  • Quantum communications is expected to be commercially available much before other quantum computing (QC) applications.

  • Quantum key distribution enables two distant parties to communicate securely with each other using a sequence of quantum-mechanically shared secret bits called the key.

  • Several companies have brought quantum random number generators (QRNGs) into the market, offering different features in terms of bit rate and connectivity.
  • QRNGs find essential application in cryptography, simulations, and lotteries, and thus would cater to various industries, including automotive, smart networks and devices, gaming, and finance.
  • Considering quantum cryptography as a potential business opportunity, several research initiatives, partnerships between different organizations, and commercial solutions have been announced in recent years.
