Abstract: Spin quantum bits (qubits) in semiconductor silicon quantum dots are one of the most promising candidates for large-scale quantum processor units, since they potentially have higher ...

Since that day, LIGO — composed of two highly sensitive laser interferometers located in Hanford, Washington and Livingston, ...

A strange kind of geometry governs how particles move inside matter. Now, for the first time, physicists have uncovered its ...

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), ...

Developing technology that allows quantum information to be both stable and accessible is a critical challenge in the development of useful quantum computers that operate at scale. Research published ...

The algorithm relies on the Kac-Ward formalism, a mathematical method that allows exact computation of partition functions for planar spin glass systems in polynomial time, making it possible to ...

Trust, but verify: Random number generation is a serious matter in modern computing. Most systems rely on a purely hardware-based approach to RNG, but the process is essentially impossible to verify ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Very little in this life is truly random. A coin flip is influenced ...

Angelica Leicht is the senior editor for the Managing Your Money section for CBSNews.com, where she writes and edits articles on a range of personal finance topics. Angelica previously held editing ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

May 27, 2025 marked an important milestone in digital encryption. On that day, scientists introduced a quantum device designed to enhance how random numbers are generated, promising stronger ...
