If you throw a particle at a wall, there’s a chance that it will suddenly appear on the other side. This is thanks to a phenomenon known as quantum tunneling, and now a team of physicists has measured just how long that process takes.

Quantum entanglement is the idea that two distant atoms can become so entwined that changes to one can instantly affect the other. Now scientists have managed to demonstrate it on a much larger scale, which is beginning to cross over into our everyday world.

Researchers have come up with a way to generate truly random numbers using quantum mechanics. The method uses photons to generate a string of random ones and zeros, and leans on the laws of physics to prove that these strings are truly random, rather than merely posing as random.

When the universe was a few microseconds old, it was a soupy substance called quark-gluon plasma, exhibiting a host of unusual quantum effects previously only thought to occur just after the Big Bang. For the first time, IBM researchers have now observed a gravitational anomaly in earthly materials

If you pushed a ball with negative mass, it would move towards you. It might be hard to picture, but according to Newtonian physics it should be possible. Now a team at Washington State University has demonstrated the phenomenon in practice, creating a fluid that has the properties of negative mass.

According to the experts, quantum cryptography is the most secure way to send data. Based on the laws of physics, any attempt to steal a quantum key not only changes it but also alerts the sender and receiver. So why not use it to make mobile transactions more secure, if not, hack-proof?

Using extremely short, femtosecond pulses of light, engineers are working on ways to so finely control lasers that they can move electrons faster than electric currents – opening the way toward lightwave electronics.

Laser physicists have captured an atomic-level event – an electron being ejected from a helium atom after being struck by a photon – with an accuracy of a trillionth of a billionth of a second, showing the definitive correlation between quantum theory and experimental proof.

The Nobel Prizes are being announced this month, and we now know the winners of the prizes in three fields of science: physics, chemistry and medicine. Here's what you need to know about the advancements in each area that led to the award of some of the world's most prestigious prizes.

We recently reported on a theory that says the Big Bang might have been prevented by the laws of quantum mechanics. As part of our "One Question" series, we asked theoretical physicist Steffen Gielen to help us understand more.
