An unconventional monetary policy that ultimately leads to inflation. Central banks tend to use quantitative easing when interest rates have already been lowered to near 0% levels and have run out of other options to stimulate an economy. The basic mechanism for quantitative easing is the buying of government securities or other securities from the market.
for example:
The central bank creates money which it uses to buy government bonds and other financial assets, in order to increase the money supply and the excess reserves of the banking system; this also raises the prices of the financial assets bought (which lowers their yield).
