For the first time, a quantum computer has solved a task that Google says would be impossible for the most advanced supercomputers in the world.
Unlike traditional computers that rely on bits of information that can be in one of two states (1 or 0), quantum computers manipulate qubits, or units of information tucked inside subatomic particles. That means, they follow the wacky laws of quantum mechanics and so can be in two states at once. This ability allows quantum computers to theoretically store exponentially more information than your everyday laptop. Live Science is here to dissect the latest achievements and discoveries in this bizarre quantum world of computing.
From ancient Greece to the age of quantum computers, cryptography continues to keep our secrets safe.
A new technique for quantum computing could bust open our whole model of how time moves in the universe.
In an unprecedented feat, physicists packed three qubits into each of six particles. The implications could be staggering.
Pulses of light from infrared lasers can speed up computer operations by a factor of 1 million, and may have opened the door to room-temperature quantum computing.
The Chinese satellite Micius has once again shattered records, this time enabling practical quantum encryption between Beijing and Austria.
The year 2017 was weird all over. And what science is better-suited for a weird year than quantum physics?
A quantum-encrypted message containing more than one bit of information in each particle of light was beamed through the air between two buildings in a real-life city for the first time.
Scientists have proposed a new way to build a quantum computer using microwaves to control individual atoms, and they say the new method offers a blueprint for a more useful computing machine.
Diamonds may decorate some of the most coveted pieces of bling, but these precious stones could one day have a more practical use: storing vast amounts of data.
Researchers have now performed "quantum teleportation" of laser pulses over several miles within two city networks of fiber optics.
