"…we usually think of temperature as something that destroys #quantumeffects," adds Thomas Agrenius, who helped develop the theoretical understanding of the experiment. "Our measurements confirm that quantum interference can persist even at high temperatures."

Hot Schrödinger cat states created

Quantum states can only be prepared and observed under highly controlled conditions. A research team from Innsbruck, Austria, has now succeeded in creating so-called hot Schrödinger cat states in a superconducting microwave resonator. The study, published in Science Advances, shows that quantum phenomena can also be observed and used in less perfect, warmer conditions.

Quantum effects forbid the formation of black holes from high concentrations of intense light, say physicists

For the last seven decades, astrophysicists have theorized the existence of "kugelblitze," black holes caused by extremely high concentrations of light.

It looks like #MooresLaw still has a long future. A recent paper describing a #graphene based, 5-lane "superhighway" was recently proven out at -456 ℉. High-efficiency, room-temperature #superconductivity was already possible possible in other ways at 59-68 ℉. The discovery of #RhombohedralGraphene could lead to significant improvements in bandwidth for low-power computing.

Graphene-based materials have #quantumeffects on electrons. I'd be very surprised if there weren't also implications here for #quantumcomputing. We're living in the future, folks!

  • Physicists create five-lane superhighway for electrons

    MIT physicists and colleagues have created a five-lane superhighway for electrons that could allow ultra-efficient electronics and more. The work, reported in the May 9 issue of Science, is one of several important discoveries by the same team over the last year involving a material that is essentially a unique form of pencil lead.

    Quantum effects detected in hydrogen and noble gas collisions

    A Freie Universität Berlin research team headed by quantum physicist Professor Christiane Koch has demonstrated how hydrogen molecules behave when they collide with noble gas atoms such as helium or neon. In an article published in the journal Science, the researchers describe how they used simulations to draw connections between data from experiments and theoretical models of quantum physics.
