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.
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.
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.
China launched the first-ever quantum satellite Monday (Aug. 15), in an effort to help develop an unhackable communications system.
The technology could usher in a much-anticipated era of quantum computing, which researchers say could help scientists run complex simulations and produce rapid solutions to tricky calculations.
Scientists have for the first time made an advanced machine known as a quantum computer simulate ghostly particles that fluctuate in and out of existence.
The Schrodinger's Cat thought experiment is even weirder than people thought, with the quantum cat trapped in a box able to be alive and dead in two places at once.
Scientists have devised a way to get quantum information from a black hole, but the amount of information they can get is limited.
The one thing everyone knows about quantum mechanics is its legendary weirdness, in which the basic tenets of the world it describes seem alien to the world we live in.
The prototype of the memcomputer, which works by mimicking the human brain, could one day lead to computers that solve notoriously difficult math problems and could even help to break codes.
Building a quantum computer can sometimes yield unexpected benefits — like providing the right environment to demonstrate that Albert Einstein's theory of special relativity is, in fact, correct.
A new particle detector has made it possible to generate three entangled photons that could be used in quantum telecommunication.
Researchers developed a technique to calculate quantum wave functions 350 times faster than previous methods.
