Quasi-exact quantum computation
Dong-Sheng Wang, Guanyu Zhu, Cihan Okay +1
We study quasi-exact quantum error correcting codes and quantum computation with them. A quasi-exact code is an approximate code such that it contains a finite number of scaling pa…
Classifying space for quantum contextuality
Cihan Okay, Daniel Sheinbaum
We construct a topological space to study contextuality in quantum mechanics. The resulting space is a classifying space in the sense of algebraic topology. Cohomological invariant…
Phase space simulation method for quantum computation with magic states on qubits
Robert Raussendorf, Juani Bermejo-Vega, Emily Tyhurst +2
We propose a method for classical simulation of finite-dimensional quantum systems, based on sampling from a quasiprobability distribution, i.e., a generalized Wigner function. Our…
Homotopical approach to quantum contextuality
Cihan Okay, Robert Raussendorf
We consider the phenomenon of quantum mechanical contextuality, and specifically parity-based proofs thereof. Mermin's square and star are representative examples. Part of the info…
