New design surpasses the coherent interaction limit
Coherent light-matter interaction at the single photon level is a long-standing goal for quantum operations. To reach such strong coupling regime, previous studies mainly focus on improving the quality (Q) ...
Electrical control of nuclear spin qubits
Researchers of Karlsruhe Institute of Technology (KIT) and their French partners succeeded in making an important step towards quantum computers. Using a spin cascade in single-molecule magnet, the scientists ...
Quantum criticality observed in new class of materials
(Phys.org) —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 ...
Shaken, not stirred: Control over complex systems consisting of many quantum particles
At TU Vienna, a new method was developed to utilize quantum mechanical vibrations for high precision measurements. The well-known concept of the Ramsey interferometer is applied to a complex multi particle ...
Researchers confirm 60-year-old prediction of atomic behavior
Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
Physicists take quantum leap toward ultra-precise measurement
For the first time, physicists at the University of Toronto (U of T) have overcome a major challenge in the science of measurement using quantum mechanics. Their work paves the way for great advances in using ...
Space-based experiment could test gravity's effects on quantum entanglement
Research team claims to have accurately 'teleported' quantum information ten feet
A matter of matter: Demonstrating destructive quantum interference using Bose-Einstein condensates
Heads or tails: Experimental quantum coin flipping cryptography performs better than classical protocols
The quest for true randomness and uncrackable codes
Quantum cryptography is said to be uncrackable. It will stay safe, but only if true randomness, the generation and use of intrinsically random numbers, can be achieved.
New analysis eliminates a potential speed bump in quantum computing
A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
Fast and curious: Electrons hurtle into the interior of a new class of quantum materials
As smartphones get smarter and computers compute faster, researchers actively search for ways to speed up the processing of information. Now, scientists at Princeton University have made a step forward in ...
Researchers find nondestructive method to study quantum wave systems
The laws of classical physics that describe the world around us can be very different from those of the quantum world. At the quantum level, particles can behave more like waves that can pass through each ...
