Quantum computing leverages quantum physics for complex computations beyond classical computers. IBM’s Quantum System 2 is a significant milestone, utilizing qubits that can exist in superposition.

A quantum computer with 4 qubits can in theory handle 16 times as much information as an equally-sized conventional computer and will keep doubling in power with every qubit that’s added.

Quantum computing represents a monumental shift in computational power, capable of solving problems that were once thought impossible. While challenges remain, breakthroughs like Majorana 1 hint ...

Quantum computing predates cloud computing by quite some time. Quantum computing is still mostly physics. Here is a quote from a report produced at the end of the 20th century, in 1999: ...

His explorations in quantum thermodynamics, electron-photon interactions, and liquid helium made him realize that the complex equations weren’t solvable by classical computers. It’s an issue ...

Route Optimization. One of the most exciting applications of quantum computing in logistics is its potential to tackle the Traveling Salesman Problem (TSP)—a longstanding challenge in route ...

AI is the technology trend of the moment—but what’s 10 years down the road? Some experts say quantum computing will be the next game-changer. WSJ visited IBM’s quantum computing lab to learn ...
