    The {QUIJOTE} (Q-U-I {JOint} Tenerife) {CMB} Experiment is designed to observe the polarization of the Cosmic Microwave Background and other Galacticand extragalactic signals at medium and large angular scales in thefrequency range of 10-40 {GHz}. The first of the two {QUIJOTE} telescopesand the multi-frequency (10-20 {GHz}) instrument have been in operationsince November 2012. In 2014 a second telescope and a new instrument at30GHz will be ready for commissioning, and an additional instrument at40 {GHz} is in its final design stages. After three years of effectiveobservations, the data obtained by these telescopes and instruments willhave the required sensitivity to detect a primordial gravitational-wavecomponent if the tensor-to-scalar ratio is larger than r = 0.05. At themoment, we have completed half of the wide Galactic survey with themulti-frequency instrument covering 18 000 square degrees of theNorthern hemisphere. When we finish this survey in early 2014, we shallhave reached approximately 14\{{\textbackslash}mu\}K per one degree beam at 11, 13, 17and 19 {GHz}, in both Q and U.
