Say Alice has a string x of length n (EXAMPLE: x=0111 and n=4). Say Bob has a string y of length n They want to know if x=y. Alice could just say HEY BOB, MY STRING is x, and Bob could shout back either YES x=y or NO x is NOT y. This would require communication n bits. This could be A LOT of bits (say if x is the collected works of Shakespeare). Can they determine if x=y while communication FAR less bits. Come to the talk to find out!
