Programmable quantum circuits in a large-scale photonic waveguide array
A team has reported on the first demonstration of precise control of single photon states on an 11-dimensional continuously-coupled programmable waveguide array.
Breakthrough in Quantum Dot Metamaterials
Researchers at the University of Groningen led by Professor Maria Antonietta Loi have successfully created a highly conductive optoelectronic metamaterial by developing a method for quantum dots to self-organize into a three-dimensional superlattice that maintains their unique optical characteristics while achieving unprecedented electron mobility.
A scheme to create and verify scalable entanglement in optical lattice
The research proposes a novel scheme for generating scalable quantum entanglement using ultracold atoms in optical superlattices, where atoms are sequentially entangled in double wells and then reconfigured through lattice phase shifts, resulting in a noise-resistant genuine multipartite entangled state suitable for practical quantum computing implementations.
