SUMMARY:Science & Cocktails #25 : Certified Quantum Randomness
DESCRIPTION:[vc_row][vc_column][vc_column_text]Randomness is a phenomenon w
 hich we are confronted with all the time. Will it rain today? Will the tra
 in be on time? What present will I receive at Christmas? But are such phen
 omena truly random?\n\nGood randomness is essential for many applications.
  For instance\, cryptography\, the art of hiding information from maliciou
 s parties\, is only as good as the sources of randomness that underlie it.
 \n\nQuantum mechanics\, the theory of microscopic phenomena\, can only pre
 dict the probability of events. For instance quantum theory can only predi
 ct the probability that a radioactive nucleus will decay\, not when the nu
 cleus will decay. Does this mean that microscopic phenomena are truly rand
 om?\n\nBy studying systems of two entangled particles\, it can be shown bo
 th theoretically and experimentally that events at the microscopic scale a
 re truly random\, truly unpredictable. Beyond its philosophical implicatio
 ns\, this result also has important potential applications. Indeed\, it im
 plies that one can build random number generators that certify that they w
 ork correctly. That is\, if the random number generator malfunctions in so
 me way\, if the numbers it produces cease to be random\, this will automat
 ically be detected. By extending this idea\, one could also build quantum 
 cryptographic systems and quantum computers that certify that they work co
 rrectly.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width="1/
