Together, they form Helios, a new quantum computer built by the British-American company Quantinuum. Quantum computers use the power of quantum mechanics, the rules that govern how physics operates at ...

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 ...

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

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 ...

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 ...
