With Q#, Microsoft is throwing programmers the keys to quantum

Posted by in categories: computing, information science, quantum physics

Quantum computers aren’t yet practical, but Microsoft has already developed a programming language for them. Q# works inside Visual Studio, just like most other languages, and could offer aspiring programmers a chance to learn the basics of quantum physics through trial-and-error.

Physicists fight laser chaos with quantum chaos to improve laser performance

Posted by in categories: biotech/medical, quantum physics

To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced another kind of chaos.

High-powered semiconductor lasers are used in materials processing, biomedical imaging and industrial research, but the emitted light they produce is affected by instabilities, making it incoherent.

The instabilities in the laser are caused by optical filaments; light structures that move randomly and change with time, causing chaos. Removing these instabilities has long been a goal in physics, but previous strategies to reduce filaments have usually involved reducing the power of the laser.

Researcher accurately determines energy difference between two quantum states

Posted by in categories: cosmology, particle physics, quantum physics

A kiwi physicist has discovered the energy difference between two quantum states in the helium atom with unprecedented accuracy, a ground-breaking discovery that contributes to our understanding of the universe and space-time and rivals the work of the world’s most expensive physics project, the Large Hadron Collider.

Our understanding of the universe and the forces that govern it relies on the Standard Model of particle physics. This model helps us understand space-time and the fundamental forces that hold everything in the universe in place. It is the most accurate scientific theory known to humankind.

But the Standard Model does not fully explain everything, for example it doesn’t explain gravity, dark matter, dark energy, or the fact that there is way more matter than antimatter in the universe.

Quantum formulation of the Einstein equivalence principle

Posted by in category: quantum physics

The physical conditions that support a geometric interpretation of spacetime, such as the equivalence between rest and inertial mass, are shown not to be necessarily valid in the quantum regime, and a quantum formulation is provided.

Quantum Microscope May Be Able to See Inside Living Cells

Posted by in categories: biotech/medical, quantum physics

By combining quantum mechanical quirks of light with a technique called photonic force microscopy, scientists can now probe detailed structures inside living cells like never before. This ability could bring into focus previously invisible processes and help biologists better understand how cells work.

Photonic force microscopy is similar to atomic force microscopy, where a fine-tipped needle is used to scan the surface of something extremely small such as DNA. Rather than a needle, researchers used extremely tiny fat granules about 300 nanometers in diameter to map out the flow of cytoplasm inside yeast cells with high precision.

To see where these miniscule fat particles were, they shined a laser on them. Here, the researchers had to rely on what’s known as squeezed light. Photons of light are inherently noisy and because of this, a laser beam’s light particles won’t all hit a detector at the same time. There is a slight randomness to their arrival that makes for a fuzzy picture. But squeezed light uses quantum mechanical tricks to reduce this noise and clear up the fuzziness.

Dark Energy May Be Incompatible With String Theory
