far-from-equilibrium transition to ballistic transport [62.997667081978825]
We study an open Heisenberg XXZ spin chain with long-range Ising-type interaction. We find that the chain lengths for this transition are increasing with decreasing range of the Ising-type interactions between distant spins. The transition can be explained by the suppression of ferromagnetic domains at the edges of the chain.

We investigate the transfer of genuine multipartite entanglement across a spin-1/2 chain with nearest-neighbor XX-type interaction. We find that high-quality multipartite entanglement transfer is achieved at the same time that three excitations are transferred to the opposite edge of the chain.
