Significance We report that an unconventional superconducting state is formed at high pressure in UAu2. The high critical field required to suppress superconductivity and its unusual anisotropy suggest that the superconductivity has multiple components. A detailed analysis suggests that it could potentially host mobile half-quantum vortices. Mobile half-quantum vortices analogous to those seen in confined superfluid 3He have never been observed in a superconductor to date but could potentially be manipulated to make topologically protected quantum computations unaffected by decoherence.
