Determination of Molecular Energies via Quantum Imaginary Time Evolution in a Superconducting Qubit System
Zhiwen Zong, Sainan Huai, Tianqi Cai +10
As a valid tool for solving ground state problems, imaginary time evolution (ITE) is widely used in physical and chemical simulations. Different ITE-based algorithms in their quant…
Experimental preparation of generalized cat states for itinerant microwave photons
Zenghui Bao, Zhiling Wang, Yukai Wu +11
Generalized cat states represent arbitrary superpositions of coherent states, which are of great importance in various quantum information processing protocols. Here we demonstrate…
Verifying quantum information scrambling dynamics in a fully controllable superconducting quantum simulator
J. -H. Wang, T. -Q. Cai, X. -Y. Han +10
Quantum simulation elucidates properties of quantum many-body systems by mapping its Hamiltonian to a better-controlled system. Being less stringent than a universal quantum comput…
A flying Schrödinger cat in multipartite entangled states
Zhiling Wang, Zenghui Bao, Yukai Wu +11
Schrödinger's cat originates from the famous thought experiment querying the counterintuitive quantum superposition of macroscopic objects. As a natural extension, several "cats" (…
Perturbation impact of spectators on a cross-resonance gate in a tunable coupling superconducting circuit
T. -Q. Cai, X. -Y. Han, Y. -K. Wu +7
Cross-resonance (CR) gate has emerged as a promising scheme for fault-tolerant quantum computation with fixed-frequency qubits. We experimentally implement entangling CR gate by us…
Error analysis in suppression of unwanted qubit interactions for a parametric gate in a tunable superconducting circuit
X. Y. Han, T. Q. Cai, X. G. Li +7
We experimentally demonstrate a parametric iSWAP gate in a superconducting circuit based on a tunable coupler for achieving a continuous tunability to eliminate unwanted qubit inte…
Tunable coupler for realizing a controlled-phase gate with dynamically decoupled regime in a superconducting circuit
X. Li, T. Cai, H. Yan +13
Controllable interaction between superconducting qubits is desirable for large-scale quantum computation and simulation. Here, based on a theoretical proposal by Yan et al. [Phys.…
