A new study by Hebrew University has made a significant breakthrough by successfully incorporating single-photon sources into small chips that operate at room temperature. This…
The power of the second law The second law of thermodynamics is widely considered one of the most universally true physical laws. It dictates that…
An improved version of quantum key distribution. The Internet is filled with highly sensitive data. In general, sophisticated encryption techniques guarantee that such material cannot…
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…
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…
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…
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…
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…
