Experimental realization of phase-controlled dynamics with hybrid digital–analog approach

Quantum simulation can be implemented in pure digital or analog ways, each with their pros and cons. By taking advantage of the universality a route efficiency simulation, hybrid digital-analog approaches enrich possibilities for quantum simulation. We use unique approach to experimentally perform phase-controlled dynamics resulting from closed-contour interaction (CCI) within certain multi-level systems superconducting circuits. Due symmetry constraints, such cannot host an inherent CCI. Nevertheless, by assembling modules corresponding natural evolutions specially designed constructed standard logic gates, we bypass constraints realize effective CCI these systems. Based on this realization, demonstrate variety related interesting phenomena, including chiral dynamics, separation enantiomers, new mechanism generate entangled states based
