To err is quantum, to correct divine
The next milestone in quantum
computing might not sound as glamorous as ‘quantum supremacy’, but
scientists (and editors) will tell you it’s just as important: error
correction. “It is really the difference between a $100-million,
10,000-qubit quantum computer being a random-noise generator or the most
powerful computer in the world,” says physicist Chad Rigetti, the
co-founder of Rigetti Computing. Discover — with the aid of some helpful graphics — how physicists are trying to keep their qubits queued up.

Ask how artificial intelligence shifts power
When discussing artificial
intelligence (AI), we often ask whether an AI is ‘fair’ and ‘for good’.
But those are infinitely spacious words that any AI system can be
squeezed into, argues AI researcher Pratyusha Kalluri. She suggests asking a deeper question:
how is AI shifting power? “Many researchers think that AI is neutral
and often beneficial, marred only by biased data drawn from an unfair
society,” says Kalluri. “In reality, an indifferent field serves the
powerful.”
