The University of Stuttgart, in collaboration with Saarland University and Leibniz IFW Dresden, successfully deployed an entanglement-based quantum key distribution (QKD) link using a quantum dot photon source. The system generated 14.2 Mbit of secure key material over a 1.59 km fiber link, achieving one-time pad image encryption. This demonstrates…
Physicists at Chalmers University of Technology have developed a new method to eliminate microwave crosstalk in superconducting processors. Their research shows that by engineering on-chip parasitic capacitances, they can achieve destructive interference among parasitic capacitive channels, suppressing unwanted qubit excitations. This method offers a practical advantage for floating transmons and…
Researchers from Los Alamos National Laboratory and QC Ware developed a hybrid quantum-classical workflow to simulate strongly correlated transition metal oxides. They used Sample-based Quantum Diagonalization (SQD) on IBM Quantum hardware, coupled with ab initio-informed d–p tight-binding models, to achieve chemical accuracy in modeling diatomic iron monoxide (FeO) and rhombic…
