Encyclopedia

Particle is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Particles can also be used to create scientific models of even larger objects depending on their density, such as humans moving in a crowd or celestial bodies in motion. — Wikipedia

Science

Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word particle can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), particle physics usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behavior. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. — Wikipedia

  • A new way to count qubits
    on September 24, 2018 at 3:50 pm

    Researchers at Syracuse University, working with collaborators at the University of Wisconsin (UW)-Madison, have developed a new technique for measuring the state of quantum bits, or qubits, in a quantum computer. […]

  • Explainer: The US push to boost 'quantum...
    on September 24, 2018 at 2:17 pm

    A race by U.S. tech companies to build a new generation of powerful "quantum computers" could get a $1.3 billion boost from Congress, fueled in part by lawmakers' fear of growing competition from China. […]

  • On-demand room-temperature single photon...
    on September 21, 2018 at 12:47 pm

    Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. […]

    on September 21, 2018 at 10:52 am

    The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved nearly freely in a quark-gluon plasma. Then, in a phase […]

  • Quantum anomaly—breaking a classical symmetry...
    on September 20, 2018 at 11:34 am

    A FLEET study of ultracold atomic gases—a billionth the temperature of outer space—has unlocked new, fundamental quantum effects. The researchers at Swinburne University of Technology studied collective oscillations in ultracold atomic gases, identifying where quantum effects occur to break symmetries predicted by classical physics. They also observed the transition between two-dimensional (2-D) behaviour and three-dimensional (3-D) behaviour. […]

    Scientists have designed a novel photoluminescent material that is cheap to fabricate, does not use toxic starting materials, and is very stable, enhancing our understanding of the quantic nature of photoluminescence. […]

  • How long does a quantum jump take?
    on September 19, 2018 at 5:33 pm

    Quantum jumps are usually regarded to be instantaneous. However, new measurement methods are so precise that it has now become possible to observe such a process and to measure its duration precisely -- for example the famous 'photoelectric effect', first described by Albert Einstein. […]
