Cryptography Without Using Secret Keys – White Paint as an Unclonable Key
Most security applications, for instance, access to buildings or digital signatures, use cryptographic keys that must at all costs be kept secret. That also is…
Scientists Create ‘Universal Entangler’ for New Quantum Tech
One of the key concepts in quantum physics is entanglement, in which two or more quantum systems become so inextricably linked that their collective state…
Researchers Create Frequency Comb to Encrypt Data and Protect Cryptocurrencies
Data travels through thousands of miles of fiber optic cables underneath the world’s oceans–via pulses of light. And according to experts, the data in these…
Breakthrough in Quantum Cryptography Demonstrates “Perfectly Secure” Bit Commitment
For the first time, researchers have demonstrated perfectly secure bit commitment, sending encrypted data between pairs of sites in Geneva and Singapore. A breakthrough in…
Encoded Photons Using Quantum Cryptography Sent a Record Distance
Quantum encryption systems, which encode signals into a series of single photons, have had trouble sending them along optical fibers. Until now, it has been…
