Computing uncertainty
WebQuantum cryptography uses the laws of quantum physics to transmit private information in a way that makes undetected eavesdropping impossible. Quantum key distribution (QKD), the most widely studied and viable method of quantum cryptography, uses a series of photons to transmit a secret, random sequence, known as the key. Webuncertainty of 1 mm. Clearly you know more about the length of the table than the width of the hair. Your measurement of the table is very precise but your measurement of the width of the hair is rather crude. To express this sense of precision, you need to calculate the percentage uncertainty. To do this, divide the
