| Abstract Scope |
Quantum technologies promise revolutionary advances in computing, communication, and sensing, yet their widespread deployment remains limited by challenges in scalability, energy consumption, and device integration. Quantum diodes, which exhibit nonreciprocal quantum transport with/without external magnetic fields, have recently emerged as a promising platform for overcoming these challenges. By enabling dissipationless directional transport and programmable nonreciprocity, quantum diodes offer new opportunities for low-power quantum circuits and scalable quantum information processing. In this talk, I will present recent advances in superconducting and skyrmion quantum diodes and discuss their fundamental properties. I will also discuss how quantum diodes can be integrated into circuits to reduce circuit complexity, suppress energy dissipation, and enable more efficient quantum control. |
