(AnalyticsIndia) Recently, a team of researchers from IBM came up with a solution for quantum computers that require fewer qubits. The new solution is claimed to boost the accuracy and performance of chemical simulations on quantum computers as opposed to the classical computer quantum computers that require a large number of qubits to work efficiently.
IBM collaborated with Daimler AG and Virginia Tech to build quantum computers that use fewer qubits. To that end, the researchers combined quantum simulation methods with Hamiltonian function. In comoutaion, Hamiltonian function represents a change in a molecule’s kinetic and potential energy.
The researchers said, “We chose a third path, using a Hamiltonian which is “transcorrelated”, i.e. transformed to provide additional information about some of the interactions that need a larger basis set for accurate description and, hence, can’t fit into the quantum computer using a traditional Hamiltonian.”
The new method enables quantum simulations based on a transcorrelated Hamiltonian that approximately incorporates the electron-electron cusp and as a result, provides a more accurate simulation of the molecule, without the need for more qubits or deeper quantum circuits.
