Quantum superiority for verifying NP-complete problems with linear optics
Juan Miguel Arrazola, Eleni Diamanti, Iordanis Kerenidis
Demonstrating quantum superiority for some computational task will be a milestone for quantum technologies and would show that computational advantages are possible not only with a…
Efficient quantum pseudorandomness with simple graph states
Rawad Mezher, Joe Ghalbouni, Joseph Dgheim +1
Measurement based (MB) quantum computation allows for universal quantum computing by measuring individual qubits prepared in entangled multipartite states, known as graph states. U…
Rates of multi-partite entanglement transformations and applications in quantum networks
A. Streltsov, C. Meignant, J. Eisert
The theory of the asymptotic manipulation of pure bipartite quantum systems can be considered completely understood: The rates at which bipartite entangled states can be asymptotic…
Verification of quantum computation: An overview of existing approaches
Alexandru Gheorghiu, Theodoros Kapourniotis, Elham Kashefi
Quantum computers promise to efficiently solve not only problems believed to be intractable for classical computers, but also problems for which verifying the solution is also cons…
Continuous-Variable Sampling from Photon-Added or Photon-Subtracted Squeezed States
Ulysse Chabaud, Tom Douce, Damian Markham +3
We introduce a new family of quantum circuits in Continuous Variables and we show that, relying on the widely accepted conjecture that the polynomial hierarchy of complexity classe…
Amending entanglement-breaking channels via intermediate unitary operations
Álvaro Cuevas, Antonella De Pasquale, Andrea Mari +9
We report a bulk optics experiment demonstrating the possibility of restoring the entanglement distribution through noisy quantum channels by inserting a suitable unitary operation…
