Scientists Create Ultracold Molecules

A team of physicists from MIT has successfully cooled molecules in a gas of sodium potassium (NaK) to a temperature of 500 nanokelvins, creating ultracold molecules. The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each other at speeds of hundreds of miles per hour. Such erratic […]

New Technique Could Make Atomic Clocks More Accurate

Researchers have developed a new technique that can entangle thousands of atoms with a single photon, opening the door to a new class of entangled states. Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in […]

Quantum Experiment Verifies Nonlocal Wavefunction Collapse

Physicists from Griffith University have demonstrated “spooky action at a distance” for the first time with no efficiency loophole by splitting a single photon between two laboratories and experimentally testing if the choice of measurement in one lab really causes a change in the local quantum state in the other lab. An experiment devised in […]

Extending Einstein-Podolsky-Rosen Quantum Mechanics Paradox

Using an optical network, researchers experimentally confirm that entanglement associated with the EPR paradox can be shared over three or more distinct optical systems. An international team, including researchers from Swinburne University of Technology, has demonstrated that the 1935 Einstein-Podolsky-Rosen (EPR) quantum mechanics paradox may be extended to more than two optical systems, paving the […]

Quantum Weirdness Caused by Interacting Parallel Worlds

A new theory of quantum mechanics presumes not only that parallel worlds exist, but also that their mutual interaction is what gives rise to all quantum effects observed in nature. The theory, first published by Professor Bill Poirier four years ago, has recently attracted attention from the foundational physics community, leading to an invited Commentary […]

String Field Theory Linked to Quantum Mechanics

A new study uses string field theory to try to validate quantum mechanics, proposing a link that could open the door to using string field theory — or a broader version of it, called M-theory — as the basis of all physics. “This could solve the mystery of where quantum mechanics comes from,” said Itzhak […]

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 […]

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 […]
