Quantum Simulation of Boson-Related Hamiltonians: Techniques, Effective Hamiltonian Construction, and Error Analysis
Bo Peng, Yuan Su, Daniel Claudino +3
A broad spectrum of physical systems in condensed-matter and high-energy physics, vibrational spectroscopy, and circuit and cavity QED necessitates the incorporation of bosonic deg…
Fast quantum simulation of electronic structure by spectrum amplification
Guang Hao Low, Robbie King, Dominic W. Berry +6
The most advanced techniques using fault-tolerant quantum computers to estimate the ground-state energy of a chemical Hamiltonian involve compression of the Coulomb operator throug…
Classical shadows of fermions with particle number symmetry
Guang Hao Low
We consider classical shadows of fermion wavefunctions with particles occupying modes. We prove that all -Reduced Density Matrices (RDMs) may be simultaneously estimate…
Trading T gates for dirty qubits in state preparation and unitary synthesis
Guang Hao Low, Vadym Kliuchnikov, Luke Schaeffer
Efficient synthesis of arbitrary quantum states and unitaries from a universal fault-tolerant gate-set e.g. Clifford+T is a key subroutine in quantum computation. As large quantum…
