Hawking proposes solution to black hole problem
Light sliding along the boundary of a black hole encodes everything that ever fell inside, suggests Stephen Hawking in a new but incomplete proposal.

Physicists get answers from computer that didn’t run
By exploiting the quirks of quantum mechanics, physicists consistently determined what a quantum computer would have done without actually running the computer.

Quantum communication takes a new twist
A three-kilometer transmission of light above the Vienna skyline demonstrates that scientists can use the twistiness of light to encode delicate quantum information.

Quantum dots get a second chance to shine
Quantum dots, semiconductor particles that can emit a rainbow of colors, have been put to work observing living cells, with possible benefits for medical diagnosis.

Quantum experiment dissects wave-particle mash-up
A modified version of a landmark quantum physics experiment has shown that a single parcel of light can be a particle and a wave simultaneously.

Atomic clock will keep precise time for 15 billion years
The world’s most precise atomic clock will not lose or gain a second in roughly 15 billion years.

One photon wrangles 3,000 atoms into quantum entanglement
A single photon can trigger the creation of quantum entanglement between thousands of atoms.
- Quantum Physics
Quantum links provide clues to causation
Quantum entanglement enables physicists to determine cause and effect just by tracking the association between two measurements.
- Quantum Physics
Finding quantum entanglement in a crowd
Physicists have measured entanglement between pairs of photons within a macroscopic beam of light, a first step toward understanding how particles’ quantum connections lead to large-scale effects.

Light trick can retrieve missed messages
Even if photons pass you by, you can still snatch a signal from their electromagnetic wake, physicists propose.

Trying to get the down-low on gravity
A twist on a classic quantum mechanics experiment could lead to the discovery of elusive gravitons.
