Efficient Quantum Circuits for Electronic Hamiltonian Simulation without Pauli Expansion
Tamiya Onodera, Takeshi Sato
Electronic Hamiltonian simulation is commonly formulated by mapping fermionic operators to qubit operators and subsequently expanding the resulting ladder-operator products into Pa…
