Practical application possibilities

Cryptography

Cryptography is the specialist term for the encryption of data. In the age of the Internet and the hacker, it is becoming increasingly important to protect data from unauthorised access before transmission. For banks too, one interesting possibility is to use the invisible connection existing between twin photons:

  On the world's first quantum-cryptographically encrypted bank transfer. Vienna physicists under Anton Zeilinger carried out the transfer using "spooky photons" . . .

Quantum computers

Twin photons will revolutionise the design and manufacture of computers. These so-called quantum computers will be able to handle computing processes several times faster than the processors available today:
