A quantum sensing experiment now has the potential to identify single gravitons — the particles that make up gravity — which was considered impossible until now. A team led by Stevens professor Igor Pikovski has recently proposed a method to detect individual gravitons, believed to be the quantum building blocks of gravity. They suggest that with advancements in quantum technology, this experiment could become a reality in the near future.

Following the accelerated expansion discovery of the Universe, scientists introduced dark energy concepts, which faced issues like the cosmological constant problem.

Researchers at IKBFU developed a holographic dark energy model based on quantum gravity, which views the Universe as a hologram. This model, initially unstable, was refined to treat dark energy as perturbations, stabilizing it. It is now being tested against observational data for accuracy.

Put simply, the brain is not too warm or wet for consciousness to exist as a wave that connects with the universe.

For decades, Penrose has been working with anesthesiologist Stuart Hameroff on a theory of consciousness called Orchestrated Objective Reduction (Orch OR). Penrose primarily handles the physics of Orch OR, whereas Hameroff handles the biology. Their theory addressed serious gaps in established scientific frameworks spanning physics, neuroscience and psychology. All, some or none of the hypotheses in this theory might prove out experimentally. See the paper below as a step towards proof.

Entanglement is the essential resource that enables quantum information and processing tasks. Historically, sources of entangled light were developed as experimental tools to test the foundations of quantum mechanics. In this study, we make an extreme version of such a source, where the entangled photons are separated in energy by 5 orders of magnitude, to engineer a quantum interconnect between light and superconducting microwave devices.

Our entanglement source is an integrated chip-scale device with a specially designed acoustic transducer, whose vibrations can simultaneously modulate the frequency of an optical cavity and generate an oscillating voltage in a superconducting electrical resonator. We operate this transducer at cryogenic temperatures to maintain the acoustic and electrical components of the device close to their quantum ground state and excite it with laser pulses to generate entangled pairs. We measure statistical correlations between the optical and microwave emission to verify entanglement.

Our work demonstrates a fundamental prerequisite for a quantum information processing architecture in which room-temperature optical communication links may be used to network superconducting quantum-bit processors in distant cryogenic setups.

A team of engineers and physicists at quantum computing company Quantinuum has conducted the first-ever teleportation of a logical qubit using fault-tolerant methods. In their paper published in the journal Science, the group describes the setup and teleportation methods they used and the fidelity achieved by each.

Decreasing the number of dimensions from three to two to one dramatically influences the physical behaviour of a system, causing different states of matter to emerge. In recent years, physicists have been using optical quantum gases to study this phenomenon.

In the new study, conducted in the framework of the collaborative research centre OSCAR, a team led by Frank Vewinger of the Institute of Applied Physics (IAP) at the University of Bonn looked at how the behaviour of a photon gas changed as it went from being 2D to 1D. The researchers prepared the 2D gas in an optical microcavity, which is a structure in which light is reflected back and forth between two mirrors. The cavity was filled with dye molecules. As the photons repeatedly interact with the dye, they cool down and the gas eventually condenses into an extended quantum state called a Bose–Einstein condensate.

Encoding an image into the quantum correlations of photon pairs makes it invisible to conventional imaging techniques.

Although quantum computing is a nascent field, there are plenty of key moments that defined it over the last few decades as scientists strive to create machines that can solve impossible problems.

Integer quantum Hall effect allows to gauge the resistance standard up to more than one part in a billion. Combining it with the speed of light, one obtains the.
