The global quantum encryption market was valued at USD 550 million in 2024 and grew at a CAGR of 33% from 2025 to 2034. The market is expected to reach USD 9,525.31 million by 2034. The rising applications of quantum computing will drive the growth of the global quantum encryption market.
Quantum encryption makes use of the basic ideas of quantum mechanics to make communication much safer than current methods. Essentially, quantum encryption depends on Quantum Key Distribution (QKD). With QKD, two parties are able to make and exchange a cryptographic key across a quantum channel. Quantum superposition and the no-cloning theorem make sure that the process is secure, as stated by quantum physics laws. When a third party tries to get the key using a quantum system, the key will be affected and the intrusion would be instantly noticed. Two communication parties use quantum bits (qubits), sent using photons’ polarization or phase, in QKD. Among QKD protocols, BB84 and E91 are the leading examples, made to stop hackers from reading any shared keys. When the key is safe, it is possible to use conventional encryption like the one-time pad for encrypting messages with total privacy. More and more attention is being given to quantum encryption because the rise of quantum computers may break most of today’s classical encryption schemes. The ability of quantum computers to compute certain problems very quickly makes today’s cryptography code easily breakable. The technology has come up with a new kind of security that depends on nature and not on computing, so quantum encryption can withstand all future risks.
