Requires entangled particles, unlike BB84 which does not.

A metric is a function that give the distance, i.e. a real number, between any two elements of a space.

A metric may be induced from a norm as shown at: Section "Metric induced by a norm".

Because a norm can be induced by an inner product, and the inner product given by the matrix representation of a positive definite symmetric bilinear form, in simple cases metrics can also be represented by a matrix.

"Game" is a bit of a stretch as there are no player choices at all.

A more precise word would be simulation.

One of Ciro's most direct experiences with social inequality is described at: São Remo, the favela next to USP.

We have to be careful not to make everyone poorer when trying to reduce inequality.

But as things stand as of 2020, increasing taxes on the very richest, and notably wealth tax, and investing it in free gifted education, seems like a safe bet to achieve any meaningful level of equal opportunity and meritocracy.
