A University of Oklahoma astrophysics team has discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing–an astronomical phenomenon and the only known method capable of discovering planets at truly great distances from the …

futureQuantum hack allows quantum computing systems to tolerate 400% gain in interference

No Comments
Modifying surface codes can improve quantum error correction 400 percent. The instability of qubits – the building blocks of quantum computers – means they are susceptible to error. Physicists have found that tweaking error coding can open the door to …
