Quantum Effects in Nanotechnology & Emerging Devices
Handel pioneered analysis of quantum 1/f noise in nanoscale and quantum devices including quantum dots, nanowires, molecular electronics, spintronic devices, quantum well photodetectors, resonant tunneling diodes, and quantum computing elements. His research (1998-present) on the quantum 1/f proximity effect showed that noise in closely-spaced nanostructures depends on separation distance through quantum entanglement, while his work on decoherence demonstrated that quantum 1/f noise represents a fundamental limit on qubit coherence times.
This work fundamentally changed the roadmap for nanoelectronics and quantum technology by demonstrating that Moore's Law scaling faces fundamental quantum noise barriers independent of fabrication capabilities, establishing ultimate size limits for classical devices while simultaneously providing optimization strategies for quantum devices that exploit rather than fight quantum mechanical effects.
