Is there a prominent Brexiter left who hasn’t torn off their mask to reveal the rancid racism beneath? Boris Johnson’s chief fluffer accusing anyone else of being over-promoted is peak process. The bitterness of insanely privileged men with empty souls knows no bounds.
For anyone still tempted to take Dominic Cummings at all seriously, he's now an advocate of Donald Trump-style open racism.

Quantum networks might one day enable more secure options for communication and distributed computation and are therefore currently a hot research topic, one which presents many challenges: One is the on-demand distribution of quantum systems that feature genuine multipartite entanglement (GME). 1/8

The govt published its strategy to revitalise local communities last week
There is a heavy focus on directing funding to high streets and community spaces, which is part of the reason for declining "pride in place"
But it seems misguided for a few reasons

🔍 How uncertain can quantum systems be?
Saulo Moreira shares work developing new bounds that show how quantum effects—like coherence and correlations—can break classical limits on uncertainty.
This helps us better understand how quantum systems behave when measured.
