In a new study, researchers from the Max Planck Institute of Quantum Optics under the lead of Timon Hilker demonstrated evidence of stripe formation, i.e. extended structures in the density pattern, in a cold-atom Fermi-Hubbard […]
Legitimate quantum operations must adhere to principles of quantum mechanics, particularly the requirements of complete positivity and trace preservation. Yet, non-completely positive maps, especially Hermitian-preserving maps, play a crucial role in quantum information science. Researchers […]
Optical quantum communication technologies are making the prospect of unconditionally secure and efficient information transfer a reality. The possibility of generating and reliably detecting quantum states of light, with the further need of increasing the […]
Scientists propose a fault-tolerant scheme for generating long-range entanglement at the ends of a rectangular array of qubits of length R. It is realized by a constant-depth circuit producing a constant-fidelity Bell-pair (independent of R) for local […]
Fast and high-fidelity qubit measurement is essential for Quantum Error Correction (QEC) in universal quantum computing. This study examines dispersive measurement of a spin in a semiconductor double quantum dot using a nonlinear microwave resonator. […]
UC Santa Barbara researchers have developed a breakthrough in laser technology: a compact, chip-scale laser that matches or exceeds the performance of much larger laboratory systems while being significantly more affordable. Led by Professor Daniel […]
Large-scale communication networks, such as the Internet, rely on routing packets of data through multiple intermediate nodes to transmit information from a sender to a receiver. Researchers has developped a model of a quantum communication […]
Northwestern University engineers have accomplished a significant feat by successfully demonstrating quantum teleportation through fiber optic cables while simultaneously carrying regular Internet traffic. Led by Professor Prem Kumar, the team published their findings in Optica […]
Researchers at the University of Chicago’s Pritzker School of Molecular Engineering have developed a groundbreaking quantum processor design that challenges traditional computational architectures. Unlike conventional quantum chips that arrange qubits in rigid 2D grids, this […]
The groundbreaking study by Rice University physicist Qimiao Si delves into the fascinating world of quantum critical metals, materials that defy conventional physics by exhibiting extraordinary behavior at low temperatures. Published in Nature Physics, the […]
