Transporting spatially entangled photons through an optical fiber
Einstein's 'spooky' theory may lead to ultra-secure internet
(Phys.org) —Einstein's scepticism about quantum mechanics may lead to an ultra-secure internet, suggests a new paper by researchers from Swinburne University of Technology and Peking University.
A piece of the quantum puzzle: High level of controllability needed to explore ideas in quantum simulations
While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum ...
Shaking the topological cocktail of success
Graphene is the miracle material of the future. Consisting of a single layer of carbon atoms arranged in a honeycomb lattice, the material is extremely stable, flexible, highly conductive and of particular ...
Physicists find way to boot up quantum computers 72 times faster than previously possible
Press the start button, switch on the monitor, grab a cup of coffee and off you go. That is pretty much how most us experience booting up a computer. But with a quantum computer the situation is very different. ...
All-optical quantum computation, step 1: A controlled-NOT photonic gate
Not all quantum properties are lost through interaction with the environment
'Single-photon emission enhancement' seen as step toward quantum technologies
(Phys.org)—Researchers have demonstrated a new way to enhance the emission of single photons by using "hyperbolic metamaterials," a step toward creating devices in work aimed at developing quantum computers ...
Twisted light waves sent across Vienna
A group of researchers from Austria have sent twisted beams of light across the rooftops of Vienna.
Physicists prove Heisenberg's intuition correct
An international team of scientists has provided proof of a key feature of quantum physics – Heisenberg's error-disturbance relation - more than 80 years after it was first suggested.
Research team challenges the limits of famous quantum principle
(Phys.org) —A team of physicists is challenging the very limits of Heisenberg's famous uncertainty principle by measuring quantum particles with unprecedented accuracy.
New material for quantum computing discovered out of the blue
A common blue pigment used in the £5 note could have an important role to play in the development of a quantum computer, according to a paper published today in the journal Nature.
Team finds elusive quantum transformations near absolute zero
Heat drives classical phase transitions—think solid, liquid, and gas—but much stranger things can happen when the temperature drops. If phase transitions occur at the coldest temperatures imaginable, ...
Quantum theory reveals puzzling pattern in how people respond to some surveys
Researchers used quantum theory – usually invoked to describe the actions of subatomic particles – to identify an unexpected and strange pattern in how people respond to survey questions.
