A Boundary Condition Perspective on Circuit QED Dispersive Readout
Mustafa Bakr
Boundary conditions in confined geometries and measurement interactions in quantum mechanics share a common structural role: both select a preferred basis by determining which stat…
Crosstalk Dispersion and Spatial Scaling in Superconducting Qubit Arrays
Mohammed Alghadeer, Simon Pettersson Fors, Shuxiang Cao +5
Crosstalk between qubits fundamentally limits the scalability of quantum processors, necessitating physics-based models that can handle the complexity of large qubit arrays. Here,…
Quantum Mechanics in a Spherical Wedge: Complete Solution and Implications for Angular Momentum Theory
Mustafa Bakr, Smain Amari
We solve the stationary Schrödinger equation for a particle confined to a 3D spherical wedge -- the region with D…
Double-Bracket Algorithmic Cooling
Mohammed Alghadeer, Khanh Uyen Giang, Shuxiang Cao +6
Algorithmic cooling shows that it is possible to locally reduce the entropy of a qubit belonging to an isolated ensemble such as nuclear spins in molecules or nitrogen-vacancy cent…
Intrinsic Multi-Mode Interference for Passive Suppression of Purcell Decay in Superconducting Circuits
Mustafa Bakr, Mohammed Alghadeer, Simon Pettersson Fors +6
Decoherence due to radiative decay remains an important consideration in scaling superconducting quantum processors. We introduce a passive, interference-based methodology for supp…
Long-Range Entangling Operations via Josephson Junction Metasurfaces
Mustafa Bakr
We present a framework for implementing two-qubit entangling operations between distant superconducting qubits using a space-time modulated Josephson junction metasurface. By modul…
Low Crosstalk in a Scalable Superconducting Quantum Lattice
Mohammed Alghadeer, Shuxiang Cao, Simone D Fasciati +5
Superconducting quantum circuits are a key platform for advancing quantum information processing and simulation. Scaling efforts currently encounter challenges such as Josephson-ju…
Characterization of Nanostructural Imperfections in Superconducting Quantum Circuits
Mohammed Alghadeer, Simone D Fasciati, Shuxiang Cao +7
Decoherence in superconducting quantum circuits, caused by loss mechanisms like material imperfections and two-level system (TLS) defects, remains a major obstacle to improving the…
