Imagine trying to design a key for a lock that is constantly changing its shape. That is the exact challenge we face in ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

When a quantum computer processes data, it must translate it into understandable quantum data. Algorithms that carry out this 'quantum compilation' typically optimize one target at a time. However, a ...

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks. For ...

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

Google claims to have developed a quantum computer algorithm that is 13,000 times faster than the most powerful supercomputers. This would bring the technology another step closer to real-world ...

One of the most well-established and disruptive uses for a future quantum computer is the ability to crack encryption. A new algorithm could significantly lower the barrier to achieving this. Despite ...

Quantum computers won’t break the internet tomorrow… but they will break your email security sooner than you think. Today, cybercriminals and state-sponsored groups are quietly collecting encrypted ...
