Osculator wave icon3/17/2023 ![]() ![]() The one-to-one mapping between qubit state and fermion state makes it easy to determine the number of qubits you’ll need to simulate a fermionic process. Those orbitals, in turn, combine to form the electron shells that surround the nucleus.) (You might remember something about the occupation of states from high school chemistry: An atom’s electron orbitals can each be occupied by a maximum of one electron. The qubit’s two-state property means it can represent a fermion state pretty straightforwardly: One qubit state is assigned to “occupied,” and the other, “unoccupied.” Similarly, a fermion state has two distinct modes: occupied and unoccupied. The biggest barrier to modeling bosons related to the properties of a qubit - a quantum bit. “So we took existing fermion models and extended them to include bosons, and we did that in a novel way.” “But in high-energy physics, we also have bosons, and high-energy physicists are particularly interested in the interactions between bosons and fermions,” said Fermilab scientist Jim Amundson, a co-author on the Physical Review Letters paper. Over the last decade, the development of quantum algorithms focused strongly on simulating purely fermionic systems, such as molecules in quantum chemistry. The relative obscurity of bosons in quantum-computation literature has partly to do with bosons themselves and partly with the way quantum-computing research has evolved. “Our method worked, and better than we expected.” “The representation of bosons in quantum computing was never addressed very well in the literature before,” Macridin said. His work is part of the Fermilab quantum science program. But they’ve had a much tougher time doing the same for boson systems.įor the first time, Fermilab scientist Alexandru Macridin has found a way to model systems containing both fermions and bosons on general-purpose quantum computers, opening a door to realistic simulations of the subatomic realm. In recent years, scientists have successfully developed quantum algorithms to compute systems made of fermions. The fundamental particles that make up our universe can be divided into two groups: particles called fermions, which are the building blocks of matter, and particles called bosons, which tug on the matter particles. In a paper published in Physical Review Letters, Fermilab researchers fill a conspicuous gap in modeling the subatomic world using quantum computers, addressing a family of particles that, until recently, has been relatively neglected in quantum simulations. A group of scientists at the Department of Energy’s Fermilab has figured out how to use quantum computing to simulate the fundamental interactions that hold together our universe. ![]()
