Quantum computing is widely believed to be a revolutionary new technology. In fact, it is a double-edged sword. If efficient quantum computers can be manufactured in near future, many of the current ...

Quantum computing in 2026 still isn't a faster laptop. It doesn't make email snappier, and it won't speed up spreadsheets.

For years, quantum computers have been framed as the ultimate problem solvers, machines that would eventually crack any task that classical hardware could not touch. Now a new line of research is ...

In 1994, a mathematician figured out how to make a quantum computer do something that no ordinary classical computer could. The work revealed that, in principle, a machine based on the rules of ...

A team of researchers at the University of Waterloo have made a breakthrough in quantum computing that elegantly bypasses the fundamental "no cloning" problem. The research, "Encrypted Qubits can be ...

Computer scientists’ daydreams have revealed the power of quantum mechanics. Imagine meeting omniscient beings who claim to have the solution to a complex problem that no computer could ever solve.

An important milestone for quantum computers seems to have been reached with Google using a quantum computer to solve a problem 1 billion times faster than the fastest supercomputer in the world. This ...
