Regularized Distributed MPC for UAV Networks: Stabilizing Coupled Motion and Hybrid Beam Alignment
Evangelos Vlachos
This letter investigates the coupled control problem in UAV networks utilizing high-frequency hybrid beamsteering. While phased arrays enable rapid electronic scanning, their finit…
Receiving RISs: Enabling Channel Estimation and Autonomous Configuration
George C. Alexandropoulos, Konstantinos D. Katsanos, Evangelos Vlachos
This chapter focuses on a hardware architecture for semi-passive Reconfigurable Intelligent Surfaces (RISs) and investigates its consideration for boosting the performance of Multi…
Beating the Ramsey limit on sensing with deterministic qubit control
M. O. Hecht, Kumar Saurav, Evangelos Vlachos +2
Quantum sensors promise revolutionary advances in medical imaging, energy production, mass detection, geodesy, foundational physics research, and a host of other fields. In many se…
SQuADDS: A validated design database and simulation workflow for superconducting qubit design
Sadman Shanto, Andre Kuo, Clark Miyamoto +6
We present an open-source database of superconducting quantum device designs that may be used as the starting point for customized devices. Each design can be generated programmati…
On-demand driven dissipation for cavity reset and cooling
Vivek Maurya, Haimeng Zhang, Daria Kowsari +9
We present a superconducting circuit device that provides active, on-demand, tunable dissipation on a target mode of the electromagnetic field. Our device is based on a tunable "di…
Time-Domain Channel Estimation for Extremely Large MIMO THz Communication Systems Under Dual-Wideband Fading Conditions
Evangelos Vlachos, Aryan Kaushik, Yonina C. Eldar +1
In this paper, we study the problem of extremely large (XL) multiple-input multiple-output (MIMO) channel estimation in the terahertz (THz) frequency band, considering the presence…
