The race to further understand and eventually harness the potential power of the quantum world is well underway with each year bringing scientists closer to technologies such as quantum computers and quantum encryption. More recently, a group of scientists from the University of Vienna and the Austrian Academy of Sciences, in

Researchers create scalable platform for on-chip quantum emitters
Household lightbulbs give off a chaotic torrent of energy, as trillions of miniscule light particles—called photons—reflect and scatter in all directions. Quantum light sources, on the other hand, are like light guns that fire single photons one by one, each time they are triggered, enabling them to carry hack-proof digital
What Does Quantum Theory Actually Tell Us about Reality?
For a demonstration that overturned the great Isaac Newton’s ideas about the nature of light, it was staggeringly simple. It “may be repeated with great ease, wherever the sun shines,” the English physicist Thomas Young told the members of the Royal Society in London in November 1803, describing what is
7 Quantum Particles Act Like Billions in Weird Physics Experiment
Physicists have revealed that just seven quantum particles can behave as if they were in a crowd of billions. At larger scales, matter goes through changes, called phase transitions, in which (for example) water turns into a solid (ice) or a vapor (steam). Scientists were used to seeing this behavior in large
Researchers ‘teleport’ a quantum gate
Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the "teleportation" of a quantum gate between two qubits, on demand. The findings appear online Sept. 5 in the journal Nature. The key principle behind this new work is quantum teleportation, a unique feature
Quantum computer simulates two types of bizarre materials
Scientists have used a quantum computer to conduct large-scale simulations of two types of quantum materials. These studies involved about 2,000 quantum bits, or qubits — many more than the tens of qubits available in most quantum computers. The results, published in two recent studies in Science and Nature, provide a
