Quantum-Device Simulation of Optical Decoherence of Hole-Spin Qubits in Self-Assembled Quantum Dots
Jyun-Jie Jiang, Pericles Philippopoulos, Félix Beaudoin +1
Spin-photon interfaces are essential for communications between distant spin qubits in quantum technologies, but the interband optical excitation can also damp electrically driven…
First-principles predictions of band alignment in strained Si/Si1-xGex and Ge/Si1-xGex heterostructures
Nathaniel M. Vegh, Pericles Philippopoulos, Raphaël J. Prentki +4
The paper uses first‑principles density functional theory to calculate composition‑dependent valence and conduction band offsets in strained Si/Si₁₋ₓGeₓ and Ge/Si₁₋ₓGeₓ heterostruc…
Analysis of Hydrogen Contamination in Al/AlOx/Al Josephson Junctions
Yu Zhu, Aldilene Saraiva-Souza, Félix Beaudoin +1
Hydrogen contamination in Josephson junctions is a potential source of device-to-device variability and two-level-system loss in superconducting qubits. In this work, we investigat…
Constraints on Atomistic Disorder for Scalable Electron Spin Shuttling
Raphaël J. Prentki, Raphaël J. Prentki, Pericles Philippopoulos +3
Electron spin shuttling, the gate-controlled, coherent transport of electrons between qubit registers, increases qubit connectivity and enables efficient quantum-error-correction s…
