Researchers have created the fastest man-made rotor in the world, which they believe will help them study quantum mechanics.

At more than 60 billion revolutions per minute, this machine is more than 100,000 times faster than a high-speed dental drill.

It turns out that our limited understanding of time is born out of faulty observations and limited perspective. Luckily, quantum computers are on the way.

If our current laws of physics can’t predict what will happen, even probabilistically, we need something new.

The military wants to apply quantum computing to secure communications and inertial navigation in GPS denied environments.

Getting photons to interact is a key step toward using them as qubits.

A team at the University of Science and Technology of China packed three qubits into each of six particles to pull off the unprecedented feat.

A commercially available “quantum computer” has been on the market since 2011, but it’s controversial. The D-Wave machine is nothing like other quantum computers, and until recently, scientists have doubted that it was even truly quantum at all. But the company has released an important new result, one that in part realizes Richard Feynman’s initial dreams for a quantum computer.

Scientists from D-Wave announced they have simulated a large quantum mechanical system with their 2000Q machine—essentially a cube of connected bar magnets. The D-Wave can’t take on the futuristic, mostly non-physics-related goals that many people have for quantum computers, such as finding solutions in medicine, cybersecurity, and artificial intelligence. Nor does it work the same way as the rest of the competition. But it’s now delivering real physics results. It’s simulating a quantum system.

Experiments to confirm we can see single photons offer new ways to probe our understanding of quantum reality.

Electrical engineers at Princeton, working with UK manufacturer Element Six, created synthetic diamonds capable of storing and transmitting quantum information, as published in the journal ‘Science’ on Thursday. The research is a major advance for the creation of quantum-encrypted communications.
