While a quantum computer could factor a 2048-bit RSA key in less than a week with fewer than a million qubits, there are ...

It's a well-known fact that quantum calculations are difficult, but one would think that quantum computers would facilitate the process. In most cases, this is true.

In the fast-evolving world of quantum computing, one of the biggest hurdles isn’t how fast calculations can be done—it’s how long you can hold onto the delicate quantum information in the first place.

Certain quantum phases, such as topological order, are notoriously difficult for computers to identify. The challenge grows with the correlation length, a measure of how far the p ...

Breakthroughs from Google, Caltech, and IBM have reignited debate over “Q-Day,” when quantum computers could break Bitcoin’s cryptography.

Philip Ball dives into the challenges in developing quantum computing, and building up investments and users for the tech ...

Quantum computing could challenge Bitcoin’s cryptography. Here’s how “Q-Day” fears and market psychology may shape the next ...

This image shows 6,100 cesium atoms trapped by highly focused laser beams called optical tweezers. The width of the circle is about one millimeter. Quantum computers will need large numbers of qubits ...

A team of Caltech scientists has fabricated a superconducting qubit on a chip and connected it to a tiny device that scientists call a mechanical oscillator. Essentially a miniature tuning fork, the ...
