In a continuing effort to improve upon previous work, a research team at the Graduate School of Science, Osaka City University, have applied their recently developed Bayesian phase difference estimation quantum algorithm to perform full configuration interaction (full-CI) calculations of atoms and molecules without simulating the time evolution of the wave function conditional on an ancillary qubit. Superior to conventional methods in terms of parallel execution of quantum gates during quantum computing, this new algorithm is expected to be much easier to implement in actual quantum computers.

A two-dimensional map of proteins, including secondary structures, was obtained for the hindwings of an insect (Anomala albopilosa) at the spatial resolution of 100 ┬Ám. Mapping was achieved with the microscopic vibrational circular dichroism (VCD) system, which has been developed in our laboratory. As a result, the insect hindwing was revealed to be composed of segregated microdomains consisting of proteins with different secondary structures.

Researchers improve their newly established quantum algorithm, bringing it to one-tenth the computational cost of Quantum Phase Estimation, and use it to directly calculate the vertical ionization energies of light atoms and molecules such as CO, O2, CN, F2, H2O, NH3 within 0.1 electron volts of precision.
