First Light Fusion Generates Neutrons

First Light used a large two-stage hyper-velocity gas gun to launch a projectile at a target, containing the fusion fuel and achieved fusion. The projectile reached a speed of 6.5 km per second before impact. First Light’s highly sophisticated target focuses this impact, with the fuel accelerated to over 70 km per second (151,000 mph) …

New Class of Superconductor

(Ba,K)BiO3 constitute an interesting class of superconductors, where the remarkably high superconducting transition temperature Tc of 30 K arises in proximity to charge density wave order. However, the precise mechanism behind these phases remains unclear. Here, enabled by high-pressure synthesis, we report superconductivity in (Ba,K)SbO3 with a positive oxygen–metal charge transfer energy in contrast to (Ba,K)BiO3. …

Cryospheric Quantum Rydberg Radar

Another NASA advanced concpet project is Cryospheric Quantum Rydberg Radar. This is especially interesting to Nextbigfuture because this overlaps with ColdQuanta’s QuantumRF work. Nextbigfuture interviewed ColdQuanta VP Max Perez about Atomic clocks and QuantumRF and Quantum computers. ColdQuanta has close to $100 million in funding and grants. ColdQuanta is doing advanced work with laser arrays …

Possible Room Temperature Superconductor Under Diamond Anvil Pressure

Superconductivity in a photochemically transformed carbonaceous sulfur hydride system, starting from elemental precursors, with a maximum superconducting transition temperature of 287.7 ± 1.2 kelvin (about 15 degrees Celsius) achieved at 267 ± 10 gigapascals. The superconducting state is observed over a broad pressure range in the diamond anvil cell, from 140 to 275 gigapascals, with …

ColdQuanta Atom Tech for Million Qubit Quantum Computers and Beyond

ColdQuanta cools atoms to a few millionths of a degree above absolute zero and uses lasers to arrange the atoms, hold them in place, run computations on them, and read out the results. Quantum calculations, communications, and sensing are the result. Satyendra Bose and Albert Einstein discovered the fifth form of matter—the Bose-Einstein Condensate (BEC). …

DARPA Wants to Create Portable Atomic Clocks

Global Positioning Systems (GPS) are vital for the military for precision warfare but GPS can be jammed by military opponents. DARPA has announced the Robust Optical Clock Network (ROCkN) program, which aims to create optical atomic clocks with low size, weight, and power (SWaP) that yield timing accuracy and holdover better than GPS atomic clocks …

Superabsorption Progress Towards Quantum Batteries

University of Adelaide and their overseas partners have successfully proved the concept of superabsorption, a crucial idea underpinning quantum batteries. Quantum batteries offer the potential for vastly better thermodynamic efficiency, and ultra-fast charging time, much faster and more efficient than the electrochemical batteries like Nickel Metal Hydride or Lithium Ion, in common use today. By …

Metalenses Sorts Color Without Color Filters

Polarization-insensitive metasurface lenses (metalenses) sort primary colors on high-density pixels without the use of color filters. The metalenses simultaneously act as pixel-scale color splitters and lenses and are compatible with complementary metal–oxide-semiconductor sensor technology. An image sensor with such metalenses significantly enhances the detected light power, while affording high image quality, incident angle tolerance, and …

Quantum Spin Liquid Could Enable Topological Qubits

A new state of matter, called quantum spin liquid, produces long-range quantum entanglement which might help make quantum computers. They could enable topological qubits. Bill Gates and Microsoft have been funding efforts to create a topological quantum computer. Topological qubits could theoretically be far more stable and enable long lasting quantum calculations. The work is …
