General protocols for the efficient distillation of indistinguishable photons

J Saied, J Marshall, N Anand, EG Rieffel - arXiv preprint arXiv:2404.14217, 2024 - arxiv.org
Highly pure and indistinguishable photons are a prerequisite for use in quantum information
processing. We introduce protocols for the distillation of indistinguishable photons that offer …

Simulating imperfect quantum optical circuits using unsymmetrized bases

J Steinmetz, M Ostmann, A Neville, B Pankovich… - arXiv preprint arXiv …, 2024 - arxiv.org
Fault-tolerant photonic quantum computing requires the generation of large entangled
resource states. The required size of these states makes it challenging to simulate the effects …

Distinguishability-induced many-body decoherence

C Dittel, A Buchleitner - New Journal of Physics, 2024 - iopscience.iop.org
We show that many-body interference phenomena are exponentially suppressed in the
particle number, if the identical quantum objects brought to interference acquire a finite level …

Fourier analysis of many-body transition amplitudes and states

G Dufour, A Buchleitner - arXiv preprint arXiv:2409.15079, 2024 - arxiv.org
We apply the Fourier transform over the symmetric group $ S_N $ to the set of multiparticle
transition amplitudes arising from the permutations of $ N $ identical particles. This allows us …
