Qubit metrology for building a fault-tolerant quantum
... their logic interactions must have errors below a threshold: scaling up with more and more qubits then brings the net error probability down to appropriate levels needed for running complex algorithms. Reducing error requires solving problems in physics, control, materials and fabrication, which dif ...

Solving Momentum Problems
... is moving in the direction opposite that defined as positive will have a negative momentum. You can also break a momentum vector into components or resolve momentum vectors into a single resultant. Momentum is a conserved quantity. The momentum of a system will not change unless an outside impulse i ...

Aspects of the Quantum Hall Effect
... one edge to the other, thereby making it possible to do work against a potential gradient in a direction transverse to the electric current induced by the changing flux. This gives rise to a Hall conductance quantized at integer values. These arguments hold quite generally – immune to details of the ...
