To do this you would need to build a quantum computer with a few so-called “logical” qubits that actually do the math, and a bunch of standard qubits that correct for errors.

We've all read plenty about quantum computing, and its promise for computing breakthroughs. But it isn't easy to figure out how it really does its magic. We'll take you through the basics and how ...

Quantum computers will also speed up many difficult optimization problems, where we want to find the "best" way to do something. This will allow us to tackle larger-scale problems in areas such as ...

Microsoft has just announced a chip that it claims will "redefine" how quantum computing works. But experts say there's a long way for that vision to become a reality.

Scientists are excited about the possibility of achieving quantum supremacy because of what it means about the process of creating really useful quantum computers, not necessarily as an end in itself.

Leading theories indicate that a quantum computer capable of breaking RSA would need roughly 4,000 logical qubits. A quantum computer of this size would be useful for many other real-world ...

How does quantum cloud computing work? Akin to platform-as-a-service solutions, quantum cloud computing services work by connecting users directly to quantum processors, emulators and simulators.

We've all read plenty about quantum computing, and its promise for computing breakthroughs. But it isn't easy to figure out how it really does its magic. We'll take you through the basics and how ...

Quantum computers in 2023: how they work, what they do, and where they’re heading Published: October 19, 2023 12:59am EDT. Christopher Ferrie, University of Technology Sydney. Author ...

Quantum computers work differently. They use qubits instead of bits, which can exist in two states simultaneously — like a light switch that can be both on and off at the same time.
