Quantum Cryptography
Quantum Cryptography The Quantum Threat to Cybersecurity Today’s RSA (Rivest–Shamir–Adleman) encryption, a widely used form of encryption, particularly used for encrypting data on personal and professional on internet, is based on 2048-bit numbers. Experts guess that a quantum computer would need to be as large as 60 to 70 million qubits to break the RSA encryption. Considering the largest quantum computer in todays world is 53-qubit quantum computer, for breaking today encryption quantum computer need more qubit so in present it is not threat but in future it might be threat for cybersecurity. As the speed of quantum research continues to accelerate, though, the development of such a computer within the next 4-6 years cannot be ignored. example In 2018 Google and the KTH Royal Institute of Technology in Sweden r...
