Dense ensembles of laser-cooled molecules allow the observation of molecular collisions—a result that could lead to applications of cold molecular gases in quantum simulation and fundamental physics tests.

Quantum physics requires high-precision sensing techniques to delve deeper into the microscopic properties of materials. From the analog quantum processors that have emerged recently, quantum-gas microscopes have proven to be powerful tools for understanding quantum systems at the atomic level. These devices produce images of quantum gases with very high resolution: They allow individual atoms to be detected.

Researchers simulated a key quantum state at one of the largest scales reported, with support from the Quantum Computing User Program, or QCUP, at the Department of Energy’s Oak Ridge National Laboratory.
In the 1920s, Erwin Schrödinger wrote an equation that predicts how particles-turned-waves should behave. Now, researchers are perfectly recreating those predictions in the lab.
Quantum dots are already moving in the premium display category, particularly through QD-OLED TVs and monitors. The next step could be QDEL, short for “quantum dot electroluminescent,” also known as NanoLED, screens. Not to be confused with the QLED (quantum light emitting diode) tech already available in TVs, QDEL displays don’t have a backlight. Instead, the quantum dots are the light source. The expected result is displays with wider color spaces than today’s QD-OLEDs (quantum dot OLEDs) that are also brighter, more affordable, and resistant to burn-in.
It seems like QDEL is being eyed as one of the most potentially influential developments for consumer displays over the next two years.
If you’re into high-end display tech, QDEL should be on your radar.
NVIDIA is all set to aid Japan in building the nation’s hybrid quantum supercomputer, fueled by the immense power of its HPC & AI GPUs.
Japan To Rapidly Progressing In Quantum and AI Computing Segments Through Large-Scale Developments With The Help of NVIDIA’s AI & HPC Infrastructure
Nikkei Asia reports that the National Institute of Advanced Industrial and Technology (AIST), Japan, is building a quantum supercomputer to excel in this particular segment for prospects. The new project is called ABCI-Q & will be entirely powered by NVIDIA’s accelerated & quantum computing platforms, hinting towards high-performance and efficiency results out of the system. The Japanese supercomputer will be built in collaboration with Fujitsu as well.
An Ongoing Meta-analysis of Gravitational Wave Signals may soon Prove that Space Remembers: permanent memory imprints in spacetime may soon be detected, which will be a validation of Nassim Haramein and our research team’s prediction that space has the property of memory, in which we described how the informational imprint of memory in space is what holographically generates time—that is to say that 4D spacetime is a hologram of a 3D voxel information network—as well as ordering properties underlying dynamics of organized matter. The gravitational wave memory effect is a prediction of general relativity, and physicists have devised a test of this interesting spacememory effect via a meta-analysis of gravitational wave detector data. The presence of memory effects in gravitational wave signals not only provides the chance to test an important aspect of general relativity, but also represents a potentially non-negligible contribution to the waveform for certain gravitational wave events. As well, memory properties of space will have far-reaching implications, from probing theories of quantum gravity and unified physics to potential applications in telecommunications technologies.
In a study recently published in Nature, researchers from the Max Born Institute in Berlin, Germany, and the Max-Planck Institute of Quantum Optics in Garching have unveiled a new technique for deciphering the properties of matter with light, that can simultaneously detect and precisely quantify many substances with a high chemical selectivity.
Their technique interrogates the atoms and molecules in the ultraviolet spectral region at very feeble light levels. Using two optical frequency combs and a photon counter, the experiments open up exciting prospects for conducting dual-comb spectroscopy in low-light conditions and they pave the way for novel applications of photon-level diagnostics, such as precision spectroscopy of single atoms or molecules for fundamental tests of physics and ultraviolet photochemistry in the Earth’s atmosphere or from space telescopes.
Researchers have produced, stored, and retrieved quantum information for the first time, a critical step in quantum networking.
The ability to share quantum information is crucial for developing quantum networks for distributed computing and secure communication. Quantum computing will be useful for solving some important types of problems, such as optimizing financial risk, decrypting data, designing molecules, and studying the properties of materials.
“Interfacing two key devices together is a crucial step forward in allowing quantum networking, and we are really excited to be the first team to have been able to demonstrate this.” —
