Abstract
Quantum Zeno effect is a significant tool in quantum
manipulating and computing. We propose its observation in
superconducting phase qubit with two experimentally feasible
measurement schemes. The conventional measurement method is used to
achieve the proposed pulse and continuous readout of the qubit
state, which are analyzed by projection assumption and Monte Carlo
wave-function simulation, respectively. Our scheme gives a direct
implementation of quantum Zeno effect in a superconducting phase
qubit.
