Sorry, North America. After winning the cosmic lottery with a pair of coast-to-coast total solar eclipses, now it's Europe's turn.
Phys.org / Two-qubit entangling gate flags its own errors as detectable photon losses
Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. ...
Medical Xpress / WHO says Trump vaccine shake-up goes against evidence
The World Health Organization warned Wednesday that Donald Trump's bid to overhaul child vaccination in the United States went against "decades of evidence."
Medical Xpress / Rising temperatures linked to higher risk of homicide and suicide in Mexico and Brazil
