Improving the efficiency of quantum algorithms for complex molecules

Polynomial scaling localized active space unitary selective coupled cluster singles and doubles

Journal of Chemical Theory and Computation (2025)

Researchers have developed a more efficient preselection step for quantum algorithms to help quantum computers simulate complex molecules.

The method focuses only on the most important parts of the molecule and selects the most relevant quantum interactions using a smart filtering system.

The team tested this method on several molecular systems, including chains of carbon atoms and a chromium-based molecule, to check how accurate and practical the results are.

Their approach reduces memory demands for selection and helps estimate the quantum resource requirements for simulating larger, more realistic chemical systems in the future — something current quantum hardware can’t yet handle.

Shreya Verma, Ruhee D’Cunha, Abhishek Mitra, Matthew Hermes, Stephen Gray, Matt Otten and Laura Gagliardi conducted this research, working at the University of Chicago, the University of Wisconsin–Madison and Argonne National Laboratory.

Helium lifts new quantum computing concept

A team led by Jacob Covey, who is part of Q-NEXT and is an Associate Professor at the University of Chicago, laid out a new concept that could turn helium’s light weight into the next generation of quantum computers. The design relies on helium-3, an isotope with different quantum properties than the helium-4 used to cool MRI machines and fill party balloons. Once built, the computer could use high-powered lasers as “optical tweezers” to capture and control individual atoms of helium. Read More

Silicon Chip Offers New Way to Probe Quantum Materials in Strong Magnetic Fields

Scientists have created a silicon chip that can detect the electrical behavior of very small materials by using very high-frequency waves. The chip is made only from silicon and other non-superconducting materials and still performs very well when cooled from room temperature down to about 4 Kelvin. Read More
