A general approach to backaction-evading receivers with magnetomechanical and electromechanical sensors
Brittany Richman, Sohitri Ghosh, Daniel Carney +4
Today's mechanical sensors are capable of detecting extremely weak perturbations while operating near the standard quantum limit. However, further improvements can be made in both…
Subsystem CSS codes, a tighter stabilizer-to-CSS mapping, and Goursat's Lemma
Michael Liaofan Liu, Nathanan Tantivasadakarn, Victor V. Albert
The CSS code construction is a powerful framework used to express features of a quantum code in terms of a pair of underlying classical codes. Its subsystem extension allows for si…
Projective toric designs, quantum state designs, and mutually unbiased bases
Joseph T. Iosue, T. C. Mooney, Adam Ehrenberg +1
Toric -designs, or equivalently -designs on the diagonal subgroup of the unitary group, are sets of points on the torus over which sums reproduce integrals of degree mono…
