Today’s quantum computers are fundamentally impractical. But with a more resilient qubit, scientists believe they can unlock the technology’s extraordinary potential. Soon, they hope to prove it.

Scientists have recently unveiled a groundbreaking quantum bit, or qubit, design that promises to revolutionize quantum ...

Accessing the 56-qubit Quantinuum System Model H2 trapped-ion quantum computer remotely over the internet, the team generated certifiably random bits.

Fig. 1: Modeling qubits in a realistic way involves large-scale atomistic models with possibly amorphous materials, disorder, ...

Quantum computers aren’t putting standard computers to shame just yet. The most advanced computers are working with fewer than two dozen qubits.

Classical computers use bits to process information, where a bit represents either a zero or a one. By contrast, quantum computing uses qubits—which represent either a zero, a one, or a ...

A Different Qubit A quantum simulator isn't a full-blown quantum computer, let's get that out first. The main difference is that the former is built to solve only one equation model while the ...

Australian researchers have managed to create a CNOT quantum logic gate, the basic building block of a quantum computer, by modifying a standard silicon transistor.

Because quantum systems are inherently noisy and subject to errors, building one logical qubit for a fault-tolerant quantum computer could require combining as many as 1,000 physical qubits.

QuEra Computing, launched by physicists at Harvard and MIT, is trying a different quantum approach to tackle impossibly hard computational tasks.

Programmable optical quantum computer arrives late, steals the show New optical quantum computer overcomes previous limits, looks like a winner.
