Latest Developments in Quantum Optics Based on Metasurfaces

This paper summarizes recent works on quantum optics based on micro/nano structures. Since its birth, quantum optics has been full of controversies with the locality and reality of classical physics versus the non-locality and uncertainty of quantum physics.

Scientists Find Clues Hinting at the Microscopic Sources of Qubit Information Loss

Engineers and materials scientists studying superconducting quantum information bits (qubits)-a leading quantum computing material platform based on the frictionless flow of paired electrons-have collected clues hinting at the microscopic sources of qubit information loss.

New Milky Way Disk Identified Using LAMOST-Gaia Data

At the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), astronomers have disclosed a wobbly, flared Milky Way disk using LAMOST-Gaia data, which updates one’s knowledge about the disk.

New Telescope Offers Hope to Explore Potential Life Around the Smallest Stars

The most powerful telescope in the world is scheduled to be launched into space this year. When that happens, researchers will be able to discover whether Earth-sized planets in the “solar neighborhood” have a vital precondition for life — an atmosphere.

Researchers Find Electrons to Move in Coordinated Ways in a Rare Quantum Material

A team led by the Department of Energy's Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially "dancing."

Solar System's Oldest Solids Could have Formed Further Away from the Sun than Previously Thought

The earliest solids formed in the solar system give clues to what radioactive species were made by the young sun, and which ones were inherited. By studying isotopic variations of the elements vanadium (V) and strontium (Sr), an international team of researchers including scientists from Lawrence Livermore National Laboratory found that those variations are not caused by irradiation from the sun but are produced by condensation and evaporation reactions in the early solar system.

Infrared Quantum Dot Lasing at Room Temperature for Quantum Communications

Lasers, devices that emit light in one direction, with photons traveling at one specific frequency and all with the same phase (coherent), govern the way we communicate today.

NUS and Thales Enter into a Partnership to Develop, Test Quantum Technologies

The National University of Singapore (NUS) and Thales have inked a Memorandum of Understanding (MoU) to mark the start of a two-year partnership to jointly develop and test quantum technologies for commercial applications.

Twisted Superconducting Flakes Show Potential to Outperform Components Used in Quantum Computers

Researchers at the University of Bath in the UK have found a way to make 'single-crystal flake' devices that are so thin and free of defects, they have the potential to outperform components used today in quantum computer circuits.

New Game App Takes Children and Teenagers into the Crazy Quantum World

Ding, dong. There is a box in front of the door. And inside there is ... a cute but half-dead cat! The main character of the new game app "Kitty Q" of the Würzburg-Dresden Cluster of Excellence ct.qmat–Complexity and Topology in Quantum Matter of the Universities of Würzburg and Dresden accompanies children and teenagers aged 11 and older into the crazy quantum world.

Researchers Discover a Bona Fide Topological Mott Insulator in Twisted Bilayer Graphene Model

Imagestacking two sheets of graphene – the 2D form of graphite, or the pencil at your hand – in which the carbon atoms form a hexagonal lattice and twist the top sheet out of alignment with the sheet below, yielding a periodic arrangement of atoms named moiré pattern.

Protecting or Nurturing Qubits by Using a Quantum Photonic Chip

Quantum states of particles are very fragile. The quantum bits, or qubits, that underpin quantum computing pick up errors very easily and are damaged by the environment of the everyday world.

Researchers Achieve High Energy Recovery from Multi-Turn Superconducting Linear Accelerator

The world’s first run of a multi-turn superconducting linear accelerator with substantial energy recovery was a success at Technische Universität Darmstadt.

Classical Physics Shed Light on New Phases of Matter

Researchers at the University of Cambridge have shown that complex many-body systems such as prethermal discrete time crystals (DTCs) do not need to be modeled using quantum mechanics. In fact, a computer simulation using classical Hamiltonian dynamics clearly demonstrated the properties of prethermal DTCs.
