Speaker:Â Michael Foss-Feig (Quantinuum) Title:Â Probing critical states of matter on a quantum computer Abstract:Â I will describe Quantinuumâ€™s trapped ion QCCD quantum computers, with a particular focus on the key technical challenges and solutions for realizing mid-circuit measurement and reuse of qubits. In addition to the importance these capabilities play in quantum error correction, they also afford remarkable efficiencies in simulating many-body physics, enabling explorations of physics at length scales well beyond the limits that would be naively guessed from the size of present-day quantum computers. I will discuss recent work utilizing quantum implementations of hierarchical tensor networks to represent critical ground states of spin chains on Quantinuumâ€™s H1 series quantum computers, demonstrating that current quantum computing hardware is already capable of extracting accurate estimates of critical properties of infinite systems. *Lunch will be served after the seminar only to the individuals that have attended*
At 4pm, there will be a tea inÂ ATL 2117 for our speaker and students/postdocs -Â thisÂ is a chance to ask questions directly to our speaker. Refreshments will be served.
