Quantum computing with holes

“On top, we added tiny electrical wires – so-called gates – to control the movement of holes by applying voltage to them. Superconductors – materials without any electrical resistance – support the linking of several qubits due to their quantum-mechanical nature. ” Using this nano-scale control, the…

Weird World of Quantum Black Holes – “May Be Radically Different from What Einstein Predicted and Lack Event Horizons”

Weird World of Quantum Black Holes – “May Be Radically Different from What Einstein Predicted and Lack Event Horizons”

According to Hawking’s 1974 conjecture, if one takes quantum theory into account, black holes should glow slightly with “Hawking radiation”. The Daily Galaxy, Maxwell Moe, astrophysicist, NASA Einstein Fellow, University of Arizona…

CMOS controller for quantum computer operates at 3 K – Physics World

CMOS controller for quantum computer operates at 3 K – Physics World

Writing in Nature, they report that their cryo-controller, called Horse Ridge, directed operations on a silicon-based quantum chip as successfully as more standard, off-the-shelf room temperature electronics. The cryo-controller is based on complementary metal-oxide-semiconductor (CMOS) technology, which is a…
