Gold nanohexapods represent a novel class of optically tunable nanostructures consisting an octahedral core and six arms grown on its vertices. By controlling the length arms, their localized surface plasmon resonance peaks could be tuned from visible to near-infrared region for deep penetration light into soft tissues.

Abstract Here we report a breakthrough in the fabrication of long lifetime transmon qubit. We use tantalum films as base superconductor. By using dry etching process, obtained qubits with best T 1 503 μs. As comparison, also fabricated other popular materials, including niobium and aluminum, under same design processes. After characterizing their coherence properties, found that prepared have performance. Since process is stable highly anisotropic, it much more suitable for fabricating...
A Berry curvature is an imaginary component of the quantum geometric tensor (QGT) and well studied in many branches modern physics; however, metric as a real QGT less explored. Here, by using tunable superconducting circuits, we experimentally demonstrate two methods to directly measure for characterizing geometry topology underlying states parameter space. The first method probe transition probability after sudden quench, second one detect excitation rate under weak periodic driving....

Maintaining or even improving gate performance with growing numbers of parallel controlled qubits is a vital requirement for fault-tolerant quantum computing. For superconducting processors, though isolated one- two-qubit gates have been demonstrated high-fidelity, implementing these in commonly shows worse performance. Generally, this degradation attributed to various crosstalks between qubits, such as crosstalk due residual inter-qubit coupling. An understanding the exact nature critical...

Both forward modes, which are robust various obstacles, backward show an obvious frequency shift for widths. Numerical simulations by means...
We propose a pseudospin-field-dependent waveguide (PFDW) by constructing sandwiched heterostructure consisting of three magneto-optical photonic crystals (MOPCs) with different geometric parameters. The upper expanded MOPC applied an external magnetic field has broken time-reversal symmetry (TRS) and analogous quantum spin Hall (QSH) effect, while the middle standard lower compressed ones are not magnetized trivial. Attributed to TRS-broken-QSH effect MOPC, topological large-area one-way...
A multilevel qubit, or ``qudit,'' in a superconducting transmon shows high fidelity with several rudimentary algorithms, demonstrating the potential of quantum computing architecture based on up to four levels rather than just two.
