As exciting as it may be to hear about a breakthrough 127-qubit quantum computer or promises of 1,000 qubits by 2023, the reality is that quantum computing is still not a mainstream computing ...

Quantum computers, on the other hand, have qubits. Qubits exist in a superposition between 0 and 1, and when you try to observe their state, you force them to choose between the two.

New optical quantum computer overcomes previous limits, ... two carbon atoms and two hydrogen atoms—and the more complicated phenylvinylacetylene—the favorite child's name for 2021—successfully.

This is the dawn of Quantum Computing 2.0—where accessibility, scalability, and practicality take center stage,” said Jason Lynch, CEO of Equal1 “By eliminating the barriers of cost, ...

AI can help discover new materials, but we’ll need quantum computers to really move the needle. On January 8, Nvidia CEO Jensen Huang jolted the stock market by saying that practical quantum ...

IBM wants to scale up its quantum computers to over 4,000 qubits by 2025 — but we’re not quite there yet. For now, ... up from the 127 qubits of its 2021 Eagle processor.

Most researchers have never seen a quantum computer. Winfried Hensinger has five. “They’re all terrible,” he says. “They can’t do anything useful.” In fact, all quantum computers could ...
