The appeal of adiabatic quantum computing lies not only in its simplicity, but also in its versatility.

Hong was convinced that a simple model of adiabatic expansion — the rapid diffusion of gas that occurs, for example, when a balloon bursts — could explain what happens when popcorn kernels explode.

D - Wave instead uses adiabatic quantum computing, in which an array of chilled, superconducting niobium loops — the qubits in this system — very quickly find the lowest point in what can be thought of as an energy «landscape» of hills and valleys.

But adiabatic computing is a much newer field and so much less of the theory is known.

Previous research suggests that adiabatic quantum computers are especially good at optimization problems, which involve finding the best solution from all feasible solutions, such as the shortest route connecting multiple destinations, or the most stable form of molecules — the former problem could help Mars rovers better explore the red planet, while the latter could lead to better drugs or catalysts.

The Google - led project combines the advantages of both the main forms of quantum computing by using a standard quantum computer to simulate an adiabatic quantum computer.

The ratio between the trends should follow moist adiabatic independent of where El Niño's occur though.

Indeed, there is a clear physical reason why this is the case — the increase in water vapour as surface air temperature rises causes a change in the moist - adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).

The dry adiabatic lapse rate is g / cp, where g is the acceleration of gravity and cp is the specific heat at constant pressure.

(PS diffusion of matter and energy (latent heat) during such phase changes requires compositional and temperature gradients — entropy must then be produced, so there is a departure from actually being adiabatic — a smaller departure if pressure is being changed less rapidly (so that diffusions occur across smaller gradients).
