Qiskit Seminar Series Episode 124 with Volodymyr Sivak Quantum Error Correction Beyond Break-Even Your formal invite to weekly Qiskit videos ► https://ibm.biz/q-subscribe This is Vlad's second time on the seminar, he was one of our earliest guests back in 2020! https://www.youtube.com/live/HnF7iGA0H-0?feature=share Speaker: Volodymyr Sivak Host: Derek Wang Abstract: Decoherence is a fundamental phenomenon through which classical behavior emerges from the quantum laws of nature. It is the main obstacle to harnessing these laws for information processing. Quantum error correction (QEC) is a process that allows to protect quantum information from decoherence. Previous experimental attempts to engineer such a process faced the generation of an excessive number of errors that overwhelmed the error-correcting capability of the process itself. In the recent experiment [Nature 616, 50-55 (2023)], we showed for the first time that QEC really works in practice. We used it to extend the lifetime of quantum information by more than 2x. Bio: I am from Ukraine, did my undergrad at Moscow Institute of Physics and Technology, then a PhD at Yale University in the group of Michel Devoret. During my time at Yale, I worked on quantum-limited amplifiers, applications of reinforcement learning to quantum control, and quantum error correction of the oscillator grid code (aka Gottesman-Kitaev-Preskill code). Now I am a research scientist at Google Quantum AI, working on the optimization of the quantum processor for the surface code.
