(PhysOrg.com) -- To build a quantum computer, it's essential to be able to quickly and efficiently manipulate the quantum states of qubits. The qubits, which are the basic unit of quantum information, can be composed of many ...
(PhysOrg.com) -- Researchers at HP Labs, the central research arm of HP, have discovered that a resistor with memory, a “memristor” can also perform logic operations. This means chips storing data may also be able to ...
(PhysOrg.com) -- Physicists at the National Institute of Standards and Technology have built an enhanced version of an experimental atomic clock based on a single aluminum atom that is now the world’s most precise clock, ...
