With support from Q-NEXT, a group of Stanford University researchers are creating new possibilities for #quantum networking by boosting the signal from tin atoms embedded in diamond. ➡️ https://bit.ly/4h94obd
The future of tin-based qubits is brighter thanks to breakthrough work by Stanford University researchers supported through Q-NEXT. 🔗 https://lnkd.in/gr2ndEGx The Stanford team achieved their milestone on a type of #qubit known as a tin vacancy center in diamond: replace two of diamond’s carbon atoms with one atom of tin and voila! A tin vacancy qubit is born. But of course, it isn’t so simple. A tin vacancy qubit can be in one of two states: spin-up and spin-down. That spin signal tends to be fuzzy and hard to read, making tin vacancies less useful than other qubit types for transmitting information. But the Stanford team has now turned things around. As detailed in Physical Review X, the group successfully boosted the tin vacancy qubit’s signal, reading its spin state with an impressive 87% accuracy. Typical tin vacancy measurements require averaging hundreds of readings. But the Stanford group was able to read the qubit’s spin state in a single shot. The high-accuracy, single-shot readout of the signal with reliable spin control is a first for tin-vacancy qubits. The research was led by Jelena Vuckovic, the Jensen Huang professor of global leadership, professor of electrical engineering and by courtesy of applied physics at Stanford. ⚛️ Read more to hear from two of the scientists, Souvik Biswas and Eric Rosenthal: https://lnkd.in/gr2ndEGx #quantuminformationscience #quantumscience #quantummaterials
