Implementation and verification of coherent error suppression using randomized compiling for Grover's algorithm on a trapped-ion device
Masatoshi Ishii, Hammam Qassim, Tomochika Kurita +4
In near-term quantum computations that do not employ fault tolerant error correction, noise can proliferate rapidly, corrupting the quantum state and making results unreliable. The…
Synergetic quantum error mitigation by randomized compiling and zero-noise extrapolation for the variational quantum eigensolver
Tomochika Kurita, Hammam Qassim, Masatoshi Ishii +3
We propose a quantum error mitigation strategy for the variational quantum eigensolver (VQE) algorithm. We find, via numerical simulation, that very small amounts of coherent noise…
Efficiently improving the performance of noisy quantum computers
Samuele Ferracin, Akel Hashim, Jean-Loup Ville +7
Using near-term quantum computers to achieve a quantum advantage requires efficient strategies to improve the performance of the noisy quantum devices presently available. We devel…
Improved upper bounds on the stabilizer rank of magic states
Hammam Qassim, Hakop Pashayan, David Gosset
In this work we improve the runtime of recent classical algorithms for strong simulation of quantum circuits composed of Clifford and T gates. The improvement is obtained by establ…
Classical vs. quantum satisfiability in linear constraint systems modulo an integer
Hammam Qassim, Joel. J. Wallman
A system of linear constraints can be unsatisfiable and yet admit a solution in the form of quantum observables whose correlated outcomes satisfy the constraints. Recently, it has…
Clifford recompilation for faster classical simulation of quantum circuits
Hammam Qassim, Joel J. Wallman, Joseph Emerson
Simulating quantum circuits classically is an important area of research in quantum information, with applications in computational complexity and validation of quantum devices. On…
Quantum walks and wavepacket dynamics on a lattice with twisted photons
Filippo Cardano, Francesco Massa, Hammam Qassim +8
The "quantum walk" has emerged recently as a paradigmatic process for the dynamic simulation of complex quantum systems, entanglement production and quantum computation. Hitherto,…
Real-time imaging of spin-to-orbital angular momentum quantum state teleportation
Manuel Erhard, Hammam Qassim, Harjaspreet Mand +2
Quantum teleportation is a process in which an unknown quantum state is transferred between two spatially separated subspaces of a bipartite quantum system which share an entangled…
Photonic quantum walk in a single beam with twisted light
Filippo Cardano, Francesco Massa, Ebrahim Karimi +6
Inspired by the classical phenomenon of random walk, the concept of quantum walk has emerged recently as a powerful platform for the dynamical simulation of complex quantum systems…
Limitations to the determination of a Laguerre-Gauss spectrum via projective, phase-flattening measurement
Hammam Qassim, Filippo M. Miatto, Juan P. Torres +3
One of the most widely used techniques for measuring the orbital angular momentum components of a light beam is to flatten the spiral phase front of a mode, in order to couple it t…
