New method enables quantum simulations on larger systems

Through randomly selected measurements, Austrian physicists can now determine the quantum entanglement of many-particle systems. With the newly developed method, quantum simulations can be extended to a larger number of quantum ...

Can entangled qubits be used to probe black holes? (Update)

Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these ...

Researchers develop new method to reduce quantum noise

In a recent issue of Physical Review A, Argonne researchers reported a new method for alleviating the effects of "noise" in quantum information systems, a challenge scientists around the globe are working to meet in the race ...

Better safeguards for sensitive information

Despite being the most advanced quantum technology, secure encryption of information units based on a method called quantum key distribution (QKD) is currently limited by the channel's capacity to send or share secret bits. ...

Scientists revolutionize cybersecurity through quantum research

Scientists at the RDECOM Research Laboratory, the Army's corporate research laboratory (ARL) have found a novel way to safeguard quantum information during transmission, opening the door for more secure and reliable communication ...

One step closer to complex quantum teleportation

The experimental mastery of complex quantum systems is required for future technologies like quantum computers and quantum encryption. Scientists from the University of Vienna and the Austrian Academy of Sciences have broken ...

Researchers see signs of interactive form of quantum matter

JILA researchers have, for the first time, isolated groups of a few atoms and precisely measured their multi-particle interactions within an atomic clock. The advance will help scientists control interacting quantum matter, ...
