The Zeno effect occurs in quantum systems when a very strong measurement is applied, which can alter the dynamics in non-trivial ways. Despite being dissipative, the dynamics stay coherent within any degenerate subspaces of the measurement. The Zeno dynamics can theoretically transform a trivial (e.g., non-interacting with local control only) quantum system into one with universal control within the Zeno subspace. In this talk I will discuss how Zeno dynamics lead to universal control and show how such a measurement can turn a single-qubit operation into a two- or multi-qubit entangling gate, even in a non-interacting system. I will present our demonstration of such a gate between two effectively non-interacting superconducting qubits, and discuss the role of Zeno dynamics in realistic systems.
