In the previous article titled “The Basics: How Quantum Computers Work and Where the Technology is Heading,” we provided an overview of foundational quantum computing concepts, including qubits ...

One intriguing method that could be used to form the qubits needed for quantum computers involves electrons hovering above liquid helium. But it wasn't clear how data in this form could be read easily ...

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 ...

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 ...

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

With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to ...

David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), ...

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 ...

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 ...

Foundational to the work on quantum error correction (QEC) are logical qubits, which are created by entangling multiple physical qubits, whose quantum state can be destroyed by environmental noise ...

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.

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