Vehicular Ad Hoc Networks (VANETs) are the backbone of Intelligent Transportation Systems, aiming to enhance road safety, traffic efficiency, and comfort in driving. One of the critical factors influencing VANET performance is the routing protocol implemented. The current study evaluates the impact of three different routing protocols, i.e., Ad-hoc On-demand Distance Vector (AODV), Destination-Sequenced Distance Vector (DSDV), and Dynamic MANET On-demand (DYMO) on VANET performance in urban scenarios. Through comprehensive simulations using a realistic city scenario, we assess each protocol's performance based on several critical metrics such as packet delivery ratio, end-to-end delay, and network overhead. Our findings indicate significant differences in the performance of these protocols under various urban network conditions (AODV), being the best among all.
We present a programmable analog simulator with up to 105 lattice sites capable of simulating 2D and 3D lattices, as well as lattices with non-planar connectivity. We also demonstrate the injection of arbitrary lattic...
In a recent work by us [Ge et al., Phys. Rev. A 110, L010402 (2024)], we have derived a series of polygon relations of bipartite entanglement measures that is useful to reveal entanglement properties of discrete, cont...

We experimentally demonstrate a virtual two-qubit gate and characterize it using quantum process tomography (QPT). The virtual two-qubit gate decomposes an actual two-qubit gate into single-qubit unitary gates and projection gates in quantum circuits for expectation-value estimation. We implement projection gates via midcircuit measurements. The deterministic sampling scheme reduces the number of experimental circuit evaluations required for decomposing a virtual two-qubit gate. We also apply quantum error mitigation to suppress the effect of measurement errors and improve the average gate fidelity of a virtual controlled-Z (CZ) gate to fav=0.9938±0.0002. Our results highlight a practical approach to implement virtual two-qubit gates with high fidelities, which are useful for simulating quantum circuits using fewer qubits and implementing two-qubit gates on a distant pair of qubits.
Let F (n, k) be a hypergeometric function that may be expressed so that n appears within initial arguments of inverted Pochhammer symbols, as in factors of the form 1/(n/k. Only in exceptional cases is F (n, k) such t...
