SUMMARY:Triangle Quantum Computing Seminar Series
DESCRIPTION:Join Today’s Duke\, NC State and UNC’s collaborative Triangle Quantum Computing Seminar \nTalk Title: Faster and More Reliable Quantum SWAPs via Native Gates \nSpeaker:  Pranav Gokhale\, Co-founder and CEO of Super.tech \nHosted by:  Duke Quantum Center \nAbstract:  Due to the sparse connectivity of superconducting quantum computers\, qubit communication via SWAP gates accounts for the vast majority of overhead in quantum programs. We introduce a method for improving the speed and reliability of SWAPs at the level of the superconducting hardware’s native gateset. Our method relies on four techniques: 1) SWAP Orientation\, 2) Cross-Gate Pulse Cancellation\, 3) Commutation through Cross-Resonance\, and 4) Cross-Resonance Polarity. Importantly\, our Optimized SWAP is bootstrapped from the pre-calibrated gates\, and therefore incurs zero calibration overhead. We experimentally evaluate our optimizations with Qiskit Pulse on IBM hardware. Our Optimized SWAP is 11% faster and 13% more reliable than the Standard SWAP. We also experimentally validate our optimizations on application-level benchmarks. Due to (a) the multiplicatively compounding gains from improved SWAPs and (b) the frequency of SWAPs\, we observe typical improvements in success probability of 10-40%. The Optimized SWAP is available through the SuperstaQ platform. \n  \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
