Superconducting qubits—bits of quantum information—have been widely considered a promising technology for moving quantum ...

When we measure a qubit in superposition, it picks one state, like a spinning coin landing heads or tails. This is called ...

Quantum computing is no longer science fiction confined to the lab. It is a new computing paradigm with the potential to solve problems beyond the reach of classical systems. From simulating complex ...

Researchers at QuTech in Delft, The Netherlands, have developed a new chip architecture that could make it easier to test and scale up quantum processors based on semiconductor spin qubits. The ...

Foundational to the work on quantum error correction (QEC) are logical qubits, which are created by entangling multiple ...

Quantum computing is a largely theoretical, ultimately expensive proposition for high-level computation. However, new ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...

Quantum computers hold the potential to revolutionize the possibilities for solving difficult computational problems that would take classical computers many years to resolve. But for those computers ...

A team of scientists from the University of Chicago, the University of California Berkeley, Argonne National Laboratory, and Lawrence Berkeley National Laboratory has developed molecular qubits that ...
