Fixed-frequency superconducting quantum processors are one of the most mature computing architectures with high-coherence qubits and simple controls. However, high-fidelity multi-qubit gates pose tight requirements on individual qubit frequencies in these , constraints difficult to satisfy when constructing larger due large dispersion fabrication Josephson junctions. In this article, we propose...

There has been an assumption that spectrum can be divided into segments and then auctioned off. It has been assumed that this is optimal in terms of its benefit to the public and that the FCC in so doing is optimizing the public good. There has been an alternative conjecture, termed the “Gilder” conjecture, that segmenting bandwidth is not the best means and that using all of the bandwidth amon...

a novel distributed frequency allocation scheme named as exponential distribution based frequency allocation (EDFA) is proposed in Fractional Frequency Reuse (FFR) aided OFDMA networks. EDFA has a flexible adjustment between fairness and throughput. Simulation results demonstrate that compared to the proportional fairness (PF) allocation and equal rate allocation (ERA) schemes, EDFA could achie...

Past research on the broadband digital divide indicates a widening divide in which developing countries are falling further behind countries in the developed world. In response to this problem, the World Bank has advocated a “mobile first” strategy for developing countries. Unfortunately, there is little understanding of what determines mobile broadband adoption or diffusion in developing count...

As the increased demands of wireless channel, there is the need for the proper utilization of the spectrum which leads us to the new technique called cognitive radio technologies. Static spectrum allocation need to merge with a technique where it can be share for the proper utilization of the spectrum. Higher capacity requirement is of great need. As long as the technology is been evolving the ...

The explosion of wireless applications has created an ever increasing demand for radio spectrum and this has put a lot of pressure on service providers to meet the end user’s requirement for higher bandwidth. In present scenario, the access to radio spectrum for most of the wireless applications/services is based on some well-coordinated but static spectrum allocation principle. However many st...
