We have been under the assumption that the encryption that protects our bank accounts, patient records, and government ...

Quantum key distribution (QKD) has been positioned as a physics-based method of securing encryption keys that cannot be intercepted without detection and as a critical technology for ensuring ...

The ability to send quantum information securely, known as quantum key distribution, is one of the most practical (if difficult) applications of quantum science. A new study demonstrates the ...

The rise of quantum computing introduces risks to classical encryption systems, emphasizing the need for more resilient alternatives. Post-quantum cryptography (PQC) offers a practical short- to ...

The experimental layout of the sender Alice and the receiver Bob. Alice’s setup contains the excitation and collection setup of the single photon source, and a Sagnac-like polarization modulator for ...
