Advancing resistivity-chargeability modeling for complex subsurface characterization using machine learning and deep learning
Adedibu Sunny Akingboye, Andy Anderson Bery, Hui Tang +4
Subsurface lithological heterogeneity presents challenges for traditional geophysical methods, particularly in resolving nonlinear electrical resistivity and induced polarization (…
Quantum nondemolition measurement operator with spontaneous emission
Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We present a theory for quantum nondemolition (QND) measurements of an atomic ensemble in the presence of spontaneous emission. We derive the master equation that governs the evolu…
Principal Component Analysis of Ground Level Enhancement of Cosmic Ray Events
R. E. Ugwoke, A. A. Ubachukwu, J. O. Urama +3
We applied principal component analysis (PCA) to the study of five ground level enhancement (GLE) of cosmic ray (CR) events. The nature of the multivariate data involved makes PCA…
Hybrid approximation approach to generation of atomic squeezing with quantum nondemolition measurements
Ebubechukwu O. Ilo-Okeke, Manikandan Kondappan, Ping Chen +3
We analyze a scheme that uses quantum nondemolition measurements to induce squeezing of a spinor Bose-Einstein condensate in a double well trap. In a previous paper [Ilo-Okeke et a…
Quality Assessment of the 20m SPOT DEM in Nigeria
Peter Nwilo, Johanson Onyegbula, Chukwuma Okolie +3
The 20m SPOT DEM (Digital Elevation Model) was acquired by the Office of the Surveyor-General of the Federation (OSGoF) in Nigeria for use in topographic mapping. A localized asses…
Positional Accuracy Assessment of Historical Google Earth Imagery
Peter C. Nwilo., Chukwuma J. Okolie, Johanson C. Onyegbula +6
Google Earth is the most popular virtual globe in use today. Given its popularity and usefulness, most users do not pay close attention to the positional accuracy of the imagery, a…
Deterministic preparation of supersinglets with collective spin projections
Ebubechukwu O. Ilo-Okeke, Yangxu Ji, Ping Chen +5
We introduce a procedure to generate supersinglets, the multipartite generalization of angular momentum singlet states. A supersinglet is defined as a total spin zero state consist…
Decoherence effects in quantum nondemolition measurement induced entanglement between Bose-Einstein condensates
Shuai Gao, Ebubechukwu O. Ilo-Okeke, Yuping Mao +4
We study the robustness of quantum nondemolition (QND) measurement-induced entanglement between Bose-Einstein Condensates (BECs). We consider an experimental scheme where two BECs…
Faraday imaging induced squeezing of a double-well Bose-Einstein condensate
Ebubechukwu O. Ilo-Okeke, Shinichi Sunami, Christopher J. Foot +1
We examine how non-destructive measurements generate spin squeezing in an atomic Bose-Einstein condensate confined in a double-well trap. The condensate in each well is monitored u…
GC-MS Profile of Diodella sarmentosa (SW) Bacigalupo El Cabral ex Borhidi Ethanol Leaf Extract and its Total Dehydrogenase Inhibitory Potential
Callistus Izunna Iheme, Doris Ifeyinwa Ukairo, Okechukwu Igwe Oguoma +4
Phytochemical composition of ethanol leaf extract of Diodella sarmentosa was profiled with GC-MS and the inhibitory property of the extract against total microbial dehydrogenases w…
Linear and nonlinear optical properties in spherical quantum dots: Inversely quadratic Hellmann potential
L. Máthé, C. P. Onyenegecha, A. -A. Farcaş +3
The aims of the reported work are to provide new insights into the quantum dot optical properties confined in an inverse of a quadratic Hellmann potential. The Schrödinger equation…
Remote state preparation of two-component Bose-Einstein condensates
Manish Chaudhary, Matteo Fadel, Ebubechukwu O. Ilo-Okeke +3
A protocol for remote state preparation is proposed for spin ensembles, where the aim is to prepare a state with a given set of spin expectation values on a remote spin ensemble us…
Harnessing Infant Cry for swift, cost-effective Diagnosis of Perinatal Asphyxia in low-resource settings
Charles C. Onu
Perinatal Asphyxia is one of the top three causes of infant mortality in developing countries, resulting to the death of about 1.2 million newborns every year. At its early stages,…
Relativity of quantum states in entanglement swapping: Violation of Bell's inequality with no entanglement
Chris Nagele, Ebubechukwu O. Ilo-Okeke, Peter P. Rohde +2
The entanglement swapping protocol is analyzed in a relativistic setting, where shortly after the entanglement swapping is performed, a Bell violation measurement is performed. Fro…
Remote quantum clock synchronization without synchronized clocks
Ebubechukwu O. Ilo-Okeke, Louis Tessler, Jonathan P. Dowling +1
A major outstanding problem for many quantum clock synchronization protocols is the hidden assumption of the availability of synchronized clocks within the protocol. In general, qu…
Lorentz invariant entanglement distribution for the space-based quantum network
Tim Byrnes, Batyr Ilyas, Louis Tessler +3
In recent years there has been a great deal of focus on a globe-spanning quantum network, including linked satellites for applications ranging from quantum key distribution to dist…
Information and backaction due to phase contrast imaging measurements of cold atomic gases: beyond Gaussian states
Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We further examine a theory of phase contrast imaging (PCI) of cold atomic gases, first introduced by us in Phys. Rev. Lett. {\bf 112}, 233602 (2014). We model the PCI measurement…
