New quantum matters:Build up versus high pressure tuning

In this article we briefly review new quantum functional compounds primarily based on our recent works. We will highlight the effects of pressures on both materials synthesis and quantum tuning. The contents include （I） ＂111＂-type iron based super- conducting system, （II） pressure induced superconductivity in topological insulators and （II/） the new diluted magnetic semi- conductors with decoupled spin charge doping.
