Quasi-optimal quantum Markov chain spectral gap estimation

Adam Connolly, Steven Herbert, Julien Sorci

This paper proposes a quantum algorithm for Markov chain spectral gap estimation that is quasi-optimal (i.e., optimal up to a polylogarithmic factor) in the number of vertices for…

Analyzing and improving a classical Betti number estimation algorithm

Julien Sorci

Recently, a classical algorithm for estimating the normalized Betti number of an arbitrary simplicial complex was proposed. Motivated by a quantum algorithm with a similar Monte Ca…

Comparing quantum and classical Monte Carlo algorithms for estimating Betti numbers of clique complexes

Ismail Yunus Akhalwaya, Ahmed Bhayat, Adam Connolly +4

Several quantum and classical Monte Carlo algorithms for Betti Number Estimation (BNE) on clique complexes have recently been proposed, though it is unclear how their performances…

Almost-Optimal Computational Basis State Transpositions

Steven Herbert, Julien Sorci, Yao Tang

We give an explicit construction to perform any -qubit computational basis state transposition using gates. This nearly coincides with the lower bound on…

A Modular Engine for Quantum Monte Carlo Integration

Ismail Yunus Akhalwaya, Adam Connolly, Roland Guichard +8

We present the Quantum Monte Carlo Integration (QMCI) engine developed by Quantinuum. It is a quantum computational tool for evaluating multi-dimensional integrals that arise in va…

Average Mixing in Quantum Walks of Reversible Markov Chains

Julien Sorci

The Szegedy quantum walk is a discrete time quantum walk model which defines a quantum analogue of any Markov chain. The long-term behavior of the quantum walk can be encoded in a…

Continuous-time Quantum Walks on Cayley Graphs of Extraspecial Groups

Peter Sin, Julien Sorci

We study continuous-time quantum walks on normal Cayley graphs of certain non-abelian groups, called extraspecial groups. By applying general results for graphs in association sche…

Minimal Codes From Characteristic Functions Not Satisfying The Ashikhmin-Barg Condition

Julien Sorci

A minimal code is a linear code where the only instance that a codeword has its support contained in the support of another codeword is when the codewords are scalar multiples of e…

Linear representations of finite geometries and associated LDPC codes

Peter Sin, Julien Sorci, Qing Xiang

The {\it linear representation} of a subset of a finite projective space is an incidence system of affine points and lines determined by the subset. In this paper we use character…
