Entropy Transport in Programmable Quantum Junctions
Radhika Joshi, Yuli V. Nazarov, Mohammad H. Ansari
We show that driven qubit junctions enable programmable control of physical entropy transport, with entropy conductance governed by quantum dynamics rather than by reservoir parame…

Parity Cross-Resonance: A Multiqubit Gate
Xuexin Xu, Siyu Wang, Radhika Joshi +2
We present a native three-qubit entangling gate that exploits engineered interactions to realize control-control-target and control-target-target operations in a single coherent st…

Information Transport in Classical-Quantum Hybrid System
Julian Rapp, Radhika H. Joshi, Alwin van Steensel +2
Many important quantities in quantum information science, such as entropy and entanglement, are non-linear functions of the density matrix and cannot be expressed as operator obser…
