The sound of silence? Johns Hopkins researchers show that people feel it

Astonished hearing listening concept

Researchers at Johns Hopkins University have used auditory illusions to examine how moments of silence can distort people’s perception of time, tackling the age-old philosophical question of whether silence can be perceived as more than the absence of sound. A team of psychologists and philosophers at Johns Hopkins University used auditory illusions to show that … Read more

How splitting sound could lead to a new kind of quantum computer

The conversation

When you turn on a lamp to light up a room, you’re experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy. These photons have to obey the sometimes strange laws of quantum mechanics, which, for example, dictate that photons are indivisible, but at the same time allow a photon to … Read more

How split sound could lead to a new kind of quantum computer

A diagram showing a line representing a beam splitter, hitting a phonon.  Two dashed lines on either side of the beam splitter line indicate that the phonon is both reflected from the beam splitter and transmitted to the other side, superimposed.
