Cash is expensive in Nigeria. When undercover agents for the Central Bank of Nigeria tried to buy cash on the open market, they found sellers charging markups of 20 percent to 40 percent of face value, the bank governor, Olayemi Cardoso, said at a March event in Abuja.

For decades, researchers have tried to squeeze quantum signals alongside classical signals in fiber optic cables. Quantum bits, however, are based on delicate quantum states of individual particles, which can be disrupted by thermal noise and other factors. Last month, Northwestern University engineers sent a pair of entangled photons more than 30 kilometers through a fiber that was also carrying a 400 gigabits-per-second classical signal.

Nigeria is a leader on e-payments, but a laggard on electricity and Internet penetration, so entrepreneurial Nigerians are bridging the gap with point-of-sale devices: https://t.co/eZtsrytqjq
Félix Martín-Aguilar is looking overseas to expand his start-up. It’s not that he has anything against the Spanish city, his hometown, but Aliqindoi is ready for the big time, he says, and in some ways his choice shows how Málaga is, too. My latest: https://t.co/Vw6CGlghpZ
Large language models, one type of AI, make it easier than ever to search through and generate text. Can they do the same for the inventive ideas that drive science and technology? I visited @IprovaInvents last summer for @IEEESpectrum to find out: https://t.co/bfQqmXyofP
