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

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 ...

Two companies that are racing to develop a photonic quantum computer using photonic qubits are PsiQuantum, based in Palo Alto ...

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

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 ...

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.

Chemistry professor Danna Freedman crafts “designer molecules” for quantum information science. It all began with a simple origami model. As an undergrad at Harvard, Danna Freedman went to a professor ...

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 Researchers ...

Currently, he says, Constellation has modeled computers of up to 97 qubits, and it can be used to go even higher. “We know how to make qubits work,” he says. “Now we see it as the engineering task to ...

Researchers affiliated with Caltech and the quantum computing startup Oratomic have published a preprint claiming that Shor’s ...
