Beyond real: Investigating the role of complex numbers in self-testing
Ranyiliu Chen, Laura Mančinska, Jurij Volčič
We investigate complex self-testing, a generalization of standard self-testing that accounts for quantum strategies whose statistics is indistinguishable from their complex conjuga…
Classification and implementation of unitary-equivariant and permutation-invariant quantum channels
Laura Mančinska, Elias Theil
Many quantum information tasks use inputs of the form , which naturally induce permutation and unitary symmetries. We classify all quantum channels that respect both…
Quantum Advantage with Faulty Oracle
David Rasmussen Lolck, Laura Mančinska, Manaswi Paraashar
This paper investigates the impact of noise in the quantum query model, a fundamental framework for quantum algorithms. We focus on the scenario where the oracle is subject to non-…
Sample Optimal and Memory Efficient Quantum State Tomography
Yanglin Hu, Enrique Cervero-Martín, Elias Theil +2
Quantum state tomography is the fundamental physical task of learning a complete classical description of an unknown state of a quantum system given coherent access to many identic…
A memory and gate efficient algorithm for unitary mixed Schur sampling
Enrique Cervero-Martín, Laura Mančinska, Elias Theil
We formalize the task of unitary Schur sampling -- an extension of weak Schur sampling -- which is the process of measuring the Young label and the unitary group register of an inp…
Weak Schur sampling with logarithmic quantum memory
Enrique Cervero, Laura Mančinska
The quantum Schur transform maps the computational basis of a system of qudits onto a \textit{Schur basis}, which spans the minimal invariant subspaces of the representations o…
Glued magic games self-test maximally entangled states
Laura Mančinska, Thor Gabelgaard Nielsen, Jitendra Prakash
Self-testing results allow us to infer the underlying quantum mechanical description of states and measurements from classical outputs produced by non-communicating parties. The st…
Maximally entangled states in pseudo-telepathy games
Laura Mančinska
A pseudo-telepathy game is a nonlocal game which can be won with probability one using some finite-dimensional quantum strategy but not using a classical one. Our central question…
