On October 4, 80-year-old John F. Clauser woke up in his California home to find he had received the Nobel Prize in Physics. He will receive the award at a ceremony in Stockholm, Sweden, on December 10 with Anton Zeilinger and Alain Aspect for their work on quantum entanglement. It was a moment of celebration …
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 …

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 …

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 …

Graphic abstract. Credit: Nano-letters (2022). DOI: 10.1021/acs.nanolett.2c03563 A new study involving researchers at the University of Illinois at Chicago has taken an important step in the synthesis of multifunctional photonic nanomaterials. In an article published in the journal Nano-letters, they report the synthesis of “giant” core-shell semiconductor quantum dots with record emissive lifetimes. Additionally, lifetimes …

RE:INVENT “Quantum computing is still in its infancy,” said Simone Severini, director of Quantum Computing at AWS. The Reg. Quantum computers built so far have yet to show any impact on business problems AWS offers a quantum computing service, called Amazon Braket, with a choice of five different brands of hardware, with different ways of …

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 …

We are powerful beyond belief. There is a force of energy that connects us; powerful electromagnetic waves pass through us at all times. Sometimes, if our hearts and minds are aligned, we can catch a riptide carrying us to the edge of human achievement, beyond what we thought possible – an unstoppable force of creation …
For the first time, scientists have created a quantum computing experiment to study the dynamics of wormholes, i.e. shortcuts in spacetime that could circumvent the cosmic speed limits of relativity . Wormholes have traditionally been a part of science fiction, ranging from Jodie Foster’s mad dash to Contact the twists and turns of the plot …

Changing the color of single photons using an integrated phase modulator. Credit: Loncar Lab/Harvard SEAS Optical photons are ideal carriers of quantum information. But to work together in a quantum computer or network, they must have the same color (or frequency) and the same bandwidth. Changing the frequency of a photon requires changing its energy, …
