DESCRIPTION:Speaker: Onur Hosten\nAbstract: In the last decades\, advances 
 in the level of precision in controlling atomic and optical systems opened
  up the low-energy precision frontier to fundamental physics tests in addi
 tion to yielding new applied sensing technologies. In this talk I will foc
 us on our experiments with cold atoms highlighting some of the most recent
  developments in the prospect of using quantum entanglement to further imp
 rove the precision of atomic and optical sensors.\nI will describe the gen
 eration of 20dB spin-squeezed states of half a million 87Rb atoms inside o
 f an optical cavity. From a practical point of view\, the generated states
  enable up to a 100-fold reduction in required averaging times or atom num
 bers to achieve a given precision. I will explain the implementation of an
  atomic clock operating 10 dB beyond the standard quantum limit as well as
  the investigations of entanglement and Bell correlations in this system. 
 I will then describe the demonstration of a new concept we call quantum ph
 ase magnification which utilizes optical cavity-aided interactions between
  atoms to magnify signals to-be-measured. This technique eliminates the ne
 ed for low noise detection to achieve phase sensitivities beyond the stand
 ard quantum limit.
