The world's biggest gravitational wave observatory is now probing the limits of quantum mechanics.
Quantum microscopes reveal biological structures that would otherwise be impossible to see.
A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.
Researchers have found a way to speed up the search for dark matter using technology from quantum computing. By squeezing quantum noise, detectors can now look for axions twice as fast.
Quantum mechanics is strange. A philosopher explains just how strange, and what it means for reality.
For 60 years, physicists thought they knew exactly how coherent a laser could get. Now the ultimate quantum limit to laser coherence has been found, and it's much much bigger than anybody thought.
We identify an experimental method which could finally reveal whether objects much larger than atoms - such as humans or animals - can exist in several places at once.
A new twist on an old experiment reveals several common-sense ideas about reality can't all be true.
Nobody expected that allowing more communication would make computational problems more reliable.
Physicists can use bright, hot lasers to slow atoms down so much that they measure -459 degrees Fahrenheit.
If every action spilts the universe into different versions, what does that mean for free will?
If it's impossible to accurately predict the future then there may be limits to how smart artificial intelligence can become.
A quantum experiment raises deeply philosophical questions about the fundamental nature of reality.
Manufacturing quantum computers would be a lot easier with existing technology than the exotic components currently used to build them.
Quantum machine learning is an exciting, rapidly growing field.
Heisenberg's famous Uncertainty Principle is put to the test to see if things really are uncertain in the quantum world.
Most people are familiar with lasers. But what about a laser made with sound rather than light? A couple of physicists have now created one that they plan to use for measuring imperceivable forces.
Quantum machine learning is an exciting and rapidly growing field.
Things get weird at the quantum level and now we know they can happen really fast when a particle pushes through an almost insurmountable barrier.
The discovery and development of optical tweezers won the 2018 Nobel Prize in physics. Now physicists are using this tool to crack some of the fundamental questions behind how the universe works.
