Query: Demonstration of universal control between non-interacting qubits using
  the Quantum Zeno effect   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. Here we show that such a measurement can turn a single-qubit
operation into a two- or multi-qubit entangling gate, even in a non-interacting
system. We demonstrate this gate between two effectively non-interacting
transmon qubits. Our Zeno gate works by imparting a geometric phase on the
system, conditioned on it lying within a particular non-local subspace. These
results show how universality can be generated not only by coherent
interactions as is typically employed in quantum information platforms, but
also by Zeno measurements.
