Optimal Linear-Rate Conversion of Unknown Mixed Qubit States via SWAP Tests
Sujay Kazi, Iman Marvian
By consuming multiple copies of an unknown qubit state, one can modify its purity while preserving the direction of its Bloch vector. We determine the maximum linear rate at which…
Optimal Distillation of Qubit Clocks
Sujay Kazi, Iman Marvian
We study coherence distillation under time-translation-invariant operations: given many copies of a quantum state containing coherence in the energy eigenbasis, the aim is to produ…
Analyzing the quantum approximate optimization algorithm: ansätze, symmetries, and Lie algebras
Sujay Kazi, Martín Larocca, Marco Farinati +3
The Quantum Approximate Optimization Algorithm (QAOA) has been proposed as a method to obtain approximate solutions for combinatorial optimization tasks. In this work, we study the…
Showcasing a Barren Plateau Theory Beyond the Dynamical Lie Algebra
N. L. Diaz, Diego García-Martín, Sujay Kazi +2
Barren plateaus have emerged as a pivotal challenge for variational quantum computing. Our understanding of this phenomenon underwent a transformative shift with the recent introdu…
On the universality of -equivariant -body gates
Sujay Kazi, Martin Larocca, M. Cerezo
The importance of symmetries has recently been recognized in quantum machine learning from the simple motto: if a task exhibits a symmetry (given by a group ), the le…
