Utilizing a multilayered composite approach, we have designed and constructed new class of artificial materials for thermal conduction. We show that an engineered material can be utilized to control the diffusive heat flow in ways inconceivable with naturally occurring materials. By shielding, concentrating, inverting current, experimentally demonstrate unique potential utility guiding flux.
Understanding magnetic phases in quantum mechanical systems is one of the essential goals condensed matter physics, and advent prototype simulation hardware has provided new tools for experimentally probing such systems.

Abstract The promise of quantum computing lies in harnessing programmable devices for practical applications such as efficient simulation materials and condensed matter systems. One important task is the geometrically frustrated magnets which topological phenomena can emerge from competition between thermal fluctuations. Here we report on experimental observations equilibration simulations, measured up to 1440 qubits with microsecond resolution. By initializing system a state obstruction,...
Utilizing a non-resonant graded material consisting of an array artificially patterned superconducting and soft ferromagnetic elements, we construct dc magnetic cloak. When external field is applied, find that the interior cloak completely shielded while exterior remains unperturbed, as if cloaked region are just empty space.

Continuous-flow hydrogenations provide greatly improved reaction efficiency due to the efficient mass-transfer between heterogeneous catalysts and hydrogen gas. However, reported flow were limited only simple functional group transformations, development of sophisticated catalysis such as enantioselective reductive C–C bond formations remains challenging. Herein, we have developed continuous-flow cyclization 1,6-enynes using chiral supported on heteropoly acid/amine-functionalized SiO2...
Artificially engineered materials---metamaterials---typically alter only one heat or electromagnetic parameter at once. Researchers test a metamaterial that behaves simultaneously like thermal concentrator and an electrical invisibility cloak.
Quantum annealing (QA) is a heuristic algorithm for finding low-energy configurations of system, with applications in optimization, machine learning, and quantum simulation. Up to now, all implementations QA have been limited qubits coupled via single degree freedom. This gives rise stoquastic Hamiltonian that has no sign problem Monte Carlo (QMC) simulations. In this paper, we report implementation measurements two superconducting flux canonically conjugate degrees freedom (charge flux)...
This paper proposes an optimum design method for a two-dimensional microchannel heat sink under laminar flow assumption that simultaneously provides maximal exchange and minimal pressure drop, based on topology optimization incorporating Pareto front exploration. First, the formulation of governing equations coupled thermal-fluid problem level set-based are briefly discussed. Next, is formulated as bi-objective problem. An algorithm exploration then constructed, scheme adaptively determines...
Computer-aided engineering techniques are indispensable in modern developments. In particular, partial differential equations commonly used to simulate the dynamics of physical phenomena, but very large systems often intractable within a reasonable computation time, even when using supercomputers. To overcome inherent limit classical computing, we present variational quantum algorithm for solving Poisson equation that can be implemented noisy intermediate-scale devices. The proposed method...

Solving partial differential equations for extremely large-scale systems within a feasible computation time serves in accelerating engineering developments.

Actually, there are several oracle-based simulations with quantum speedup, but their detailed implementations accordingly computational complexities all unclear.

Mg(SPh)2 has been found to be a highly active catalyst in photocatalytic alkylation reactions of methylene compounds with nonactivated alkenes. The desired proceeded smoothly afford the corresponding alkylated products high yields low loadings (0.2‐0.3 mol%). This protocol is applicable continuous‐flow system. Notably, magnesium an earth‐abundant metal, and exhibits higher catalytic activity than previously reported LiSPh.
Quantum optimization methods use a continuous degree-of-freedom of quantum states to heuristically solve combinatorial problems, such as the MAX-CUT problem, which can be attributed various NP-hard problems. This paper shows that some existing unified into solver find binary solution is most likely measured from optimal state. Combining this finding with concept random access codes (QRACs) for encoding bits on fewer qubits, we propose an efficient recursive relaxation method called (RQRAO)...
