Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called ...

Caltech scientists have built a record-breaking array of 6,100 neutral-atom qubits, a critical step toward powerful error-corrected quantum computers. The qubits maintained long-lasting superposition ...

One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a ...

Quantum physics is the branch of science that deals with the tiniest particles in the universe, such as atoms, electrons, photons (light particles), and other subatomic particles like quarks. In the ...

Microsoft announced last month it had created a “topological qubit,” which the company says can power a quantum computer more reliably than previously developed quantum qubits and which they believe ...

Quantum circuits are systems consisting of logic gates that operate on quantum bits (qubits) to process information and perform calculations based on principles of quantum mechanics. Quantum circuits ...

Physicists have demonstrated a quantum machine that could reduce errors in quantum computers by ensuring that the qubits they use remain in their initial state before a calculation starts. The quantum ...

A collaborative research project between scientists at the University of São Paulo (IFSC-USP) in ...

There's a lot of interest in quantum computing in the banking world, but outside specialized teams at large institutions that have invested in it, there is a lack of clarity on what it is, how it ...

Forbes contributors publish independent expert analyses and insights. Tim Bajarin covers the tech industry’s impact on PC and CE markets. Two years ago, I spent about six months in deep discussions ...
