IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

If the goal is to make quantum systems act like powerful classical machines, then today’s quantum computers may be too ...

To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university ...

Cleveland Clinic researchers are unlocking quantum computing's full potential through the creation of a new computing paradigm inspired by the human brain. Fabio Cumbo, Ph.D., research associate in ...

The approach is known for high accuracy, but scaling it up while preserving that accuracy is technically difficult. Helios uses barium ions in what is called a quantum charge-coupled device, or QCCD, ...

Bank of America could be setting a new high bar for bullishness when it comes to quantum computing. Analysts at the financial institution, in a recent note to investors, compared the rising technology ...

What if the most complex problems plaguing industries today—curing diseases, optimizing global supply chains, or even securing digital communication—could be solved in a fraction of the time it takes ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

Software firm Horizon Quantum claimed it is the first private company to deploy a commercial quantum computer in Singapore. The deployment also makes it the first quantum software company to deploy ...
