High-accuracy adaptive quantum tomography for high-dimensional quantum systems
L. Pereira, D. Martínez, G. Cañas +4
The accuracy of estimating -dimensional quantum states is limited by the Gill-Massar bound. It can be saturated in the qubit () scenario using adaptive standard quantum tom…
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…
Computational advantage from quantum superposition of multiple temporal orders of photonic gates
Márcio M. Taddei, Jaime Cariñe, Daniel Martínez +9
Models for quantum computation with circuit connections subject to the quantum superposition principle have been recently proposed. There, a control quantum system can coherently d…
Experimental quantum tomography assisted by multiply symmetric states in higher dimensions
D. Martínez, M. A. Solís-Prosser, G. Cañas +3
High-dimensional quantum information processing has become a mature field of research with several different approaches being adopted for the encoding of -dimensional quantum sy…
