Today’s quantum computers contain up to several dozen memory and processing units, the so-called qubits. Researchers from the Max Planck Institute of Quantum Optics have successfully interconnected two such qubits located in different labs to
A team of researchers has investigated transmon qubits made from semiconductor nanowires with a fully surrounding superconducting shell. In the regime of reentrant superconductivity associated with the destructive Little-Parks effect, numerous coherent transitions are observed
Continuous-Variable Quantum Key Distribution (CV-QKD) enables information-theoretically secure key exchange between two parties using the continuous-variable properties of the quantized electromagnetic light field. The secret key rate of a CV-QKD system is limited by excess
A European consortium was launched today with the goal of scaling silicon quantum technologies. Named QLSI (Quantum Large-Scale Integration with Silicon), this four-year EU project, coordinated by CEA-Leti, will lay the foundation for the EU’s
Researchers at the US Army Research Laboratory have built a quantum sensor, which can sample the radio-frequency spectrum—from zero frequency up to 20 GHz—and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals. The Rydberg
