Sampling of bosonic qubits
Vincenzo Tamma
The boson sampling problem has brought a lot of attention in the quantum information field because it is not efficiently solvable with a classical computer; nonetheless it can be i…
Factoring numbers with a single interferogram
Vincenzo Tamma, Heyi Zhang, Xuehua He +3
We construct an analog computer based on light interference to encode the hyperbolic function f(ζ) = 1/ζ into a sequence of skewed curlicue functions. The resulting interferogram w…
Improved scaling of Time-Evolving Block-Decimation algorithm through Reduced-Rank Randomized Singular Value Decomposition
D. Tamascelli, R. Rosenbach, M. B. Plenio
When the amount of entanglement in a quantum system is limited, the relevant dynamics of the system is restricted to a very small part of the state space. When restricted to this s…
Entropic uncertainty bound for open pointer-based simultaneous measurements of conjugate observables
Raoul Heese, Matthias Freyberger
We discuss the information entropy for a general open pointer-based simultaneous measurement and show how it is bound from below. This entropic uncertainty bound is a direct conseq…
Equivalence of Statistical Mechanical Ensembles for Non-Critical Quantum Systems
Fernando G. S. L. Brandao, Marcus Cramer
We consider the problem of whether the canonical and microcanonical ensembles are locally equivalent for short-ranged quantum Hamiltonians of spins arranged on a -dimensiona…
Efficiency of quantum controlled non-Markovian thermalization
Victor Mukherjee, Vittorio Giovannetti, Rosario Fazio +3
We study optimal control strategies to optimize the relaxation rate towards the fixed point of a quantum system in the presence of a non-Markovian dissipative bath. Contrary to nai…
