Driven Boson Sampling.

Sampling the distribution of bosons that have undergone a random unitary evolution is strongly believed to be a computationally hard problem. Key to outperforming classical simulations of this task is to increase both the number of input photons and the size of the network. We propose driven boson sampling, in which photons are input within the network itself, as a means to approach this goal. ...

Experimental scattershot boson sampling

Boson sampling is a computational task strongly believed to be hard for classical computers, but efficiently solvable by orchestrated bosonic interference in a specialized quantum computer. Current experimental schemes, however, are still insufficient for a convincing demonstration of the advantage of quantum over classical computation. A new variation of this task, scattershot boson sampling, ...

Microwave boson sampling

The first post-classical computation will most probably be performed not on a universal quantum computer, but rather on a dedicated quantum hardware. A strong candidate for achieving this is represented by the task of sampling from the output distribution of linear quantum optical networks. This problem, known as boson sampling, has recently been shown to be intractable for any classical comput...

The Multiphoton Boson Sampling Machine Doesn't Beat Early Classical Computers for Five-boson Sampling

An ignored algorithm called Store-reuse for calculating the permanent of an n  n matrix is considered. It utilizes computer storages sufficiently, and uses stored data repetitively. The analysis manifests that the numbers of multiplications and additions taken by the Store-reuse algorithm are respectively far smaller than those taken by the famous Ryser's algorithm. As to the 5-boson sampling,...
