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. Rev. Appl. 10, 054061 (2018)] we experimentally demonstrate simply-designed flux-controlled tunable coupler with continuous tunability adjusting the frequency, which can completely turn off adjacent qubit coupling. Utilizing two via coupler, implement different type of controlled-phase (CZ) gate 'dynamically...
Schrödinger’s cat originates from the famous thought experiment querying counterintuitive quantum superposition of macroscopic objects. As a natural extension, several “cats” (quasi-classical objects) can be prepared into coherent states, which is known as multipartite states demonstrating entanglement among macroscopically distinct Here, we present highly scalable approach to deterministically create flying by reflecting coherent-state photons microwave cavity containing superconducting...

Cross-resonance (CR) gates have emerged as a promising scheme for fault-tolerant quantum computation with fixed-frequency qubits. We experimentally implement an entangling CR gate by using microwave-only control in tunable coupling superconducting circuit, where the coupler provides extra degrees of freedom to verify optimal conditions constructing gate. By developing three-qubit Hamiltonian tomography protocol, we systematically investigate dependency fidelities on spurious qubit...
Abstract Tantalum (Ta) films with a body-centered cubic (BCC) α-phase play crucial role in high-performance Ta-based superconducting quantum processors. The growth of pure α-Ta at low temperatures has been long-term goal. Existing experience Ta on silicon substrates led to the belief that can only be stabilized high temperatures. In this study, we systematically analyzed mechanism sapphire using first-principles calculations, revealing narrow energy window for RT. This finding indicates...
Metabolic-associated fatty liver disease (MAFLD) is a common chronic metabolic worldwide that seriously threatens human health. The Xiaoji-chenpi formula (XCF), derived from QingGanSan (QGS), has previously been proven to be clinically effective in MAFLD. However, its pharmacological activity and mechanism have not studied depth. In this study, we explored determined the optimal amounts of cholesterol fat additives (4% 20%, respectively) for modeling zebrafish MAFLD via orthogonal tests....
Abstract According to traditional Chinese medicine (TCM) constitutional theory, individuals with phlegm-dampness constitution (PDC) are at increased risk for metabolic disorders. Previous studies have indicated that PDC exhibit gene expression changes associated disorders, even normal indices. However, the biological mechanisms underlying these remain unclear. The gut microbiota has recently emerged as a promising avenue elucidating TCM principles. Here, we revealed distinct and serum...

Digital quantum simulation of electron-phonon systems requires truncating infinite phonon levels into $N$ basis states and then encoding them with qubit computational basis. Unary the more compact binary/Gray are two most representative schemes, which demand $\mathcal{O}(N)$ $\mathcal{O}(\log{N})$ qubits as well $\mathcal{O}(N\log{N})$ gates respectively. In this work, we propose a variational state algorithm that reduces scaling number to both $\mathcal{O}(1)$ for obeying area law...
