A “Hamiltonian” is a quantum mechanical energy operator that describes the interactions between all the electron orbitals* and nuclei of the constituent atoms.
The “lowest energy” state of the molecular Hamiltonian dictates the structure of the molecule and how it will interact with other molecules.
IBM scientists have developed a new approach to simulate molecules on a quantum computer that may one day help revolutionize chemistry and materials science.
The scientists successfully used six qubits on a purpose-built seven-qubit quantum processor to address the molecular structure problem for beryllium hydride (Be H2) – the largest molecule simulated on a quantum computer to date.
What are their limitations, and how do researchers expect to overcome them?
https://arxiv.org/abs/1801.00862"Noisy Intermediate-Scale Quantum (NISQ) technology will be available in the near future.
The particular encoding from orbitals to qubits studied in this work can be used to simplify simulations of even larger molecule and we expect the opportunity to explore such larger simulations in the future, when the quantum computational power (or “quantum volume”) of IBM Q systems has increased.
While Be H is the largest molecule ever simulated by a quantum computer to date, the considered model of the molecule itself is still simple enough for classical computers to simulate exactly.
Such information is critical for chemists to design new molecules, reactions, and chemical processes for industrial applications.
*A couple of notes about orbitals: One, electrons don’t spin around an atom’s nucleus like planets around the Sun, as is often depicted in simplistic cartoons.
