Quantum information is a powerful technology for increasing the amount of information that can be processed and communicated securely. Using quantum entanglement to securely distribute a secret quantum state among multiple ...
How can we combat data theft, which is a real issue for society? Quantum physics has the solution. Its theories make it possible to encode information (a qubit) in single particles of light (a photon) and to circulate them ...
Self-testing is a promising method to infer the physics underlying specific quantum experiments using only collected measurements. While this method can be used to examine bipartite pure entangled states, so far it could ...
Researchers and engineers from QuTech and Eindhoven University of Technology have created Majorana particles and measured their properties with great control.
A study by Oak Ridge National Laboratory researchers has demonstrated how satellites could enable more efficient, secure quantum networks.
Researchers at the Kastler Brossel Laboratory in Paris have succeeded in building the first converter between the two different types of quantum-bit encodings—an equivalent to converters for classical information, but targeted ...
Thirteen, 53 and 433. That's the size of quantum computers in terms of quantum bits, or qubits, which has significantly grown in the last years due to important public and private investments and initiatives. Obviously, it ...
A team of researchers has developed an on-chip photon-counting device that could significantly advance numerous applications of quantum technology.
In the digital era and moving towards quantum computing, protecting data against hack attacks is one of our biggest challenges—and one that experts, governments, and industries worldwide work hard to address. While this is ...
