We propose a qubit efficient scheme to study ground state properties of quantum many-body systems on near-term noisy intermediate scale computers. One can obtain tensor network representation the using number qubits smaller than physical degrees freedom. By increasing number, one exponentially increase bond dimension variational ansatz computer. Moreover, we construct circuits blocks which respect U(1) and SU(2) symmetries system show that they significantly speed up training process...
Federated learning has gained prominence as an effective solution for addressing data silos, enabling collaboration among multiple parties without sharing their data. However, existing federated algorithms often neglect the challenge posed by multi-modal distribution. Moreover, previous pioneering work face limitations in encrypting exponential and logarithmic operations of objective function with independent variables, they rely on a third-party cooperator encryption. To address these...
The generation and verification of large-scale entanglement are essential to the development quantum technologies. In this paper, we present an efficient scheme generate genuine multipartite a large number qubits by using Heisenberg interaction. This method can be conveniently implemented in various physical platforms, including superconducting, trapped-ion, cold-atom systems. order characterize output state, generalize stabilizer formalism develop witness method. particular, design generic...
With the development of controllable quantum systems, fast and practical characterization for multi-qubit gates is essential building high-fidelity computing devices. The usual way to fulfill this requirement via randomized benchmarking asks complicated implementation numerous twirling gates. How efficiently reliably estimate fidelity a process remains an open problem. In work, we propose character-cycle protocol character-average only using local individual operation. Our protocols can...
