New Passive Quantum Error Correction Could Be The Breakthrough for Large Scale Quantum Computers

Researchers led by Prof. David DiVincenzo from Forschungszentrum Jülich and RWTH Aachen University, and partners from the University of Basel and QuTech Delft, have now proposed a design for a quantum computer circuit with passive error correction. Such a circuit would already be inherently fault protected and could significantly accelerate the construction of a quantum …

Path to Megawatt Direct Drive Fusion Propulsion Has No Scientific Roadblocks

A Masters Thesis analyzed a mission to Saturn’s moon Titan using the Princeton Plasma Physics Laboratory Direct Drive Fusion system. The Direct Fusion Drive (DFD) is based on a D-3He fueled, aneutronic, thermonuclear fusion propulsion system. He considered a 2-MW-class single DFD module, which provides 8 N of constant thrust and a specific impulse of …

Record Time Measurement is Time for Light to Cross a Hydrogen Molecule

There is a breakthrough in experiments studying ultrafast processes. One of the most fundamental processes caused by the light-matter interaction where a light photon causes the ejection of an electron and the formation of anion. Using an electron interferometric technique researchers report a birth time delay on the order of a few hundred zeptoseconds (247 …

Room Temperature Superconductor Under Diamond Anvil Pressures

University of Rochester researchers squeezed carbonaceous sulfur hydride in a diamond anvil and it superconducted at 15 degrees Celsius under 270 gigapascals of pressure. This is about 2.5 million times regular atmospheric pressure. The bottom of the Mariana Trench has 1071 times the pressure of regular atmosphere. The sample were between 25 and 35 microns. …

High-Temperature Superconductor Cable Will Speed Up Development of Nuclear Fusion

Commonwealth Fusion Systems new high-temperature superconductor (HTS) cable can be engineered into magnets directly applicable to the high magnetic field approach to fusion. The new HTS cable, called VIPER, can carry over fifty thousand amps of current with magnetic fields over 10 Tesla. Some fusion magnets need to turn on and off continually. VIPER was …

Roger Penrose Shares Nobel Prize in Physics and Pushes His Cyclic Universes Theory

Roger Penrose has shared in the Nobel Prize in Physics for his contribution with models of Black Holes. Penrose has used the renewed attention to push his 30-year old concept of Hawking Points and cyclic universes. This theory challenges the theory of cosmic inflation. Above – CMB sky, marking 6 most prominent raised-temperature circular spots, …

Entanglement Between Distant Macroscopic Objects Could Improve LIGO Gravity Measurements

Researchers have demonstrated entanglement between distant objects (millimeters in size and with billions atoms in a magnetic field) in a hybrid system consisting of a mechanical oscillator and an atomic spin ensemble. This constitutes a new milestone for hybrid macroscopic entanglement and for demonstration of noiseless trajectories in the negative-mass reference frame. Future applications of …
