  By modeling the stripe phase in cuprates as spin gapped stripes coupled to
the RVB liquid of preformed electron pairs, I derive the low energy effective
theory of the RVB phase variable. It is found that the effect of stripe
dynamics (including both longitudinal and transverse modes) leads to incipient
temporal phase stiffness in the RVB liquid, which tunes a quantum phase
transition toward a superconducting ground state with global phase order.
Physical consequences of this quantum criticality are discussed.
