Sparse seismic imaging using variable projection
Aleksandr Y. Aravkin, Tristan van Leeuwen, Ning Tu
We consider an important class of signal processing problems where the signal of interest is known to be sparse, and can be recovered from data given auxiliary information about ho…
Process verification of two-qubit quantum gates by randomized benchmarking
A. D. Córcoles, Jay M. Gambetta, Jerry M. Chow +5
We implement a complete randomized benchmarking protocol on a system of two superconducting qubits. The protocol consists of randomizing over gates in the Clifford group, which exp…
Effects of optical and surface polar phonons on the optical conductivity of doped graphene
Benedikt Scharf, Vasili Perebeinos, Jaroslav Fabian +1
Using the Kubo linear response formalism, we study the effects of intrinsic graphene optical and surface polar phonons (SPPs) on the optical conductivity of doped graphene. We find…
Mid-infrared plasmons in scaled graphene nanostructures
Hugen Yan, Tony Low, Wenjuan Zhu +6
Plasmonics takes advantage of the collective response of electrons to electromagnetic waves, enabling dramatic scaling of optical devices beyond the diffraction limit. Here, we dem…
Building User-defined Runtime Adaptation Routines for Stream Processing Applications
Gabriela Jacques-Silva, Buğra Gedik, Rohit Wagle +2
Stream processing applications are deployed as continuous queries that run from the time of their submission until their cancellation. This deployment mode limits developers who ne…
Balancing Lifetime and Classification Accuracy of Wireless Sensor Networks
Kush R. Varshney, Peter M. van de Ven
Wireless sensor networks are composed of distributed sensors that can be used for signal detection or classification. The likelihood functions of the hypotheses are often not known…
