Seminario de hoy Jueves

[Bernardo Wolf <bwolf@xxxxxxxxxxx>]

Estimad@s Colegas,

Los invitamos al Seminario del Instituto del día de hoy, jueves 11 de
noviembre, a las 5:30pm en el auditorio del instituto, con el título:

Linear canonical transforms in quantum computation and wave
optics.
Dr. John J. Healy,  ICF 

Resumen:
Hadamard matrices are square, unimodular, unitary matrices which are
useful in quantum computing as they define Weyl pairs of
observables.
Discrete linear canonical transforms (LCTs) are square, unimodular
matrices with physical realisations. Hence, when discrete LCTs are
unitary, they constitute realisable Hadamard matrices. We discuss
when discrete LCTs are unitary, and when sets of these matrices form
mutually unbiased bases. Discrete LCTs are also used in numerical
approximation of paraxial wave propagation through lens systems. We
show how to select sampling rates in such simulations.
