Beam me up! Teleporting the memory of an organism

Physicists propose the first scheme to teleport the memory of an organism
Physicists propose the first scheme to teleport the memory of an organism

LLAP, Leonard Nimoy

In “Star Trek”, a transporter can teleport a person from one location to a remote location without actually making the journey along the way. Such a transporter has fascinated many people. Quantum teleportation shares several features of the transporter and is one of the most important protocols in quantum information.

Physicists show ‘molecules’ made of light may be possible

Physicists show 'molecules' made of light may be possible

It’s not lightsaber time… at least not yet. But a team including theoretical physicists from the National Institute of Standards and Technology (NIST) has taken another step toward building objects out of photons, and the findings* hint that weightless particles of light can be joined into a sort of “molecule” with its own peculiar force.

Cell phone notifications may be driving you to distraction

Cell phone notifications may be driving you to distraction

Whether you are alerted to an incoming phone call or text by a trendy ringtone, an alarm bell or a quiet vibration, just receiving a notification on your cell phone can cause enough of a distraction to impair your ability to focus on a given task.┬áIn fact, the distraction caused by a simple notification — whether it is a sound or a vibration — is comparable to the effects seen when users actively use their cell phones to make calls or send text messages, the researchers found.

Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place. A team of scientists at the Vienna University of Technology has now demonstrated that this problem can be solved – not only in strange, unusual quantum systems, but in the glass fiber networks we are already using today.
