Continuous-time noise mitigation in analogue quantum simulation

Gabriele Bressanini, Yue Ma, Hyukjoon Kwon +1

Analogue quantum simulators offer a promising route to explore quantum many-body dynamics beyond classical reach in the near term. However, their vulnerability to noise limits the…

Quantum observables over time for information recovery

Gabriele Bressanini, Farhan Hanif, Hyukjoon Kwon +1

We introduce the concept of quantum observables over time (QOOT), an operator that jointly describes two observables at two distinct time points, as a dual of the quantum state ove…

Multi-parameter quantum estimation of single- and two-mode pure Gaussian states

Gabriele Bressanini, Marco G. Genoni, M. S. Kim +1

We discuss the ultimate precision bounds on the multiparameter estimation of single- and two-mode pure Gaussian states. By leveraging on previous approaches that focused on the est…

Quantum error cancellation in photonic systems -- undoing photon losses

Adam Taylor, Gabriele Bressanini, Hyukjoon Kwon +1

Real photonic devices are subject to photon losses that can decohere quantum information encoded in the system. In the absence of full fault tolerance, quantum error mitigation tec…

Gaussian boson sampling validation via detector binning

Gabriele Bressanini, Benoit Seron, Leonardo Novo +2

Gaussian boson sampling (GBS), a computational problem conjectured to be hard to simulate on a classical machine, has been at the forefront of recent years' experimental and theore…

Gaussian boson sampling at finite temperature

Gabriele Bressanini, Hyukjoon Kwon, M. S. Kim

Gaussian boson sampling (GBS) is a promising candidate for an experimental demonstration of quantum advantage using photons. However, sufficiently large noise might hinder a GBS im…

Gaussian boson sampling with click-counting detectors

Gabriele Bressanini, Hyukjoon Kwon, M. S. Kim

Gaussian boson sampling constitutes a prime candidate for an experimental demonstration of quantum advantage within reach with current technological capabilities. The original prop…

Enhanced nonlinear interferometry via seeding

Jefferson Flórez, Emma Pearce, Nathan R. Gemmell +5

We analyse a nonlinear interferometer, also known as an SU(1,1) interferometer, in the presence of internal losses and inefficient detectors. To overcome these limitations, we cons…

Decoherence and classicalization of continuous-time quantum walks on graphs

Gabriele Bressanini, Claudia Benedetti, Matteo G. A. Paris

We address decoherence and classicalization of continuous-time quantum walks (CTQWs) on graphs. In particular, we investigate three different models of decoherence, and employ the…

Noise thresholds for classical simulability of non-linear Boson sampling

Gabriele Bressanini, Hyukjoon Kwon, M. S. Kim

Boson sampling, a computational problem conjectured to be hard to simulate on a classical machine, is a promising candidate for an experimental demonstration of quantum advantage u…
