A device with more than 6000 quantum bits, or qubits, has smashed a previously-held record and is the first step towards building the largest quantum computer yet. Each of these is a neutral caesium ...

The promise of quantum computing has been building up year after year, and yet still seems as far away from practical reality as it has ever been. The good news is that there are finally end goals in ...

Together, they form Helios, a new quantum computer built by the British-American company Quantinuum. Quantum computers use ...

A programmable photonic circuit has been developed that can execute various quantum algorithms and is potentially highly scalable. This device could pave the way for large-scale quantum computers ...

A new Quantum Monte Carlo algorithm in Physical Review Letters marks a significant step forward in the quest to build ...

A familiar thought experiment about a hidden cat has helped scientists take a meaningful step toward building reliable ...

Jacob Benestad in front of an experimental setup in the laboratory at the Niels Bohr Institute, University of Copenhagen. This setup is similar to the one used during the group's experiments at the ...
