Transmitting entanglement between light and matter in the metropolitan network of Barcelona
Measurement of non-classical correlations between remote locations. Map of the metropolitan area of Barcelona, with the three locations highlighted: ICFO, where the memory and SPDC source are located; CTTI, where…
One degree above absolute zero
Credit: Diraq For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or –273.15°C).…
Realizing clean qubits for quantum computers using electrons on helium

A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations
A view of the honeycomb lattice, with a triangular region indicated with the black sites (spheres). The electrons in the model studied by the researchers can jump between sites of…
Small-scale solution could be key to solving large-scale mystery
(Left) The new dark matter detection proposal looks for frequent interactions between nuclei in a detector and low-energy dark matter that may be present in and around Earth. (Right) A…
