Quantum spin liquids (QSLs) are long-range entangled states of matter of billions of interacting qubits or spins that develop in a Mott insulator. Remarkably QSLs harbor fractionalized excitations rather than the conventional spin waves of ordered magnets that carry integer units of angular momentum. In my talk I will discuss possible implementation of these frustrated Hamiltonians using Rydberg atoms. I will identify detectable signatures of these fractionalized excitations in pump-probe spectroscopy. These fractionalized excitations are promising candidates to create logical qubits for quantum computation.

Nandini Trivedi is a Professor of Physics and a Distinguished Professor of the College of Arts and Sciences at the Ohio State University.
Trivedi got her undergraduate degree from the Indian Institute of Technology, Delhi and a Ph.D in physics in 1987 from Cornell University. After post-doctoral research at University of Illinois at Urbana-Champaign and State University of New York, Stony Brook, she joined Argonne National Laboratory as a staff scientist. In 1995 she joined the faculty of the Tata Institute of Fundamental Research, Mumbai. Since 2004 she has been a professor of physics at the Ohio State University.
Trivedi’s research is in understanding emergent phases in quantum matter due to strong correlations and topology.
