Being able to create thousands of photon sources for a truly scalable quantum circuit allows us to create practical, quantum machines that will be solving specialized tasks in the very near future.
Stitch in time: how a quantum physicist made new code from old tricks – University of Sydney
One of the main hurdles for noisy, quantum systems dealing with tiny, fragile parcels of information are the inevitable errors. While eradicating these errors is impossible, Sydney University’s Ben Brown has applied existing 3D error-suppression codes in a 2D architecture, which was also considered impossible. Using these established error-suppression codes frees up a lot of the hardware so it can focus more on solving useful problems, allowing us to produce much more efficient quantum microchips.
While scientists around the world are racing to develop commercial applications for quantum technologies, some companies are jumping the gun.

One of the big hurdles in quantum chemistry is the ability to calculate a molecule’s electronic structure, since you’d have to account for all the potential states that the molecule’s electrons could be in. In a collaboration between the University of Zurich and IBM’s Watson Research Center, researchers have created a machine learning tool that can calculate the energy required to make a molecule. While it can only analyse simpler molecules, it serves as a proof of concept for the vital role of AI and neural networks in solving the mysteries of quantum chemistry.
While scientists often deal with fragile entangled states by freezing them to absolute zero, the Institute of Photonic Sciences has done the opposite by heating them up to 450 Kelvin. By observing the collisions of this mess of atoms, they were able to observe that the atoms remained entangled for 1 millisecond, which means the entangled state can withstand approximately fifty random collisions in that time. While these results are surprising, they hope that this giant entangled state will lead to better sensors for brain imaging, self-driving cars and the search for dark matter.
A path towards quantum computing at room temperature – Tech Explorist
One of the most common barriers to practical, quantum computer circuits is the unnaturally cold temperatures at which they have to operate.

If the US army translates this theoretical success to practical applications, it could spell an enormous shift in international geopolitics.
While many histories of quantum physics have focused on the field’s most foundational theorists, David Kaiser’s new book ‘Quantum Legacies’ takes a different approach. Tracking the changing material conditions of physics, Kaiser documents the rhetorical shifts in the philosophy of physics from the World Wars, through to ‘hippie physics’ in the 60’s and the creation of the Large Hadron Collider. Through this approach, Kaiser bucks the trend of focusing on single geniuses and instead praises the ensemble responsible for quantum physics.
