In a laboratory experiment, researchers from the University of Heidelberg succeeded in realizing an efficient space-time that can be manipulated. In their research on ultracold quantum gases, they were able to simulate a whole family of curved universes to study different cosmological scenarios and compare them to the predictions of a theoretical quantum field model. …

'Quantum time flip' moves light forward and backward in time simultaneously

‘Quantum time flip’ moves light forward and backward in time simultaneously

Leave a Comment / Physics / By

For the first time, physicists have shown that light travels forwards and backwards simultaneously in time. The new technique could help scientists improve quantum computing and understand quantum gravity. By splitting a photon, or a packet of light, using a special optical crystal, two independent teams of physicists have achieved what they describe as a …

Quantum Processor Reveals Photon Bound States Remain Strong Even Amid Chaos

Quantum Processor Reveals Photon Bound States Remain Strong Even Amid Chaos

Leave a Comment / Physics / By

A ring of superconducting qubits can host “bound states” of microwave photons, where photons tend to clump together on neighboring qubit sites. Credit: Google Quantum AI The researchers used a quantum processor to make the microwave photons unusually sticky. They coaxed them into clumping together into bound states, then discovered that these photon clusters survived …

US Department of Energy Breakthrough: Detecting Dark Matter with Quantum Computers

Leave a Comment / Science / By

In a new breakthrough, scientists from the US Department of Energy’s Fermilab have found a way to detect dark matter using quantum computers. Dark matter accounts for about 27% of the universe’s material and energy balance, but scientists don’t know much about it. They know it’s cold, which means the particles that make up dark …

Can quantum computers really create wormholes? | Martin Bauer

Leave a Comment / Physics / By

Recent headlines about physicists creating a wormhole using Google’s quantum computer are misleading. Not only did they not create a wormhole in spacetime, as Einstein’s equations suggest, they didn’t even create a hologram of a wormhole, as claimed. original article from Nature. Martin Bauer explains what the Sycamore experience really was. A “wormhole” is a …

Scientists use quantum computer for teleportation experiment

Leave a Comment / Physics / By

Scientists say they have successfully used a quantum computer to “Teleport” messages between two simulated black holes. Quantum computing uses elements of quantum physics to perform operations too complex for traditional computers. Quantum physics is the study of matter and energy at the level of atoms, or smaller. Researchers recently announced that they created two …
