Design of integrated photonic controlled-phase gate with programmable phase for quantum applications
Basay, Yalin; Kocaman, Serdar (2022-01-01)
© 2022 SPIE.Photons are preferable carriers of quantum information having little interaction with environment. Most crucial elements of photonic quantum information processing are two qubit gates. Although usage of control...
A numerical design for SWIR/eSWIR dual-band operation with InGaAs nBn structures
Şahin, Alper; Gül, Musa Selim; Uzgur, Fatih; Kocaman, Serdar (2022-01-01)
In this paper, we present an nBn type dual-band InGaAs photodetector design with bias selectable cut-off wavelengths of 1.7 mu m and 2.5 mu m. InP based epilayer design consists of a compositionally graded quaternery InAlG...
Association and Fusion of Range-Azimuth Tracks
Balci, Ali Emre; Şahin, Kurtuluş Kerem; Kumru, Firat; Pektas, Fatih; Özkan, Emre; Orguner, Umut (2022-01-01)
In this paper, novel association and fusion methods for range-azimuth tracks are proposed. The association method requires calculating the distance between two tracks that lack elevation information. An iterative algorithm...
Privacy Signaling Games with Binary Alphabets
Stavrou, Photios A.; Sarıtaş, Serkan; Skoglund, Mikael (2022-01-01)
In this paper, we consider a privacy signaling game problem for binary alphabets and single-bit transmission where a transmitter has a pair of messages, one of which is a casual message that needs to be conveyed, whereas t...
Generalized Model of Modular Two Element Compensated IPT Systems with Common DC-Bus
Ayaz, Enes; Altun, Ogün; Polat, Hakan; Keysan, Ozan (2022-01-01)
In this paper, modular IPT systems which have receiver series/parallel compensation with series/parallel common DC-Bus are investigated. For these systems, power sharing between the receiver modules is vulnerable to system...
A Model Selection criterion for the Mixture Reduction problem based on the Kullback-Leibler Divergence
D'Ortenzio, Alessandro; Manes, Costanzo; Orguner, Umut (2022-01-01)
In order to be properly addressed, many practical problems require an accurate stochastic characterization of the involved uncertainties. In this regard, a common approach is the use of mixtures of parametric densities whi...
