Quantum computers promise to solve some problems that are extremely difficult for today’s computers. But there is a major obstacle: quantum information is very fragile, and even tiny disturbances can ...

Researchers have found a way to perform certain quantum operations more than 1,000 times faster, cutting thousands of ...

There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

The computer's master control program. When a computer is turned on, a small "boot program" loads the operating system. Although additional system modules may be loaded as needed, the main part, known ...
