Scientists Propose Existence of Parallel Worlds

In a newly published study, physicists propose that parallel universes really exist and that they interact and influence one another by a subtle force of repulsion. Griffith University academics are challenging the foundations of quantum science with a radical new theory based on the existence of, and interactions between, parallel universes. In a paper published […]

New Research Suggests Electron Wave Function Can Be Separated into Many Parts

A newly published study from Brown University suggests that the quantum state of an electron — the electron’s wave function — can be shattered into pieces and trapped. Providence, Rhode Island (Brown University) — New research by physicists from Brown University puts the profound strangeness of quantum mechanics in a nutshell — or, more accurately, […]

Yale Engineers Develop a Chip Scale Device That Uses Interaction Free Measurement

Engineers at the Yale School of Engineering & Applied Science have developed a chip-scale device that uses the wave-particle duality of single photons to sense the presence of an object without interacting with it – a technique known as “interaction-free measurement.” “Our device uses silicon photonics to create interaction-free measurement on an integrated chip—something previously […]

Researchers Develop a Way to Probe the Kind of Matter that Dominated the Universe Immediately After the Big Bang

Nuclear scientists at the U.S. Department of Energy’s Lawrence Berkeley National Lab have made the most precise extraction to date of a key property of the quark-gluon plasma, which reveals the microscopic structure of this almost perfect liquid. By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property […]

Physicists Chilled Molecules to Very Near to Absolute Zero

Using magneto-optical trapping, Yale physicists cooled molecules of strontium monofluoride to 2.5 thousandths of a degree above absolute zero, the lowest temperature yet achieved by direct cooling of a molecule. It’s official. Yale physicists have chilled the world’s coolest molecules. The tiny titans in question are bits of strontium monofluoride, dropped to 2.5 thousandths of […]

A New Discovery of Quantum Critical Points

Physicists have discovered new “quantum critical points” in a class of iron superconductors known as “oxypnictides,” furthering their understanding of quantum criticality. Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study. But a new discovery of “quantum critical points” could allow physicists to develop a […]

Researchers Observe What Happens During a Quantum Phase Transition

In a newly published study, researchers observe what happens during a quantum phase transition, and compare the “quantum melting” of the magnetic structure with the classical “thermal melting” phase transition. When ice is warmed, the water molecules forming its structure vibrate more and more vigorously until finally the forces between them are no longer strong […]

Researchers Entangled Two Independent Photons with Different Frequencies for the First Time

Using time-resolved measurement and active feed forward, researchers from the University of Science and Technology of China have entangled two independent photons of different colors for the first time. Entanglement has been capturing the imagination of scientists as well as the public ever since it first emerged from the newly minted quantum mechanics formalism eight […]

Quantum Mechanics May Lead to Ultra Secure Internet

Researchers give theoretical proof that quantum mechanics may lead to an ultra-secure internet. Einstein’s skepticism about quantum mechanics may lead to an ultra-secure internet suggests a new paper by researchers from Swinburne University of Technology and Peking University. Associate Professor Margaret Reid from Swinburne’s Center for Quantum and Optical Science said Einstein’s reservations about quantum […]

Researchers Find Direct Evidence of Cosmic Inflation

Researchers have discovered the first direct evidence of cosmic inflation, confirming a deep connection between quantum mechanics and general relativity. Cambridge, Massachusetts – Almost 14 billion years ago, the universe we inhabit burst into existence in an extraordinary event that initiated the Big Bang. In the first fleeting fraction of a second, the universe expanded […]

Photon Glue Enables a New Quantum Mechanical State

A team of researchers has taken the excited states of two principally different materials and combined them into a new quantum mechanical state that shares their best properties. Ann Arbor — Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials. […]
