QSlack: A slack-variable approach for variational quantum semi-definite programming
Jingxuan Chen, Hanna Westerheim, Zoë Holmes +6
Solving optimization problems is a key task for which quantum computers could possibly provide a speedup over the best known classical algorithms. Particular classes of optimizatio…
Dual-VQE: A quantum algorithm to lower bound the ground-state energy
Hanna Westerheim, Jingxuan Chen, Zoë Holmes +6
The variational quantum eigensolver (VQE) is a hybrid quantum-classical variational algorithm that produces an upper-bound estimate of the ground-state energy of a Hamiltonian. As…
Limited quantum advantage for stellar interferometry via continuous-variable teleportation
Zixin Huang, Ben Q. Baragiola, Nicolas C. Menicucci +1
We consider stellar interferometry in the continuous-variable (CV) quantum information formalism and use the quantum Fisher information (QFI) to characterize the performance of thr…
Wave Matrix Lindbladization II: General Lindbladians, Linear Combinations, and Polynomials
Dhrumil Patel, Mark M. Wilde
In this paper, we investigate the problem of simulating open system dynamics governed by the well-known Lindblad master equation. In our prequel paper, we introduced an input model…
Quantum Computational Complexity and Symmetry
Soorya Rethinasamy, Margarite L. LaBorde, Mark M. Wilde
Testing the symmetries of quantum states and channels provides a way to assess their usefulness for different physical, computational, and communication tasks. Here, we establish s…
On the optimal error exponents for classical and quantum antidistinguishability
Hemant K. Mishra, Michael Nussbaum, Mark M. Wilde
The concept of antidistinguishability of quantum states has been studied to investigate foundational questions in quantum mechanics. It is also called quantum state elimination, be…
Efficient quantum algorithms for testing symmetries of open quantum systems
Rahul Bandyopadhyay, Alex H. Rubin, Marina Radulaski +1
Symmetry is an important and unifying notion in many areas of physics. In quantum mechanics, it is possible to eliminate degrees of freedom from a system by leveraging symmetry to…
