Minimal orthonormal bases for pure quantum state estimation
Leonardo Zambrano, Luciano Pereira, Aldo Delgado
We present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite-dimensional Hilbert space. This is optimal as two bases are…
Avoiding barren plateaus in the variational determination of geometric entanglement
Leonardo Zambrano, Andrés Damián Muñoz-Moller, Mario Muñoz +2
The barren plateau phenomenon is one of the main obstacles to implementing variational quantum algorithms in the current generation of quantum processors. Here, we introduce a meth…
Stochastic optimization algorithms for quantum applications
J. Gidi, B. Candia, A. D. Muñoz-Moller +5
Hybrid classical quantum optimization methods have become an important tool for efficiently solving problems in the current generation of NISQ computers. These methods use an optim…
Training quantum measurement devices to discriminate unknown non-orthogonal quantum states
D. Concha, L. Pereira, L. Zambrano +1
Here, we study the problem of decoding information transmitted through unknown quantum states. We assume that Alice encodes an alphabet into a set of orthogonal quantum states, whi…
Variational determination of multi-qubit geometrical entanglement in NISQ computers
A. D. Muñoz-Moller, L. Pereira, L. Zambrano +2
Current noise levels in physical realizations of qubits and quantum operations limit the applicability of conventional methods to characterize entanglement. In this adverse scenari…
Scalable estimation of pure multi-qubit states
L. Pereira, L. Zambrano, A. Delgado
We introduce an inductive -qubit pure-state estimation method. This is based on projective measurements on states of separable bases or entangled bases plus the compu…
Estimation of pure quantum states in high dimension at the limit of quantum accuracy through complex optimization and statistical inference
Leonardo Zambrano, Luciano Pereira, Sebastian Niklitschek +1
Quantum tomography has become a key tool for the assessment of quantum states, processes, and devices. This drives the search for tomographic methods that achieve greater accuracy.…
Estimation of pure states using three measurement bases
L. Zambrano, L. Pereira, D. Martínez +3
We introduce a new method to estimate unknown pure -dimensional quantum states using the probability distributions associated with only three measurement bases. Measurement resu…
