physicsSometimes Quantum computers do not need to distinguish between cause and effect at all

Researchers have shown that a quantum computer does not need the arrow of time like a classical computer. In some cases, it’s as if the quantum computer doesn’t need to distinguish between cause and effect at all. The new work …

antimatterSolutions for near-term antimatter fusion propulsion using isotope breeding cycle

The world only produces a nanogram of antimatter every year but we cannot store any of it for any length of time. Positron Dynamics has solutions to all of the huge problems to use the immense power of antimatter. Positrons …

energyAGNI Fusion has innovative hybrid ion beam approach to commercial fusion

AGNI wants to achieve a paradigm shift in energy with a nuclear fusion reactor with 10 times the efficiency of fission and no waste. Dr. James Conca covered AGNI for Forbes. AGNI has the ability to remediate all radioactive waste …

photonic computersSingle photon quantum transistor could be the basis for future billion qubit quantum computers

Researchers have demonstrated the first single-photon transistor using a semiconductor chip. The device has numerous holes in it, making it appear much like a honeycomb. Light entering the chip bounces around and gets trapped by the hole pattern. A small …

physicsLarge-Scale Programmable Quantum Simulation using 2048 qubits

A 2048 qubit D-Wave 2000Q™ quantum computer was used to predict phase transitions within a particular quantum mechanical system known as the transverse field Ising model. This work has significantly raised the bar in regards to size and complexity of …

energyColliding powerful electron beams and laser pulses to spark the quantum vacuum and create a lot of antimatter

At intensities around 1024 Watts per square centimeter the field should be strong enough to start to break the mutual attraction between some of the electron-positron pairs. This is basically breaking the quantum vacuum of space. New research proposes the …

molecular nanotechnologyElectron-Beam Manipulation of individual atoms

The scanning tunneling microscope has been able to move atoms over surfaces since the late 1980s. Now, the scanning transmission electron microscope (STEM) is able to reliably focus an electron beam with sub-atomic precision, allowing scientists to directly see each …

diamondSynthetic diamond will enable quantum networks

Princeton University researchers are using synthetic diamonds to help create a quantum communication network. Quantum information networks could be extremely secure and could also allow new quantum computers to work together to solve currently unsolvable problems. The main problem has …

physicsZubrin describes how Dipole Drives can be built and they would be better than other space propulsion

Robert Zubrin has provided more details and analysis of his new dipole drive to Centauri Dreams. The main new information is Zubrin describes the relative simplicity of building simple double sail systems. * dipole drives are buildable to improve cubesat …

lasersDo not hold powerful laser weapons next to your face

China has claimed to have developed a combat laser rifle. It would have to have a lot of waste heat. 30-40% efficiency is about the maximum. China claims a mass produced cost of $15,000. If you had a 300-watt laser …
