The achievement in silicon, the basis of the computer chip, has important implications for integration with existing technology, according to a team from Britain, Japan, Canada and Germany whose study was published in the journal Nature on Wednesday.
"Creating 10 billion entangled pairs in silicon with high fidelity is an important step forward for us," said John Morton of Britain's Oxford University, who led the team.

"We now need to deal with the challenge of coupling these pairs together to build a scalable quantum computer in silicon."
Scientists believe that super-fast quantum computers, based on quantum bits, or qubits, will be able to test many possible solutions to a problem at once.
Conventional computers based on binary "switches," or bits, can only do one thing at a time.
Quantum entanglement involves the notion that particles can be connected in such a way that changing the state of one instantly affects the other, even when they are miles apart.
Albert Einstein once famously described it as "spooky action at a distance."
Other areas of quantum-related research include ultra-precise measurement and improved imaging.
