The Potential of the SPHEREx Mission for Characterizing PAH 3.3 μm Emission in Nearby Galaxies

Kavli Affiliate: James J. Bock | First 5 Authors: Edward Zhang, Andreas L. Faisst, Brendan Crill, Hanae Inami, Thomas Lai | Summary: Dust is a key galaxy component together with gas, stars, and central supermassive black holes, playing a crucial role in stellar and galaxy evolution. Hence, it is critical to understand galaxies’ dust content […]

Exponential quantum speedups in quantum chemistry with linear depth

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term quantum chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state […]
