Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

We’re nearing the end of the year, and there are typically a flood of announcements regarding quantum computers around now, in part because some companies want to live up to promised schedules. Most ...

Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

Noise is currently quantum computing’s biggest challenge as well as its most significant limitation. IBM is working to reduce that noise in the next few years ...

Protocol corrects virtually all errors in quantum memory, but requires little measure of quantum states. Quantum computers are largely theoretical devices that could perform some computations ...

As with any electronic system, errors in the memory subsystem are possible due to design failures/defects or electrical noise in any one of the components. These errors are classified as either ...

Thomas Stace receives funding from the Australian Research Council through a Future Fellowship and the Centre of Excellence in Engineered Quantum Systems. Computing power has grown exponentially over ...
