Quantum computers are all over the news, but what are they

and how do they differ from conventional computing?

Advanced passive voice

If they can be built economically and at scale

quantum computers will harness properties

that extend beyond the limits of classical physics

to offer us exponential gains in computing power.

Classical computers are made of bits, a unit of information

But in a quantum computer, the basic unit, known as a qubit,

can represent both 0 and 1 at the same time, a state known

rises exponentially, enabling it to compute

millions of possibilities instantaneously.

could revolutionise fields from cryptography to chemistry,

ranging from materials science, agriculture,

and pharmaceuticals, not to mention artificial intelligence

So far, the challenge has been to scale up

the number of qubits to perform useful calculations

This week Google has published a landmark paper

can perform a very specific calculation in 200 seconds that

would take today's most powerful computer 10,000

This demonstration is known as quantum supremacy.

This is just the first step towards creating

Next, scientists will have to build a scaled-up version that

can perform real world, useful calculations, thus achieving
