Analytic Theory and cQED Implementation of a Two-Qubit Refrigerator: Sub-100 mK Cavity Cooling from a 4 K Bath
Daryoosh Vashaee, Jahanfar Abouie
We develop a theoretical framework for cooling a microwave cavity mode using a Poisson stream of internally correlated pairs of two-level systems and analyze its performance under…

Reservoir-Engineered Refrigeration of a Superconducting Cavity with Double-Quantum-Dot Spin Qubits
Daryoosh Vashaee, Jahanfar Abouie
We present an analytically tractable theory of reservoir-engineered refrigeration of a superconducting microwave cavity and map it onto a realistic solid-state implementation based…

Entanglement in Quantum Dots: Insights from Dynamic Susceptibility and Quantum Fisher Information
Jahanfar Abouie, Daryoosh Vashaee
This study investigates the entanglement properties of quantum dots (QDs) under a universal Hamiltonian where the Coulomb interaction between particles (electrons or holes) decoupl…
