SUMMARY:First Triangle Quantum Computing Seminar Series for Spring 2022
DESCRIPTION:Join Today’s Duke\, NC State and UNC’s Collaborative Quantum Computing Seminar \nNEW TIME: Seminars will be held each Friday this Spring from 2pm – 3pm\nTalk Title: Interactive Protocols for Classically-Verifiable Quantum Advantage with an Ion-Trap\nQuantum Computer \nSpeaker:   Daiwei Zhu \nAbstract: \nThe recent demonstrations of quantum advantage with superconducting and linear optics devices have highlighted both the impressive capabilities of near-term quantum computers but also the limitations in being able to verify the results in a scalable manner. This is because current experiments have focused on (classically-hard) sampling tasks which\, while relatively easy to implement in hardware\, require exponential time to validate their results. A way to overcome the intractability of verification is with interactive proofs of quantumness—protocols that leverage cryptographic functions as well as interactions between a prover and a verifier\, to bridge the gap between verifiability and implementation. \nIn this talk\, we present the first implementation of such an interactive test of quantum advantage on an ion-trap quantum computer. This consists of two complementary protocols—one based on the hardness of factoring\, which implements a type of computational Bell test and another based on the learning with errors (LWE) problem. To perform multiple rounds of interaction\, we used a split-and-shuttle approach to realize mid-circuit measurements on selected subsystems\, with subsequent coherent evolution. For both protocols\, the experimental results exceed the asymptotic bound for classical behavior; maintaining this fidelity at scale would conclusively demonstrate verifiable quantum advantage. \nThis is a Hybrid Event with NC State. \nThe In Person location for NC State is Venture Place\, 2nd Floor\, Large Classroom. \nREGISTRATION: Form Link  \nFor more information email:  quantumcomputing@ncsu.edu
