A Quantum Defect Moves Into Ordinary Oxide
Simulations identified a molybdenum-and-vacancy defect in zinc oxide with properties suited to spin readout and quantum light.
Summary
Simulations identified a molybdenum-and-vacancy defect in zinc oxide with properties suited to spin readout and quantum light.
Researchers computationally screened point defects in zinc oxide and identified a molybdenum atom beside a missing oxygen as a promising spin-qubit design. Their first-principles calculations predict sharp visible emission, a spin coherence time near four milliseconds, and the ingredients for single-shot readout. Zinc oxide is compatible with established semiconductor growth, but the work is a theoretical design: the defect still must be fabricated and measured.
