Coupling qubits to sound in a multimode cavity

In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or number states) are quantum states ...

It's a one-way street for sound waves in this new technology

Imagine being able to hear people whispering in the next room, while the raucous party in your own room is inaudible to the whisperers. Yale researchers have found a way to do just that—make sound flow in one direction—within ...

Assembly in the air: Using sound to defy gravity

Scientists at the University of Bath have levitated particles using sound in an experiment which could have applications in so-called "soft robotics" and help reveal how planets start to form.

Mechanism helps explain the ear's exquisite sensitivity

The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered ...

Quantum sound waves to open doors for more powerful sensors

For the last decade, scientists have been making giant leaps in their ability to build and control systems based on the bizarre rules of quantum mechanics, which describe the behavior of particles at the subatomic scale.

Sound waves reveal diamond cache deep in Earth's interior

There may be more than a quadrillion tons of diamond hidden in the Earth's interior, according to a new study from MIT and other universities. But the new results are unlikely to set off a diamond rush. The scientists estimate ...

New laser makes silicon 'sing'

Yale scientists have created a new type of silicon laser that uses sounds waves to amplify light. A study about the discovery appears June 8 in the online edition of the journal Science.

Longitudinal wave

Longitudinal waves are waves that have same direction of oscillations or vibrations along or parallel to their direction of travel, which means that the oscillations of the medium (particle) is in the same direction or opposite direction as the motion of the wave. Mechanical longitudinal waves have been also referred to as compressional waves or compression waves.
