Quantum Navigation Space Test

The US Military will be testing a quantum inertial sensor on board an upcoming X037B spaceflight. The quantum navigation device users atom interferometry to supercool atoms and measure overlapping waves patterns of the atoms, which represent positional shifts. The method produces accurate dead-reckoning without any drift or need for external references.

Quantum Consciousness

#416

Nirvanic are developing a quantum consciousness test platform to test theories on the possibility of quantum mechanics being responsible for consciousness. The test setup takes input from a webcam attached to a robot, sends the data to a D-wave quantum computer, which then returns a desired action for the robot to take. The idea is to compare the quantum powered setup with a classical system to see if there are any differences in the actions returned from the camera input.

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.
