Among the current challenges with creating quantum computers is that the timespan that a singular qubit remains coherent is quite limited, restricting their usefulness. Usually such qubits consist ...

MicroCloud’s fast quasi-adiabatic driving via spin-orbit coupling achieves two key breakthroughs: suppressing charge noise to stabilize qubit operations and ensuring precise qubit initialization ...

With quipu, knots in a string represent a number. By analogy, a conventional qubit would be as if you used a string to form a 0 or 1 shape on a tabletop. A breeze or other “noise” would easily ...
