Quantum Cryptography Companies

The global quantum cryptography market is projected to grow from USD 1.6 billion in 2025 to USD 10.2 billion by 2031 at a Compound Annual Growth Rate (CAGR) of 35.7% during the forecast period. Declining hardware costs, supported by scalable component manufacturing, improved photonic integration, and increased vendor competition, are lowering adoption barriers for organizations pursuing quantum-secure communication. At the same time, cloud-delivered quantum security services eliminate major upfront infrastructure investments, enabling flexible, subscription-based deployment and accelerating adoption among enterprises, telecom companies, and governments.

What is quantum cryptography?

MarketsandMarkets defines quantum cryptography as a field of cryptography that uses quantum mechanics principles to secure communications. Unlike classical cryptography, which relies on mathematical techniques to encrypt and decrypt messages, quantum cryptography uses the principles of quantum physics to create unbreakable codes. Quantum cryptography is based on the properties of quantum particles, such as photons, which can exist in multiple states simultaneously and can be used to transmit information in a way that is resistant to eavesdropping. By leveraging the principles of quantum entanglement and superposition, quantum cryptography allows two parties to share a secret key that is completely secure and cannot be intercepted by an eavesdropper.
