Imaginary-time-enhanced feedback-based quantum algorithms for universal ground-state preparation
Thanh Nguyen Van Long, Lan Nguyen Tran, Le Bin Ho
Preparing ground states of strongly correlated quantum systems is a central goal in quantum simulation and optimization. The feedback-based quantum algorithm (FALQON) provides an a…
Quantum simulation of strong charge-parity violation and Peccei-Quinn mechanism
Le Bin Ho
Quantum Chromodynamics (QCD) admits a topological term that violates charge-parity () symmetry, yet experiments indicate that is extremely small. To investigate…
Exact gradient for general cost functions in variational quantum algorithms
Jesus Urbaneja, Le Bin Ho
We present a unitary-based gradient formulation for variational quantum algorithms (VQAs) that applies to general differentiable cost function defined by a parameterized quantum ci…
Statistical analysis of barren plateaus in variational quantum algorithms
Le Bin Ho, Jesus Urbaneja, Sahel Ashhab
We investigate the barren plateau (BP) phenomenon in variational quantum algorithms using a statistical approach. Using Gaussian function models, we identify three distinct types o…
