Experimental method measures quantum coherence, the ability of being in two states at once

Researchers have come up with a method that allows measuring the strength of the coherence of superposition in any given quantum state, similar to the famous Schrödinger’s cat, which described as being simultaneously dead and alive. The method is based on the measurement of experimental parameters related to the visibility of the interference fringes pattern produced when the two states are superimposed. […] Read More

Ultracold molecules hold promise for quantum computing

Researchers have taken an important step toward the long-sought goal of a quantum computer, which in theory should be capable of vastly faster computations than conventional computers, for certain kinds of problems. The new work shows that collections of ultracold molecules can retain the information stored in them, for hundreds of times longer than researchers have previously achieved in these materials. […] Read More

Ultracold molecules hold promise for quantum computing

A study by MIT researchers shows that collections of ultracold molecules can retain the information stored in them for hundreds of times longer than previously achieved in these materials. These clusters might thus serve as ‘qubits,’ the basic building blocks of quantum computers. […] Read More

New magnet has nearly massless charge carriers

Advances in modern electronics has demanded the requisite hardware, transistors, to be smaller in each new iteration. Recent progress in nanotechnology has reduced the size of silicon transistors down to the order of 10 nanometers. However, for such small transistors, other physical effects set in, which limit their functionality. The recent discoveries of topological materials — a new class of relativistic quantum materials — hold great promise for use in…

Scientists watch ‘artificial atoms’ assemble into perfect lattices with many uses

Some of the world’s tiniest crystals are known as ‘artificial atoms’ because they can organize themselves into structures that look like molecules, including ‘superlattices’ that are potential building blocks for novel materials. Now scientists have made the first observation of these nanocrystals rapidly forming superlattices while they are themselves still growing. […] Read More

Single-photon emitter has promise for quantum info-processing

Los Alamos National Laboratory has produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths. These carbon nanotube quantum light emitters may be important for optically-based quantum information processing and information security, while also being of significant interest for ultrasensitive sensing, metrology and imaging needs and as photon sources for fundamental advances in quantum optics studies. The research was reported today in the journal…

Detecting radio waves with entangled atoms

In a study published in Physics Review Letters and highlighted by APS Physics, ICFO researchers demonstrate a new technique for the coherent detection of radio frequency magnetic fields using an atomic magnetometer. They used highly sensitive, nondestructive measurements to entangle the atoms while maintaining their collective coherence, and a new technique to allow the coherent buildup of signal from arbitrarily shaped waveforms.

Improving understanding of the quantum world with quantum dots

Quantum behavior plays a crucial role in novel and emergent material properties, such as superconductivity and magnetism. Unfortunately, it is still impossible to calculate the underlying quantum behavior, let alone fully understand it. Scientists of QuTech, the Kavli Institute of Nanoscience in Delft and TNO, in collaboration with ETH Zurich and the University of Maryland, have now succeeded in building an “artificial material” that mimics this type of quantum behavior…
