The density matrix renormalization group method is employed for classical precomputation in this work. Our method uses mutual information between the qubits in classically approximated ground state to rank and screen the entanglers. In this work, we propose a way to construct entangler pools with reduced size by leveraging classical algorithms. Those algorithms aim to build up optimal circuits for a certain problem and ansatz circuits are adaptively constructed by selecting and adding entanglers from a predefined pool. Roller coasters are an entertaining way to utilize potential energy – chains are used to move a car up an incline (building up gravitational potential energy), to then have that energy converted into kinetic energy as it falls.Īnother practical use is utilizing gravitational potential energy to descend (perhaps coast) downhill in transportation such as the descent of an automobile, truck, railroad train, bicycle, airplane, or fluid in a pipeline.Adaptive construction of ansatz circuits offers a promising route towards applicable variational quantum eigensolvers on near-term quantum hardware. It's also used by counterweights for lifting up an elevator, crane, or sash window. The negative value for gravitational energy also has deeper implications that make it seem more reasonable in cosmological calculations where the total energy of the universe can meaningfully be considered see inflation theory for more on this. Where Δ U at infinity is by far the more preferable choice, even if the idea of negative energy in a gravity well appears to be peculiar at first. Thermal energy usually has two components: the kinetic energy of random motions of particles and the potential energy of their configuration.įorces derivable from a potential are also called conservative forces. Chemical potential energy, such as the energy stored in fossil fuels, is the work of the Coulomb force during rearrangement of configurations of electrons and nuclei in atoms and molecules. For example, the work of an elastic force is called elastic potential energy work of the gravitational force is called gravitational potential energy work of the Coulomb force is called electric potential energy work of the strong nuclear force or weak nuclear force acting on the baryon charge is called nuclear potential energy work of intermolecular forces is called intermolecular potential energy. There are various types of potential energy, each associated with a particular type of force. 6 Potential energy for electrostatic forces between two bodies.5 Potential energy for gravitational forces between two bodies.3 Potential energy for near Earth gravity.Since the work of potential forces acting on a body that moves from a start to an end position is determined only by these two positions, and does not depend on the trajectory of the body, there is a function known as potential that can be evaluated at the two positions to determine this work. These forces, that are called conservative forces, can be represented at every point in space by vectors expressed as gradients of a certain scalar function called potential. Potential energy is associated with forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space. The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concept of potentiality. The unit for energy in the International System of Units (SI) is the joule, which has the symbol J. Ĭommon types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
