A strongly coupled Quark–Gluon Plasma (sQGP) is created in the high-energy heavy-ion collisions at Relativistic Heavy-Ion Collider (RHIC) and Large Hadron Collider (LHC). Our present understanding of sQGP as a very good liquid with astonishingly low viscosity is reviewed. With the arrival of the interesting results from LHC in high-energy $p+p$ and $p+A$, a new endeavor to characterize the transition from these small systems to heavy ions $(A+A)$ is now in place, since even the small systems showed prominent similarities to heavy ions in the rising multiplicity domains. An outlook of future possibilities for better measurements is also made at the end of this brief review.

强耦合夸克-胶子等离子体 (sQGP) 在相对论重离子对撞机 (RHIC) 和大型强子对撞机 (LHC) 的高能重离子碰撞中产生。我们目前对 sQGP 的理解是一种非常好的液体，具有惊人的低粘度。随着 LHC 在高能领域的有趣结果的到来$磷+磷$ 和 $磷+\mathrm{一种}$，表征从这些小系统到重离子的转变的新尝试 $(\mathrm{一种}+\mathrm{一种})$现在已经到位，因为即使是小系统也显示出与增加的多重域中的重离子的显着相似性。本简短回顾的结尾还对未来进行更好测量的可能性进行了展望。
