A new approach to simulate molecules on a quantum computer
At the core
of stakes, we have seven-qubit quantum processor
to address the molecular structure problem; we have near-term quantum systems
to enhance our understanding of complex chemical reactions that could lead to
practical applications; the interplay of atoms and molecules; use quantum
computers to wholly analyze molecules and chemical reactions, more personalized
drugs, or discovery of more efficient and sustainable energy sources, to name a
few.
In effect, IBM scientists have developed
a new approach to simulate molecules on a quantum computer that may one day help
revolutionize chemistry and materials science.
One can
observe that, the scientists successfully used a seven-qubit
quantum processor to address the molecular structure problem for beryllium
hydride (BeH2), the largest molecule simulated on a quantum computer
to date.
According to
IBM, the results demonstrate a path of exploration for near-term quantum
systems to enhance our understanding of complex chemical reactions that could
lead to practical applications.
The team implemented a novel algorithm that is efficient with respect to the number
of quantum operations required for the simulation.
