How suspicions of spying threaten cross-border science – Technology Review
A report from Strider, an American intelligence startup, accuses China of using European and American funding to develop military applications for quantum technology. The report was dismissed by scientists, warning against creating an unnecessarily hostile environment and jeopardizing hard-earned international scientific relationships. While Strider admitted that there is no direct evidence linking these researchers and the chinese military, the report’s existence highlights the growing anxiety and tension between science and security.
A group of MIT researchers have created an AI model that understands physics as well as a three-month-old baby. By studying infants after presenting them with physical objects, the researchers created a schema that teaches machines everything from object solidity and permanence to motion.

The quantum dot is one of the rare offshoots of quantum mechanics that has been commercially available for consumers for some years now. Colloidal Quantum Dots (CQD’s) are semiconductor nanoparticles that are used in the display screens of many electronic devices, due to their ability to generate vivid colours when powered by another source of light energy. This week, a team from Nanyang Technological University have managed to couple CQD’s with electric fields to emit laser light using only a fraction of the energy required for traditional lasers. If this cheap, already-commercially available quantum technology can be used for laser light, it could revolutionise the laser-reliant fields of medicine, security and consumer electronics.
Superconductors are able to conduct electricity without resistance, but are generally only operational at abnormally low temperatures. However, some iron-based superconductors operate at room-temperature, and an international team of researchers are close to figuring out why. By adding cobalt atoms to an iron superconductor, they were able to make superconductivity disappear, which demonstrates a quantum phase transition and brings us closer to developing an accessible version of an otherwise exotic superconductor.
Quantum computers could mark their own homework – Physics World
Due to their sensitivity to environmental noise, quantum computers are often error prone. This week, scientists from the UK’s University of Warwick have created an efficient protocol for assessing the correctness of quantum computing. Previously, conventional computers were used to check the correctness of quantum calculations, but this method should be abandoned eventually if quantum computers are to outperform than conventional computers. The team’s protocol is done entirely by quantum computers and would hopefully jettison our counterproductive reliance on conventional computers.

When two photons are entangled, the quantum state of the first will correlate with the state of the second, regardless of how close they are to each other. This week, researchers from Switzerland and Iran have opened up quantum theory by asking what would happen when three pairs of entangled photons are placed in a network. When they forced two photons from separate pairs to become entangled, the connection was also present in their twin photon elsewhere in the network. This important theoretical discovery underlines the power of quantum correlations in networks, which far exceeds what researchers had originally thought possible.
Quantum vacuum: Less than zero energy – Phys.org
Classical physics would posit that there is a natural bottom-limit to energy; once every single particle is removed from a certain volume and there is nothing left to carry energy, that is where energy ends. An international research team from Austria, Belgium and India have proven that under certain conditions, negative energies are temporarily allowed. When thought in terms of the theory of general relativity, negative energy means we could expect negative mass and negative gravity.
