Quantum Key Distribution Satellite Test

#412

The University of Science and Technology of China (USTC) in Beijing and Stellenbosch University in South Africa have successfully tested a quantum key distribution communication link across 12,900km using the Jinan-1 satellite. The satellite sends encryption keys using quantum entangled photons, which are invalidated if the electrons are observed, if the transmission is intercepted.

Microsoft’s Topological Quantum Chip

#407

Microsoft have developed a topological quantum chip based on Majorana zero modes, which uses braided anyons to implement quantum gates, rather than capturing and observing individual quantum atom states to represent qubits.

Quantum Teleportation In Existing Fibre Optics

#401

Engineers at Northwestern University have demonstrated quantum teleportation of entangled photons using existing internet fibre optic cables, while the cables carried regular internet data traffic. The entangled photons located at either end of the 30 km long fibre optic cable exchanged information without the need for the information to be transmitted the distance of the cable.

Logicial Qubit Error Correction

#391

Microsoft announced a breakthrough in using more logical qubits with error correction in Quantinuum chips, allowing simpler error correction with the added flexibility of moveable ion based hardware qubits. Microsoft also plan to abstract all the error correction layers away from the customer interface layer of their Azure Quantum Cloud service.

Quantum Charging

#309

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.
