Engineering Nanodevices to Store Information the Quantum Way
May 27, 2016
Stevan Nadj-Perge, Assistant Professor of Applied Physics and Materials Science, is interested in creating a device that could harness the power of entangled particles within a usable technology. A large part of his research is focused on finding ways to store and process quantum information. Quantum information is very fragile and even the smallest amount of external noise messes up quantum states. There are various schemes that tackle this problem and postpone decoherence, but the one that he is most interested in involves Majorana fermions. Relatively recently theorists figured out how to engineer these particles in the lab. Nadj-Perge explains, “it turns out that, under certain conditions, when you combine certain materials and apply high magnetic fields at very cold temperatures, electrons will form a state that looks exactly as you would expect from Majorana fermions. Furthermore, such engineered states allow you to store quantum information in a way that postpones decoherence.” [Caltech story]
