Benchmarking Quantum Instruments
Darian McLaren, Matthew A. Graydon, Ali Assem Mahmoud +1
Quantum measurements with feed-forward are crucial components of fault-tolerant quantum computers. We show how the error rate of such a measurement can be directly estimated by fit…
Weakly Hadamard diagonalizable graphs and Quantum State Transfer
Darian McLaren, Hermie Monterde, Sarah Plosker
Hadamard diagonalizable graphs are undirected graphs for which the corresponding Laplacian is diagonalizable by a Hadamard matrix. Such graphs have been studied in the context of q…
Stochastic errors in quantum instruments
Darian McLaren, Matthew A. Graydon, Joel J. Wallman
Fault-tolerant quantum computation requires non-destructive quantum measurements with classical feed-forward. Many experimental groups are actively working towards implementing suc…
Preserving a qubit during adjacent measurements at a few micrometers distance
Sainath Motlakunta, Nikhil Kotibhaskar, Chung-You Shih +6
Protecting a quantum object against irreversible accidental measurements from its surroundings is necessary for controlled quantum operations. This becomes especially challenging o…
Centralizer clones relative to a strong limit cardinal
Rory B. B. Lucyshyn-Wright, Darian McLaren
The notion of commutation of operations in universal algebra leads to the concept of centralizer clone and gives rise to a well-known class of problems that we call centralizer pro…
The Complete Positivity of Symmetric Tridiagonal and Pentadiagonal Matrices
Lei Cao, Darian McLaren, Sarah Plosker
We provide a decomposition that is sufficient in showing when a symmetric tridiagonal matrix is completely positive. Our decomposition can be applied to a wide range of matrice…
Centrosymmetric Stochastic Matrices
Lei Cao, Darian McLaren, Sarah Plosker
We consider the convex set of stochastic matrices and the convex set of centrosymmetric stochastic matrices (stochastic…
On Operator Valued Measures
Darian McLaren, Sarah Plosker, Christopher Ramsey
We consider positive operator valued measures whose image is the bounded operators acting on an infinite-dimensional Hilbert space, and we relax, when possible, the usual assumptio…
Perfect quantum state transfer in weighted paths with potentials (loops) using orthogonal polynomials
Steve Kirkland, Darian McLaren, Rajesh Pereira +2
A simple method for transmitting quantum states within a quantum computer is via a quantum spin chain---that is, a path on vertices. Unweighted paths are of limited use, and so…
