Physicists from the California Institute of Technology partnered with Google Quantum have successfully created a mathematically equivalent holographic quantum wormhole that can teleport a qubit through the wormhole.
Researchers at the Center for Theoretical Physics of Complex Systems within the Institute for Basic Science in South Korea have published research on how to leverage quantum entanglement to speed up the charging time of battery cells, such as those in electric vehicle batteries. Using global operation quantum charging, all cells are charged at the same time, which could slash the charging time of an EV battery to seconds.
Australian quantum computing company Quantum Brilliance released a rack size quantum accelerator that operates at room temperature. The device uses synthetic diamonds as a stable environment for atom based qubits that can maintain coherence for milliseconds at a time. The company plans on miniaturising the accelerator to the size of a graphics card with ~50 qubits.
Quanta Magazine published a nice Quantum Computing expaliner video and article that gives a good overview of the fundametals of quantum computing, and why it is sometimes hard to describe when compared to classical computing.
Researchers have successfully demonstrated quantum entanglement on a cube satellite. A miniture device placed on the SpooQy-1 cubesat demostrated quantum entanglement between pairs of photons within the tiny 20cm x 10cm satellite. This work follows the Chinese Micius satellite which demostrated quantum teleportation over thousands of kilometers.
Physicists have discovered a scenario whereby they can detect an imminent quantum jump in state of a qubit. In the experiment, perfectly timed pulses of radiation can reverse the quantum jump when it is detected, keeping the quibit in its ground state.
