A physicist who coauthored a study of experimentally controlled dephasing in a qubit. Its optical platform simulates how coupling to an environment changes coherence, including dynamics inspired by a Transverse-field Ising model. This provides an experimental way to compare environment models and their consequences for quantum decoherence.[ref]
Experimental implementation of fully controlled dephasing dynamics and synthetic spectral densities by Zhao-Di Liu and others. Abstract and simulation of an Ising-chain environment
